      Note:

        Platform specific notes regarding specific operating systems may
        be found in the PLATFORMS.txt file.  This file (README.txt) provides
        generic instructions which work in most common cases.  Additional
        notes regarding Cygwin & MinGW are provided later in this file.

      Type:

        gzip -dc ImageMagick-5.5.6.tar.gz | tar xvf -
        cd ImageMagick-5.5.6

      If you do not have gzip(1), the source for the gzip package is
      available as a shell archive at

        ftp://ftp.gnu.org/gnu/gzip/gzip-1.2.4a.shar

      or as a tar archive at

      Use 'configure' to automatically configure, build, and install
      ImageMagick. The configure script may be executed from the ImageMagick
      source directory (e.g ./configure) or from a seperate build directory by
      specifying the full path to configure (e.g.
      /src/ImageMagick-5.5.6/configure). The advantage of using a seperate
      build directory is that multiple ImageMagick builds may share the same
      ImageMagick source directory while allowing each build to use a unique
      set of options.

      If you are willing to accept configure's default options, and build from
      within the source directory, type:

          ./configure

      and watch the configure script output to verify that it finds everything
      that you think it should. If it does not, then adjust your environment
      so that it does.

      By default, `make install' will install the package's files
      in `/usr/local/bin', `/usr/local/man', etc. You can specify an
      installation prefix other than `/usr/local' by giving `configure'
      the option `--prefix=PATH'.  This is valuable in case you don't have
      privileges to install under the default paths or if you want to install
      in the system directories instead.

      If you are not happy with configure's choice of compiler, compilation
      flags, or libraries, you can give `configure' initial values for
      variables by specifying them on the configure command line, e.g.:

          ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix

      Options which should be common to packages installed under the same
      directory heirarchy may be supplied via a 'config.site' file located
      under the installation prefix via the path ${prefix}/share/config.site
      where ${prefix} is the installation prefix.  This file is used for all
      packages installed under that prefix.  This is an example config.site
      file:

      # Configuration values for all packages installed under this prefix
      CC=gcc
      CXX=c++
      CPPFLAGS='-I/usr/local/include'
      LDFLAGS='-L/usr/local/lib -R/usr/local/lib'

      When the 'config.site' file is being used to supply configuration
      options, configure will issue a message similar to:

        configure: loading site script /usr/local/share/config.site

      The configure variables you should be aware of are:

          CC          Name of C compiler (e.g. 'cc -Xa') to use
          CXX         Name of C++ compiler to use (e.g. 'CC')
          CFLAGS      Compiler flags (e.g. '-g -O2') to compile C code
          CXXFLAGS    Compiler flags (e.g. '-g -O2') to compile C++ code
          CPPFLAGS    Include paths (-I/somedir) to look for header files
          LDFLAGS     Library paths (-L/somedir) to look for libraries
                      Systems that support the notion of a library run-path
                      may require an additional argument in order to find
                      shared libraries at run time. For example, the Solaris
                      linker requires an argument of the form '-R/somedir',
                      some Linux systems will work with '-rpath /somedir',
                      while some other Linux systems who's gcc does not pass
                      -rpath to the linker require an argument of the form
                      '-Wl,-rpath,/somedir'.
          LIBS        Extra libraries (-lsomelib) required to link

      Any variable (e.g. CPPFLAGS or LDFLAGS) which requires a directory
      path must specify an absolute path rather than a relative path.

      Configure can usually find the X include and library files
      automatically, but if it doesn't, you can use the `configure' options
      `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations.

      The configure script provides a number of ImageMagick specific
      options.  When disabling an option --disable-something is equivalent to
      specifying --enable-something=no and --without-something is equivalent
      to --with-something=no.  The configure options are as
      follows (execute 'configure --help' to see all options).

       --without-zlib          disable ZLIB support
       --with-x                use the X Window System
       --with-share-path=DIR   Alternate path to share directory
                               (default share/ImageMagick)
       --with-libstdc=DIR      use libstdc++ in DIR (for GNU C++)

      ImageMagick options represent either features to be enabled, disabled,
      or packages to be included in the build.  When a feature is enabled (via
      --enable-something), it enables code already present in ImageMagick.
      When a package is enabled (via --with-something), the configure script
      will search for it, and if is is properly installed and ready to use
      (headers and built libraries are found by compiler) it will be included
      in the build.  The configure script is delivered with all features
      disabled and all packages enabled. In general, the only reason to
      disable a package is if a package exists but it is unsuitable for
      the build (perhaps an old version or not compiled with the right
      compilation flags).

      Several configure options require special note:

        o --enable-shared: the shared libraries are built. Shared
          libraries are preferred because they allow programs to share
          common code, making the individual programs much smaller. In
          addition shared libraries are required in order for PerlMagick to
          be dynamically loaded by an installed PERL (otherwise an additional
          PERL (PerlMagick) must be installed. This option is not the default
          because all libraries used by ImageMagick must also be dynamic
          libraries if ImageMagick itself is to be dynamically loaded (such
          as for PerlMagick).

          ImageMagick built with delegates (see MAGICK PLUG-INS below)
          can pose additional challenges. If ImageMagick is built using
          static libraries (the default without --enable-shared) then
          delegate libraries may be built as either static libraries or
          shared libraries. However, if ImageMagick is built using shared
          libraries, then all delegate libraries must also be built as
          shared libraries.  Static libraries usually have the extension .a,
          while shared libraries typically have extensions like .so, .sa,
          or .dll. Code in shared libraries normally must compiled using
          a special compiler option to produce Position Independent Code
          (PIC). The only time this is not necessary is if the platform
          compiles code as PIC by default.

          PIC compilation flags differ from vendor to vendor (gcc's is
          -fPIC). However, you must compile all shared library source with
          the same flag (for gcc use -fPIC rather than -fpic). While static
          libraries are normally created using an archive tool like 'ar',
          shared libraries are built using special linker or compiler options
          (e.g. -shared for gcc).

          Building shared libraries often requires subtantial hand-editing
          of Makefiles and is only recommended for those who know what they
          are doing.

          If --enable-shared is not specified, a new PERL interpreter
          (PerlMagick) is built which is statically linked against the
          PerlMagick extension. This new interpreter is installed into the
          same directory as the ImageMagick utilities. If --enable-shared
          is specified, the PerlMagick extension is built as a dynamically
          loadable object which is loaded into your current PERL interpreter
          at run-time. Use of dynamically-loaded extensions is preferable over
          statically linked extensions so --enable-shared should be specified
          if possible (note that all libraries used with ImageMagick must
          be shared libraries!).

        o --disable-static: static archive libraries (with extension .a)
          are not built.  If you are building shared libraries, there
          is little value to building static libraries. Reasons to build
          static libraries include: 1) they can be easier to debug; 2) the
          clients do not have external dependencies (i.e. libMagick.so); 3)
          building PIC versions of the delegate libraries may take additional
          expertise and effort; 4) you are unable to build shared libraries.

        o --with-modules: image format coders are built as loadable modules
          which are installed in [prefix]/lib/ImageMagick/modules/coders.
          Support for modules allows the formats supported by ImageMagick
          to be extended by simply adding additional modules to the module
          search path.  The modules option is only available in conjunction
          with --enable-shared.  If --enable-shared is not also specified,
          then support for modules is disabled.

        o --enable-lzw: Unisys claims a patent on the algorithm supporting
          LZW compression (e.g. used by GIF and TIFF). To avoid possibly
          infringing on this patent, support for LZW is disabled by default.
          With LZW support, GIF files written by ImageMagick will be much
          larger than expected. Note that the TIFF library must be patched
          in order to support LZW compression, and that this support must
          be explicitly enabled in the libtiff Makefiles.

        o --with-quantum-depth: This option allows the user to specify the
          number of bits to use per pixel quantum (the size of the red,
          green, blue, and alpha pixel components. For example,
          "--with-quantum-depth=8" builds ImageMagick using 8-bit quantums.
          Most computer display adaptors use 8-bit quantums. Currently
          supported arguments are 8, 16, or 32. The default is 16. This
          option is the most important option in determining the overall
          run-time performance of ImageMagick.

          The number of bits in a quantum determines how many values it may
          contain. Each quantum level supports 256 times as many values as
          the previous level. The following table shows the range available
          for various quantum sizes.

              QuantumDepth  Valid Range (Decimal)  Valid Range (Hex)
                    8            0-255                   00-FF
                   16           0-65535                0000-FFFF
                   32         0-4294967295         00000000-FFFFFFFF

          Larger pixel quantums cause ImageMagick to run more slowly and to
          require more memory. For example, using sixteen-bit pixel quantums
          causes ImageMagick to run 15% to 50% slower (and take twice as
          much memory) than when it is built to support eight-bit pixel
          quantums.

          The amount of virtual memory consumed by an image can be computed
          by the equation (QuantumDepth*Rows*Columns*5)/8. This is an
          important consideration when resources are limited, particularly
          since processing an image may require several images to be in
          memory at one time. The following table shows memory consumption
          values for a 1024x768 image:

              QuantumDepth  Virtual Memory
                  8              3MB
                 16              8MB
                 32             15MB

        o --without-magick-plus-plus: Disable building Magick++, the C++
          application programming interface to ImageMagick. A suitable C++
          compiler is required in order to build Magick++. Specify the CXX
          configure variable to select the C++ compiler to use (default
          "g++"), and CXXFLAGS to select the desired compiler opimization
          and debug flags (default "-g -O2"). Antique C++ compilers will
          normally be rejected by configure tests so specifying this option
          should only be necessary if Magick++ fails to compile.

        o --without-frozenpaths: Normally full paths to external programs
          (based on searching the PATH set when configure is run) will be
          saved to the delegates.mgk file. Specify this option to disable
          saving full paths to programs.

        o --without-threads: By default, the ImageMagick library is compiled
          with multi-thread support.  If this is undesireable, then specify
          --without-threads.

        o --with-cache: Specify a different image pixel cache threshold
          using the --with-cache option. This sets the maximum amount of
          heap memory that ImageMagick is allowed to consume before
          switching to using memory-mapped temporary files to store raw
          pixel data.

        o --disable-largefile: By default, ImageMagick is compiled with
          support for large (> 2GB on a 32-bit CPU) files if the operating
          system supports large files.  All applications which use the
          ImageMagick library must then also include support for large
          files. By disabling support for large files via --disable-largefile,
          dependent applications do not require special compilation options
          for large files in order to use the library.

        o --without-perl: By default, PerlMagick is conveniently compiled
          and installed as part of ImageMagick's normal "configure", "make",
          "make install" process.. When --without-perl is specified, you must
          first install ImageMagick, change to the PerlMagick subdirectory,
          build, and finally install PerlMagick. Note, PerlMagick is
          configured even if --without-perl is specified. If the argument
          --with-perl=/path/to/perl is supplied, then /path/to/perl will be
          taken as the PERL interpreter to use. This is important in case the
          'perl' executable in your PATH is not PERL5, or is not the PERL
          you want to use.

        o --with-perl-options: The PerlMagick module is normally installed
          using the Perl interpreter's installation PREFIX, rather than
          ImageMagick's. If ImageMagick's installation prefix is not
          the same as PERL's PREFIX, then you may find that PerlMagick's
          'make install' step tries to install into a directory tree that
          you don't have write permissions to. This is common when PERL is
          delivered with the operating system or on Internet Service Provider
          (ISP) web servers. If you want PerlMagick to install elsewhere,
          then provide a PREFIX option to PERL's configuration step via
          "--with-perl-options=PREFIX=/some/place". Other options accepted by
          MakeMaker are 'LIB', 'LIBPERL_A', 'LINKTYPE', and 'OPTIMIZE'. See
          the ExtUtils::MakeMaker(3) manual page for more information on
          configuring PERL extensions.

        o --without-x: By default, ImageMagick will use X11 libraries if
          they are available. When --without-x is specified, use of X11 is
          disabled. The display, animate, and import programs are not built or
          installed. The remaining programs have reduced functionality such
          as no access to X11 fonts (consider using Postscript or TrueType
          fonts instead).

        o --with-gs-font-dir: Specify the directory containing the
          Ghostscript Postscript Type 1 font files (e.g. "n022003l.pfb") so
          that they can be rendered using the FreeType library. If the font
          files are installed using the default Ghostscript installation paths
          (${prefix}/share/ghostscript/fonts), they should be discovered
          automatically by configure and specifying this option is not
          necessary. Specify this option if the Ghostscript fonts fail to
          be located automatically, or the location needs to be overridden.

        o --with-windows-font-dir: Specify the directory containing
          MS-Windows-compatible fonts. This is not necessary when ImageMagick
          is running under MS-Windows.

      Building under Cygwin

        ImageMagick may be built under the Windows '95-XP Cygwin
        Unix-emulation environment available for free from

          http://www.cygwin.com/

        X11R6 for Cygwin is available from

          http://xfree86.cygwin.com/

        It is strongly recommended that the
        X11R6 package be installed since this enables ImageMagick's X11
        support (animate, display, and import will work) and it includes the
        Freetype v2 DLL required to support TrueType and Postscript Type 1
        fonts. Make sure that /usr/X11R6/bin is in your PATH prior to running
        configure. If you are using Cygwin version 1.3.9 or later, you may
        specify the configure option '--enable-shared' to build Cygwin DLLs.
        Specifying '--enable-shared' is required if you want to build
        PerlMagick under Cygwin because Cygwin does not provide the libperl.a
        static library required to create a static PerlMagick.

      Building under MinGW & MSYS

        ImageMagick may be built using the free MinGW ("Minimalistic GNU for
        Windows") package version 1.1, available from

          http://www.mingw.org

        which consists of a GNU-based (e.g. gcc) compilation toolset plus
        headers and libraries required to build programs which are entirely
        based on standard Microsoft Windows DLLs. MSYS provides a Unix-like
        console shell window with sufficient functionality to run the
        ImageMagick configure script and execute make.

        Unlike the Cygwin build which creates programs based on a
        Unix-emulation DLL, and which uses Unix-style paths to access
        Windows files, the MinGW build creates native Windows console
        applications similar to the Visual C++ build.

        Please note that since the MinGW build is very new, some aspects of
        the installation may vary from Windows user's expectations, and that
        only a static build (no DLLs or modules) is currently supported.

        Once MinGW & MSYS have been installed, start the MSYS console (via
        the MSYS icon on the Windows desktop) and follow the Unix configure
        and build instructions. Note that the default installation prefix is
        "/usr/local" which installs the package into a MSYS directory. To
        install outside of the MSYS directory tree, you may specify an
        installation prefix like "/c/ImageMagick" which causes the package
        to be installed under the Windows directory "C:\ImageMagick". The
        installation directory structure will look very much like the Unix
        installation layout (e.g. "C:\ImageMagick\bin",
        "C:\ImageMagick\lib", "C:\ImageMagick\share", etc.). Any additional
        delegate libraries (e.g. libpng) will need to be built under MinGW
        in order to be used.

      Dealing with configuration failures:

        While configure is designed to ease installation of ImageMagick, it
        often discovers problems that would otherwise be encountered later
        when compiling ImageMagick. The configure script tests for headers
        and libraries by executing the compiler (CC) with the specified
        compilation flags (CFLAGS), pre-processor flags (CPPFLAGS), and linker
        flags (LDFLAGS). Any errors are logged to the file 'config.log'. If
        configure fails to discover a header or library please review this
        log file to determine why, however, please be aware that *errors
        in the config.log are normal* because configure works by trying
        something and seeing if it fails. An error in config.log is only a
        problem if the test should have passed on your system. After taking
        corrective action, be sure to remove the 'config.cache' file before
        running configure so that configure will re-inspect the environment
        rather than using cached values.

        Common causes of configure failures are: 1) a delegate header is
        not in the header include path (CPPFLAGS -I option); 2) a delegate
        library is not in the linker search/run path (LDFLAGS -L/-R option);
        3) a delegate library is missing a function (old version?); 4)
        compilation environment is faulty.

        If all reasonable corrective actions have been tried and the
        problem appears to be due to a flaw in the configure script,
        please send a bug report to the configure script maintainer
        (currently bfriesen@simple.dallas.tx.us). All bug reports should
        contain the operating system type (as reported by 'uname -a')
        and the compiler/compiler-version. A copy of the configure script
        output and/or the config.log file may be valuable in order to find
        the problem. If you send a config.log, please also send a script of
        the configure output and a description of what you expected to see
        (and why) so the failure you are observing can be identified and
        resolved.

      Makefile Build Targets

        Once ImageMagick is configured, these standard build targets are
        available from the generated Makefiles:

           'make'
              Build the package

           'make install'
              Install the package

           'make check'
              Run tests using the installed ImageMagick ('make install' must
              be done first!).

           'make clean'
              Remove everything in the build directory created by 'make'

           'make distclean'
              Remove everything in the build directory created by 'configure'
              and 'make'. This is useful if you want to start over from scratch.

           'make uninstall'
         	Remove all files from the system which are (or would be)
         	installed by 'make install' using the current configuration.
              Note that this target is imperfect for PerlMagick since Perl
              no longer supports an 'uninstall' target.

      Build & Install:

        Now that ImageMagick is configured, type

           make

        to build the package and

           make install

        to install it.

      Verifying The Build:

        To confirm your installation of the ImageMagick distribution was
        successful, type:

            ./utilities/display

        The ImageMagick logo is displayed.

        If the image colors are not correct use this command:

            ./utilities/display -visual default

        For a more serious test, you may run the ImageMagick test suite by
        typing

            make check

        Note that due to differences between the developer's environment and
        your own it is possible that some tests may be indicated as failed
        even though the results are ok. Differences between the developer's
        environment environment and your own may include the compiler, the
        CPU type, and the library versions used. The ImageMagick developers
        use the current release of all dependent libraries.

      Documentation:

        Be sure to read the manual pages for the display(1), animate(1),
        montage(1), import(1), mogrify(1), identify(1), composite(1), and
        convert(1) utilities. The ImageMagick(1) manual page provides details
        for utility options and will also aid with understanding library
        interfaces. Also read the ImageMagick frequently asked questions in
        the file www/Magick.html.

      X11 Resources:

        Place display(1) X application defaults in
        /usr/lib/X11/app-defaults/Display or in a directory specified by the
        XUSERFILESEARCHPATH environment variable. Use the appropriate name
        for other clients (e.g. Animate, Montage, etc). To execute display(1)
        from as a menu item of any window manager (olwm, mwm, twm, etc), use

           display logo:Untitled

    MAGICK DELEGATES

      To further enhance the capabilities of ImageMagick, you may want to
      get these programs or libraries:

        o ImageMagick requires the BZLIB library from

            http://sourceware.cygnus.com/bzip2/index.html

          to read and write BZip compressed MIFF images.

        o ImageMagick requires ralcgm from

            http://www.agocg.ac.uk/train/cgm/ralcgm.htm

          to read the Computer Graphics Metafile image format (may not
          compile under linux).  You also need Ghostscript (see below).

        o ImageMagick requires fig2dev from

            ftp://ftp.x.org/contrib/applications/drawing_tools/transfig

          to read the Fig image format.

        o ImageMagick requires the FreeType software, version 2.0 or above,
          available as

            http://www.freetype.org/

          to annotate with TrueType and Postscript Type 1 fonts.

        o ImageMagick requires Ghostscript software available from

            http://www.cs.wisc.edu/~ghost/

          to read the Postscript or the Portable Document format. It is used
          to annotate an image when the FreeType library is not used, or an
          X server is not available. See the FreeType library above for
          another means to annotate an image. Note, Ghostscript must support
          the ppmraw device (type gs -h to verify). If Ghostscript is
          unavailable, the Display Postscript extension is used to rasterize
          a Postscript document (assuming you define HasDPS). The DPS
          extension is less robust than Ghostscript in that it will only
          rasterize one page of a multi-page document.

          Ghostscript (released 7.0 and later) may optionally install a
          library (libgs). If this library is installed, ImageMagick will
          attempt to use it unless the option --without-gslib is passed to
          configure. Note that Ghostscript provides its own modified version
          of libjpeg and that symbols from this libjpeg may be confused with
          symbols with the stand-alone libjpeg. If conflicts cause JPEG to
          fail, it may be necessary to use Ghostscript's copy of libjpeg for
          ImageMagick, and all delegate libraries which depend on libjpeg.

        o ImageMagick requires hp2xx available from

             http://www.gnu.org/software/hp2xx/hp2xx.html

          to read the HP-GL image format. Note that HPGL is a plotter file
          format. HP printers usually accept PCL format rather than HPGL
          format.

        o ImageMagick requires the LCMS library available from

             http://www.littlecms.com/

          to perform color management.

        o ImageMagick requires gnuplot available via anonymous FTP as

             ftp://ftp.dartmouth.edu/pub/gnuplot/gnuplot-3.7.tar.gz

          to read GNUPLOT plot files (with extension gplt).

        o ImageMagick requires html2ps available from

             http://www.tdb.uu.se/~jan/html2ps.html

          to read the HTML image format.

        o ImageMagick requires the JBIG-Kit software available via
          HTTP from

             http://www.cl.cam.ac.uk/~mgk25/jbigkit/

          or via anonymous FTP as

             ftp://ftp.informatik.uni-erlangen.de/pub/doc/ISO/JBIG/

          to read the JBIG image format.

        o ImageMagick requires the Independent JPEG Group's software
          available via anonymous FTP as

             ftp://ftp.uu.net/graphics/jpeg/jpegsrc.v6b.tar.gz

          to read the JPEG v1 image format.

          Apply this JPEG patch to Independent JPEG Group's source
          distribution if you want to read lossless jpeg-encoded DICOM
          (medical) images:

             ftp://ftp.imagemagick.org/pub/ImageMagick/delegates/ljpeg-6b.tar.gz

          Use of lossless JPEG is not encouraged. Unless you have a requirement
          to read lossless jpeg-encoded DICOM images, please disregard the patch.

        o ImageMagick requires the JasPer Project's Jasper library available
          via http from

             http://www.ece.uvic.ca/~mdadams/jasper/

          to read and write the JPEG v2 format.

        o ImageMagick requires the MPEG utilities from the MPEG Software
          Simulation Group, which are available via anonymous FTP as

             ftp://ftp.mpeg.org/pub/mpeg/mssg/mpeg2vidcodec_v12.tar.gz

          to read or write the MPEG image format.

        o ImageMagick requires the PNG library, version 1.0 or above, from

             http://www.libpng.org/pub/png/pngcode.html

          to read the PNG image format.

        o ImageMagick requires ra_ppm from Greg Ward's Radiance software
          available from

             http://radsite.lbl.gov/radiance/HOME.html

          to read the Radiance image format.

        o ImageMagick requires rawtorle from the Utah Raster Toolkit
          available via anonymous FTP as

             ftp://ftp.cs.utah.edu/pub/dept/OLD/pub/urt-3.1b.tar.Z

          to write the RLE image format (may not compile under linux).

        o ImageMagick requires scanimage from

             http://www.mostang.com/sane/

          to import an image from a scanner device.

        o ImageMagick requires Sam Leffler's TIFF software available via
          anonymous FTP at

             ftp://ftp.remotesensing.org/pub/libtiff/

          or via HTTP at

             http://www.libtiff.org/

          to read the TIFF image format. It in turn optionally requires the
          JPEG and ZLIB libraries. Support for JPEG, ZIP, and LZW compression
          must be explicitly enabled by editing libtiff Makefiles. The TIFF
          library no longer includes support for LZW compression due to patent
          issues. If you need to use LZW compression, support is available via
          a seperate LZW compression kit (a patch) at the sites listed above.

        o ImageMagick requires libwmf 0.2.5 (or 0.2.2) available from

             http://sourceforge.net/projects/wvware/

          to render files in the Windows Meta File (WMF) metafile format
          (16-bit WMF files only, not 32-bit "EMF"). This is the format
          commonly used for Windows clipart (available on CD at your local
          computer or technical book store). WMF support requires the
          FreeType 2 library in order to render TrueType and Postscript fonts.

          While ImageMagick uses the libwmflite (parser) component of the
          libwmf package which does not depend on any special libraries, the
          libwmf package as a whole depends on FreeType 2 and either the
          xmlsoft libxml, or expat libraries. Since ImageMagick already uses
          libxml (for reading SVG and to retrieve files via HTTP or FTP), it
          is recommended that the options '--without-expat --with-xml' be
          supplied to libwmf's configure script. To configure libwmf so that
          only libwmflite is built (no libwmf, or wmf utilities), use the
          libwmf configure option --disable-heavy.

          ImageMagick's WMF renderer provides some of the finest WMF
          rendering available due its use of antialiased drawing algorithms.
          You may select a background color or texture image to render on.
          For example, "-background '#ffffffff'" renders on a transparent
          background while "-texture plasma:fractal" renders on a fractal
          image.

          The WMF renderer is not capable of using Windows fonts with libwmf
          0.2.2. Windows fonts are fully supported when using libwmf 0.2.5
          or later.

        o ImageMagick requires the FlashPIX library version 1.2.0 from
          the Digital Imaging Group in order to support the FlashPIX
          format. The FlashPIX library may be obtained from ImageMagick
          anonymous CVS by checking out the 'fpx' module, or retrieving the
          file libfpx-1.2.0.4.tar.gz from the ftp directory

             ftp://ftp.imagemagick.org/pub/ImageMagick/delegates/.

        o ImageMagick requires an X server for display and animate to work
          properly. Unix systems usually provide an X server as part of
          their standard installation.

          A free X server for Microsoft Windows is available from

             http://sources.redhat.com/win32-x11/

          The Cygwin port of XFree86 may also be used. It is available from

             http://www.cygwin.com/xfree/

          There is a nearly free X server available for Windows and
          Macintosh at

             http://www.microimages.com/freestuf/mix/

        o ImageMagick requires libxml available from

             http://xmlsoft.org/

          to read the SVG image format and to retrieve files from over a
          network via FTP and HTTP.

        o ImageMagick requires the ZLIB library from

             http://www.gzip.org/zlib/

          to read or write the PNG or Zip compressed MIFF images.

        o ImageMagick requires a background texture for the TILE
          format and for the -texture option of montage(1).  You can use
          your own or get samples from

             http://the-tech.mit.edu/KPT/

    VMS COMPILATION

      You might want to check the values of certain program definitions
      before compiling.  Verify the definitions in delegates.mgk to suit
      your local requirements.  Next, type.

      Type

          unzip ImageMagick-5.5.6.zip set default [.imagemagick] @make set
          display/create/node=node_name::

      where node_name is the DECNET X server to contact.

      Finally type:

          display

      Alternatively, get a zipped distribution (with JPEG, PNG, TIFF, TTF)
      from

          ftp://ftp.imagemagick.org/pub/ImageMagick/vms/ImageMagick-5.5.6.zip

      Thanks to pmoreau@cenaath.cena.dgac.fr for supplying invaluable help
      as well as the VMS versions of the JPEG, PNG, TTF, and TIFF
      libraries.

    Windows Win2K/95 VISUAL C++ 6.0 COMPILATION

     [ Visual C++ 7.0 users may follow this proceedure, however, once the
       workspace and project files have been converted to the new "Solution"
       format, the configured Visual C++ 6.0 workspace and project files are
       no longer used. This currently puts Visual C++ 7.0 users at a
       disadvantage. ]

      The Visual C++ distribution targeted at Windows Win2K or Windows 95
      does not provide any stock workspace (DSW) or project files (DSP)
      except for those included with third party libraries. Instead, there
      is a "configure" program that must be built and run that creates an
      environment that meets your particular needs.

      The Visual C++ working environment provides a large number of mutually
      exclusive options that must all be used in a coherent manner, or
      problems result.

      The Visual C++ system provides three different types of "runtimes"
      that must match across all application, library, and DLL code that is
      built. The "configure" program creates a set of build files that are
      consistent for a specific runtime selection.

      The three options for runtime support are:

        1) Dynamic Multi-threaded DLL runtimes.
        2) Static Single-threaded runtimes
        3) Static Multi-threaded runtimes
        4) Static Multi-threaded DLL runtimes

      In addition to these runtimes, the VisualMagick build environment
      allows you to select whether to include the X11 libraries in the build
      or use X11 "stubs". Either option is available because X11 DLLs are
      provided with the VisualMagick build environment. Most Windows users
      do not use X11 so they can accept the default X11 "stubs" option.
      Users that use X11 or want to build a full ImageMagick, will want to
      de-select the X11 "stubs" option. When X11 is stubbed out, the X11
      utility programs animate, display, and import will not work.

      This leads to five different possible build options, which should
      cover almost any particular situation. The default binary distribution
      is built using #1 from above with the X11 libraries included. This
      results in an X11 compatible build using all DLL's for everything and
      multi-threaded support (the only option for DLL's).

      To do a build for your requirements, simply go to the configure sub-
      directory under VisualMagick and open the configure.dsw workspace. Set
      the build configuration to "Release" under the

          "Build..., Set Active Configuration..."  menu.

      Build and execute the configure program and follow the instructions.
      You should probably not change any of the defaults unless you have a
      specific reason to do so.

      The configure program provides a button entitled

         Edit "magick_config.h"

      Clicking this button brings up magick_config.h in Windows notepad for
      changing any preprocessor defines in ImageMagick's magick_config.h file.
      This file is copied to magick\magick_config.h. You may safely modify
      magick\magick_config.h and recompile without re-running the configure
      program.

      Key user tunables in magick_config.h include:

        QuantumDepth (default 16)

          Specify size of PixelPacket color Quantums (8, 16, or 32) A value
          of 8 uses half the memory than 16 and may run 30% faster, but
          provides 256 times less color precision than a value of 16.

        UseInstalledImageMagick (default undefined)

          Define to build an ImageMagick which uses registry settings or
          embedded paths to locate installed components (coder modules and
          configuration files). The default is to look for all files in the
          same directory as the executable.

        ProvideDllMain (default undefined)

          Define to include a DllMain() function ensures that the ImageMagick
          DLL is properly initialized without participation from dependent
          applications.

        Windows95 (default undefined)

          Define to allow binaries to execute under Windows '95. Note that
          enabling support for Windows '95 disables support for the large
          (>2GB) pixel cache.

        HasLZW (default undefined)

          Define to enable use of LZW compression in GIF, Postscript, PDF,
          and TIFF. Enabling LZW for TIFF also requires enabling LZW in the
          TIFF library. Note that LZW compression is patented by Unisys so it
          can not be used without a license.

      After creating your build environment you can proceed to open the DSW
      file that was generated in the VisualMagick directory and build
      everything from there.

      In the final DSW file you will find a project call "All". In order to
      build everything in the distribution, select this project and make it
      the "active" project. Set the build configuration to the desired one
      (Debug, or Release) and do a "clean" followed by a "build". You should
      do the build in a specific way:

        1) Make the "All" project the active project (Bold)
           Right click on the All project and select "Set As Active Project"
        2) Select "Build..., Clean"
        3) Select "Build..., Build"
        4) Go get some coffee unless you have a very fast machine!.

      The "Clean" step is needed in order to make sure that all of the target
      support libraries are updated with any patches needed to get them to
      compile properly under Visual C++.

      All of the required files that are needed to run any of the command
      line tools will be found in the "bin" subdirectory of the VisualMagick
      subdirectory. This includes EXE, and DLL files. You should be able
      to test the build directly from this directory without having to move
      anything to any of the global SYSTEM or SYSTEM32 areas in the operating
      system installation.

      NOTE #1:

      The Visual C++ distribution of ImageMagick comes with the Magick++
      C++ wrapper by default. This add-on layer has a large number of demo
      and test files that can be found in ImageMagick\Magick++\demo, and
      ImageMagick\Magick++\tests. There are also a variety of tests that
      use the straight C API as well in ImageMagick\tests.

      All of these programs are NOT configured to be built in the default
      workspace created by the configure program. You can cause all of these
      demos and test programs to be built by checking the box in configure
      that says:

        "Include all demo and test programs"

      In addition, there is another related checkbox (checked by default)
      that causes all generated project files to be created standalone so
      that they can be copied to other areas of you system.

      This is the checkbox:

       "Generate all utility projects with full paths rather then relative
        paths"

      WOW - that a mouthfull - eh?

      The problem is that Visual C++ uses a concept of "dependencies" that
      tell it what other things need to be build when a particular project
      is being build. This mechanism is also used to cause things to link
      properly. In my normal development environment, I want to be able to
      make changes and debug the system as a whole, so I like and NEED to
      use dependencies. However, most end users don't want to work this way.

      Instead they really just want to build the package and then get down
      to business working on their application. The solution is to make all
      the utility projects (UTIL_xxxx_yy_exe.dsp) use full absolute paths
      to all the things they need. This way the projects stand on their own
      and can actually be copied and used as templates to get a particular
      custom application compiling with little effort.

      With this feature enabled, you should be able to nab a copy of...

        VisualMagick\utilities\UTIL_convert_xxx_exe.dsp  (for C)

         -or-

        VisualMagick\Magick++\demo\UTIL_demo_xxx_exe.dsp (for C++)

      ... and pop it into notepad, modify it (carefully) to your needs and
      be on your way to happy compiling and linking.

      You can feel free to pick any of the standard utilities, tests, or
      demo programs as the basis for a new program by copying the project
      and the source and hacking away.

      The choice of what to use as a starting point is very easy...

      For straight C API command line applications use something from:

        ImageMagick\tests or ImageMagick\utilities (source code)
        ImageMagick\VisualMagick\tests or ImageMagick\Visualmagick\utilities
          (project - DSP)

      For C++ and Magick++ command line applications use something from:

        ImageMagick\Magick++\tests or ImageMagick\Magick++\demo
          (source code)
        ImageMagick\VisualMagick\Magick++\tests or
          ImageMagick\VisualMagick\Magick++\demo (project - DSP)

      For C++ and Magick++ and MFC windows applications use:

        ImageMagick\contrib\win32\MFC\NtMagick (source code)
        ImageMagick\VisualMagick\contrib\win32\MFC\NtMagick
          (project - DSP)

      NOTE #2:

      The ImageMagick distribution is very modular. The default
      configuration is there to get you rolling, but you need to make some
      serious choices when you wish to change things around.

      The binary distribution and default options are all targeted at
      having all the components in one place - the "bin" directory of the
      VisualMagick build tree AND the C:\ImageMagick folder.

      The C:\ImageMagick folder should contain the following files:

          1) magic.mgk
          2) delegates.mgk (derived from nt.mgk)
          3) modules.mgk
          4) rgb.txt

      The "bin" folder should contains all EXE's and DLL's as well as the
      very important "modules.mgk" file.

      With this default setup, you can use any of the command line tools
      and run scripts as normal. You can actually get by quite nicely this
      way by doing something like "pushd e:\xxx\yyy\bin" in any scripts you
      write to execute "out of" this directory.

      ALSO, By default the core of ImageMagick on Win32 always looks in the
      place were the exe program is run from in order to find all of the
      files as well as the DLL's it needs.

      Of course - all of this is configurable and there are certain
      environment variables and compiler switches that allow you to do
      whatever you want. Some of these are Windows things and the rest are
      looked at by the core ImageMagick code.

      ENVIRONMENT VARIABLES:

      You can use the "System" control panel to allow you to add and delete
      what is in any of the environment variables. You can even have user
      specific environment variables if you wish.

      PATH

       This sets the default list of places were Windows looks for EXE's and
       DLL's. Windows CMD shell seems to look in the "current" directory first
       - no matter what, so that is why you really don't have to muck. If
       you wish to run any of utilities from another location then you must
       add the path to your "bin" directory in. For instance, you might add:

          D:\CVS\ImageMagick\VisualMagick\bin

       to do this for the default build environment like I do.  One slight
       problem with this is that fact that Windows has another program called
       "convert". I usually rename this to something else since it is only
       used to convert disks from FAT to NTFS.

      MAGICK_HOME

       If all you do is modify the PATH variable, the first problem you
       will run into is that ImageMagick may not be able to find any of
       its "modules. Modules are all the IM_MOD*.DLL files you see in the
       distribution. There is one of these for each and every file format
       that ImageMagick supports. This environment variable tells the system
       were to look for these DLL's. The compiled in "default" is "execution
       path" - which says - look in the same place that the application is
       running "in". If you are running from somewhere other then "bin" -
       this will no longer work and you must use this variable. If you elect
       to leave the modules in the same place as the EXE's (a good idea)
       then you can simply set this to the same place
       as you did the PATH variable. In my case:

          D:\\ImageMagick\coders

       This is also the place were ImageMagick expects to find the
       "colors.mgk", "delegates.mgk", "magic.mgk", "modules.mgk", and
       "type.mgk" files.

       One cool thing about the modules build of ImageMagick is that you can
       now leave out file formats and lighten you load. If all you ever need
       is GIF and JPEG, then simply drop all the other DLL's into the local
       trash can and get on with your life.

       WARNING: Always keep the "xc" format, since IM uses it for internal
       purposes.

      ALSO. You can elect to changes these things the good old "hard-coded"
      way. Two #defines are applicable.

      defines.h has

          #define MagickConfigurePath  "c:\\ImageMagick\\"

      NOTE #3:

      The two utilities "display" and "animate" will only be usable when
      the real X11 libraries are included. The other build environments
      uses the X11 stubs to supply non-functional stubs for the X-Window
      functionality. There is no support for a "static" build of the X11
      support because the build procedures for the X11 libraries do not seem
      to support this.

      To view any image in a Microsoft window, type

          convert image.ext win:

      Make sure Ghostscript is installed, otherwise, you will be unable to
      convert or view a Postscript document.

      Make sure iexplore (Internet Explorer) is in your execution path,
      otherwise, you will be unable to browse the ImageMagick documentation.

      The Win2K executables will work under Windows 95/98.

    MACINTOSH MacOS 9 COMPILATION

      The Macintosh distribution contains MetroWerks Codewarrior Professional
      projects for compilation.  For those who do not have access to
      CodeWarrior, the binaries for the command line utilities are enclosed.
      I had to comment the inline intrinsic functions in math.h in order
      to compile.  If you have a better solution, let me know.

      Display(1), animate(1), and import(1) currently do not work on the
      Macintosh.

    Magick++

      Magick++ provides a straightforward C++ language API to ImageMagick.
      Magick++ is built by default under the Unix, Windows, and Mac build
      environments. To disable building Magick++ under Unix, specify
      --without-magick-plus-plus as an argument to the configure script.

      Magick++ is currently supported using the following C++ compilers:

        gcc 2.95.2 (or later)
        Visual C++ 6.0 (Windows)
        Visual C++ 7.0 (Windows)
        IRIX C++ 7.3.1.1m
        HP-UX HP-UX aCC A.03.30
        Sun Workshop 5.0 C++ (tests/demos require work-around to build)
        Sun Forte 6.0 C++
        CodeWarrior Professional Release 5 (Macintosh)

      and may compile under other modern C++ compilers as well.
