# FUNCTION DESCRIPTIONS

## DestroyMagick

> DestroyMagick() destroys the ImageMagick environment.

The format of the DestroyMagick function is:

> DestroyMagick ( void );

## DestroyMagickInfo

> DestroyMagickInfo() deallocates memory associated MagickInfo list.

The format of the DestroyMagickInfo method is:

> void DestroyMagickInfo ( void );

## GetImageMagick

> GetImageMagick() searches for an image format that matches the specified magick string. If one is found the name is returned otherwise NULL.

The format of the GetImageMagick method is:

> const char *GetImageMagick ( const unsigned char *magick, const size_t length );

A description of each parameter follows:

o magick:
  The image format we are searching for.

o length:
  The length of the binary string.

## GetMagickInfo

> GetMagickInfo() returns a pointer MagickInfo structure that matches the specified name. If name is NULL, the head of the image format list is returned.

The format of the GetMagickInfo method is:

> const MagickInfo *GetMagickInfo ( const char *name, Exception *exception );

A description of each parameter follows:

o name:
  The image format we are looking for.

o exception:
  Return any errors or warnings in this structure.

## InitializeMagick

> InitializeMagick() initializes the ImageMagick environment.

The format of the InitializeMagick function is:

> InitializeMagick ( const char *path );

A description of each parameter follows:

o path:
  The execution path of the current ImageMagick client.

## IsMagickConflict

Method IsMagickConflict returns true if the image format conflicts with a logical drive (.e.g. X:).

The format of the IsMagickConflict method is:

> unsigned int IsMagickConflict ( const char *magick );

A description of each parameter follows:

o status:
  Method IsMagickConflict returns true if the image format conflicts with a logical drive.

o magick:
  Specifies the image format.

## ListMagickInfo

> ListMagickInfo() lists the image formats to a file.

The format of the ListMagickInfo method is:

> unsigned int ListMagickInfo ( FILE *file, ExceptionInfo *exception );

A description of each parameter follows.

o file:
  A file handle.

o exception:
  Return any errors or warnings in this structure.

## MagickToMime

Method MagickToMime returns the officially registered (or de facto) MIME media-type corresponding to a magick string. If there is no registered media-type, then the string ``image/x-magick'' (all lower case) is returned. The returned string must be deallocated by the user.

The format of the MagickToMime method is:

> char *MagickToMime ( const char *magick );

A description of each parameter follows.

o magick:
  ImageMagick format specification ``magick'' tag.

## RegisterMagickInfo

> RegisterMagickInfo() adds attributes for a particular image format to the list of supported formats. The attributes include the image format name, a method to read and/or write the format, whether the format supports the saving of more than one frame to the same file or blob, whether the format supports native in-memory I/O, and a brief description of the format.

The format of the RegisterMagickInfo method is:

> MagickInfo *RegisterMagickInfo ( MagickInfo *magick_info );

A description of each parameter follows:

o magick_info:
  The magick info.

## SetMagickInfo

Method SetMagickInfo allocates a MagickInfo structure and initializes the members to default values.

The format of the SetMagickInfo method is:

> MagickInfo *SetMagickInfo ( const char *name );

A description of each parameter follows:

o magick_info:
  Method SetMagickInfo returns the allocated and initialized MagickInfo structure.

o name:
  a character string that represents the image format associated with the MagickInfo structure.

## UnregisterMagickInfo

Method UnregisterMagickInfo removes a name from the magick info list. It returns False if the name does not exist in the list otherwise True.

The format of the UnregisterMagickInfo method is:

> unsigned int UnregisterMagickInfo ( const char *name );

A description of each parameter follows:

o status:
  Method UnregisterMagickInfo returns False if the name does not exist in the list otherwise True.

o name:
  a character string that represents the image format we are looking for.
