ps.map help
ps.map [-rpe] [input=string] [scale=mapscale] [copies=string] [output=string]

  Flags:

-r  rotate plot

-p  print paper formats ( name width height left right tob bottom(margin) )

-e  create EPS (Encapsulated PostScript) instead of PostScript file

  Parameters:

input=string
    file containing mapping instructions (or use input=- to enter from keyboard)

scale=mapscale
    scale of the output map, e.g. 1:25000 (default: 1panel)

CHANGES BETWEEN VERSION 5.0.x/5.4.x and 6.0

        Devices and ps.select do not exist any more. Paper is defined in paper instruction.

        vpoints are used instead of sites (points are read from vector).

        vector is substituted by vpoints, vlines and vareas.

        Symbols are used instead of icons (different format and directory).

        Map legend can be printed in columns.

DESCRIPTION
ps.map produces an output file containing a PostScript program to produce hardcopy map products on your system's PostScript output device. Output can include a raster map, any number of vector overlays, text labels, and other spatial data.

This program has two distinct modes of operation. The command-line mode requires the user to prepare a file of mapping instructions prior to running ps.map that describes the various spatial and textual information to be printed. The interactive mode (i.e., no command-line arguments) will prompt the user for items to be mapped and does not require the user to prepare a file of instructions (n.b., some options are not used in interactive mode).

The order of commands is generally unimportant but may affect how some layers are drawn. For example to plot vpoints above vareas list the vpoints entry first.

The command line flags are:

-r  Rotate plot 90 degrees.

-p  Print available paper formats.
    ( name width height left right tob bottom(margin) )

-e  Create an EPS (Encapsulated PostScript) plot instead of a PostScript file.

The command-line parameters are:

input=name
    File containing mapping instructions. (or enter input=- to enter from keyboard). These instructions are described in detail below. If omitted, instructions can be piped from stdin.

scale=mapscale
    Scale of the output map, e.g. 1:25000
    Default: Auto-sized to fit page
    This parameter is provided as a convenience. It is identical to the scale mapping instruction described below.

copies=n
    Number of copies to print.
    This parameter is provided as a convenience. It is identical to the copies mapping instruction described below.

output=name
    Name of output the file to contain the PostScript program.

MAPPING INSTRUCTIONS
The mapping instructions allow the user to specify various spatial data to be plotted. These instructions are normally prepared in a regular text file using a system editor. Some instructions are single line instructions while others are multiple line. Multiple line instructions consist of the main instruction followed by a subsection of one or more additional instructions.

One "pixel" is 1 inch / 72.

Instructions that may be included in the subsection under several different main instructions are:

where x y
    The top left corner of the bounding box of the item to be plotted is located x inches from the left edge of the paper and y inches from the top edge of the paper. If x is less than or equal to zero, the default horizontal location is used. If y is less than or equal to zero, the default vertical location is used.

font font name
    The name of the PostScript font. The default is Helvetica.

fontsize font size
    The size of the PostScript font in 1/72 inch. The default is 10.

colortable
Prints the color table for the raster map layer anywhere on the page.
USAGE:    colortable [y|n]
    where x y
    raster raster file
    width table width
    height table height (FP legend only)
    cols table columns
    font font name
    fontsize font size
    color text color
    nodata [y|n]
    end
The color table will display the colors for each raster map layer category value and the category label. If raster is omitted, the colortable defaults to a previously registered raster layer. The default location for the colortable is immediately below any other map legend information, starting at the left margin. The default text color is black. Omitting the colortable instruction would result in no color table. For floating point legends width is width of color band only. height is used only for floating point legend. Adding the nodata n instruction will prevent the "no data" box from being drawn (category based legends only).

Note: Be careful about asking for color tables for raster map layers which have many categories, such as elevation. This could result in the printing of an extremely long color table!!!!!

Another issue is that the color table only includes categories which have a label. If there are only a few categories, you can use r.support to manually add labels. If there are too many categories to do this, you could write a script to add dummy labels to the cats file
(//<;mapset>;/cats/<;mapname>;).

This example would print a color table immediately below any other map legend information, starting at the left margin, with 4 columns:
EXAMPLE:
    colortable y
        cols 4
        width 4
        end

comments
Prints comments anywhere on the page.
USAGE:    comments commentfile
    where x y
    font font name
    fontsize font size
    color text color
    end
The default location is immediately below the last item item printed, starting at the left margin. The default text color is black.

This example prints in blue whatever is in the file veg.comments starting at 1.5 inches from the left edge of the page and 7.25 inches from the top of the page, using a 15/72 inch Helvetica Bold font.
EXAMPLE:
    raster vegetation
    comments veg.comments
    where 1.5 7.25
    font Helvetica Bold
    fontsize 15
    color blue
    end
Presumably, the file veg.comments contain comments pertaining to the raster map layer vegetation, such as "This map was created by classifying a LANDSAT TM image".

copies
Specifies the number of copies to be printed.
USAGE:    copies n
Each page will be printed n times.

eps
Places EPS (Encapsulated PostScript) pictures on the output map.
USAGE:    eps east north
    eps x% y%
    epsfile EPS file
    scale #
    rotate #
    masked [y|n]
    end
The EPS picture location is entered in the main instruction line by giving either the map coordinates or by using percentages of the geographic region. The user must specify full EPS file path epsfile. The user may also specify the scale of the icon (default is 1.0), the rotate i.e. rotation in degrees (default is 0) and whether the point is to be masked by the current mask. for more information on the mask.)

This example would place a EPS file ./epsf/logo.eps at the point (E456000 N7890000). This picture would be rotated 20 degrees clockwise, 3 times bigger than in original file and would not be masked by the current mask.
EXAMPLE:
    eps 456000 7890000
    epsfile ./epsf/logo.eps
    scale 3
    rotate 20
    masked n
    end
Of course, multiple EPS pictures may be drawn with multiple eps instructions.

geogrid
Overlays a geographic grid onto the output map.
USAGE:    geogrid spacing unit
    color color
    numbers # [color]
    font font name
    fontsize font size
    width #
    end
The spacing and spacing unit of the geographic grid is given on the main instruction line. The spacing unit is given as one of d for degrees, m for minutes, and s for seconds. The subsection instructions allow the user to specify the color of the geographic grid lines, whether coordinate numbers should appear on the geographic grid lines, the width of the lines (accepts decimal points [floating points] as well as integers), and if they should appear every grid line (1), every other grid line (2), etc., and what color the numbers should be. The defaults are black grid lines, unnumbered.

NOTE: The geogrid draws grid numbers on the east and south borders of the map.

This example would overlay a blue geographic grid with a spacing of 30 minutes onto the output map. Alternate grid lines would be numbered with yellow numbers.
EXAMPLE:
    geogrid 30 m
    color blue
    numbers 2 yellow
    end

greyrast
Selects a raster map layer for output in shades of grey.
USAGE:    greyrast mapname|list
For each ps.map run, only one raster map layer can be requested (using either the greyrast or the raster instruction).

grid
Overlays a coordinate grid onto the output map.
USAGE:    grid spacing
    color color
    numbers # [color]
    cross cross size
    font font name
    fontsize font size
    end
The spacing of the grid is given (in the geographic coordinate system units) on the main instruction line. The subsection instructions allow the user to specify the color of the grid lines, whether coordinate numbers should appear on the grid lines, and if they should appear every grid line (1), every other grid line (2), etc., and what color the numbers should be. The cross argument draws grid intersection crosses instead of grid lines, with cross size given in geographic coordinate system units. The defaults are black grid lines, unnumbered.

This example would overlay a green grid with a spacing of 10000 meters (for a metered database, like UTM) onto the output map. Alternate grid lines would be numbered with red numbers.
EXAMPLE:
    grid 10000
    color green
    numbers 2 red
    end

group
Selects an RGB imagery group for output.
USAGE:    group groupname
This is similar to raster, except that it uses an imagery group instead of a raster map layer. The group must contain three raster map layers, comprising the red, green and blue bands of the image.

header
Prints the map header above the map.
USAGE:    header
    file header file
    font font name
    fontsize font size
    color text color
    end
If the header instruction or the file sub-instruction is absent, the header will consist of the map TITLE and location, each centered on the page above the map. The default text color is black.

This example prints (in red) whatever is in the file soils.hdr above the map, using a 20/72 inch Courier font.
EXAMPLE:
    header
    file soils.hdr
    font Courier
    fontsize 20
    color red
    end

labels
Selects a labels file for output (see manual entry for v.label ).
USAGE:    labels  labelfile|list
    font font name
    end

NOTE: ps.map can read new option 'ROTATE:' from labels file, which specifies counter clockwise rotation in degrees.

This example would paint labels from the labels file called town.names. Presumably, these labels would indicate the names of towns on the map.
EXAMPLE:
    labels town.names
    end

line
Draws lines on the output map.
USAGE:    line east north east north
    line x% y% x% y%
    color color
    width #
    masked [y|n]
    end
The beginning and ending points of the line are entered on the main instruction. These points can be defined either by map coordinates or by using percentages of the geographic region. The user may also specify line color, width in pixels (accepts decimal points [floating points] as well as integers), and if the line is to be masked by the current mask. for more information on the mask.)

This example would draw a yellow line from the point x=10% y=80% to the point x=30% y=70%. This line would be 2 pixels wide and would appear even if there is a mask.
EXAMPLE:
    line 10% 80% 30% 70%
    color yellow
    width 2
    masked n
    end
Of course, multiple lines may be drawn with multiple line instructions.

mapinfo
Prints the portion of the map legend containing the scale, grid and region information, on or below the map.
USAGE:    mapinfo
    where x y
    font font name
    fontsize font size
    color text color
    end
The default location is immediately below the map, starting at the left edge of the map. The default text color is black.

This example prints (in brown) the scale, grid and region information immediately below the map and starting 1.5 inches from the left edge of the page, using a 12/72 inch Courier font.
EXAMPLE:
    mapinfo
    where 1.5 0
    font Courier
    fontsize 12
    color brown
    end

maploc
Positions the map on the page.
USAGE:    maploc  x y [width height]
The upper left corner of the map will be positioned x inches from the left edge of the page and y inches from the top of the page. If width and height (in inches) are present, the map will be rescaled, if necessary, to fit.

This example positions the upper left corner of the map 2.0 inches from the left edge and 3.5 inches from the top edge of the map.
EXAMPLE:
    maploc 2.0 3.5

maskcolor
Color to be used for mask.
USAGE:    maskcolor  color

outline
Outlines the areas of a raster map layer with a specified color.
USAGE:    outline
    color color
    width width of line in pixels
    end
Distinct areas of the raster map will be separated from each other visually by drawing a border (or outline) in the specified color (default: black). For width the program accepts decimal points [floating points] as well as integers. Note: it is important the user enter the instruction end even if a color is not chosen. (It is hoped that in the future the outline of a different raster map layer other than the one currently being painted may be placed on the map.)

This example would outline the category areas of the soils raster map layer in grey.
EXAMPLE:
    raster soils
    outline
    color grey
    width 2
    end

paper
Specifies paper size and margins.
USAGE:    paper paper name
    point
    height #
    width #
    left #
    right #
    bottom #
    top #
    end
paper may select predefined paper name (a4,a3,a2,a1,a0,us-legal,us-letter,us-tabloid). Default paper size is a4. left, right, bottom and top are paper margins.

EXAMPLE:
    paper a3
    end

EXAMPLE:
    paper
    width 10
    height 10
    left 2
    right 2
    bottom 2
    top 2
    end

point
Places additional points or icons on the output map.
USAGE:    point east north
    point x% y%
    color color
    fcolor color
    symbol symbol group/name
    size #
    masked [y|n]
    end
The point location is entered in the main instruction line by giving either the map coordinates or by using percentages of the geographic region. The user may also specify the point color, the size is size of symbol in point and whether the point is to be masked by the current mask. for more information on the mask.)

This example would place a purple diamond (from icon file diamond) at the point (E456000 N7890000). This diamond would be the the size of a 15 points and would not be masked by the current mask.
EXAMPLE:
    point 456000 7890000
    fcolor purple
    color black
    symbol basic/diamond
    size 15
    masked n
    end
Of course, multiple points may be drawn with multiple point instructions.

psfile
Copies a file containing PostScript commands into the output file.

Note: ps.map will not search for this file. The user must be in the correct directory or specify the full path on the psfile instruction. (Note to /bin/csh users: ~ won't work with this instruction).
USAGE:    psfile filename
This example copies the file "logo.ps" into the output file.
EXAMPLE:
    psfile logo.ps

raster
Selects a raster map layer for output.
USAGE:    raster mapname|list
For each ps.map run, only one raster map layer (or set of layers or imagery group; see below) can be requested. If no raster map layer is requested, a completely white map will be produced. It can be useful to select no raster map layer in order to provide a white background for vector images.

Note that an imagery group selected with the group option, or a set of three raster layers selected with the rgb option, count as a raster map layer for the purposes of the preceding paragraph.

This example would paint a map of the raster map layer soils.
EXAMPLE:
    raster soils

read
Provides ps.map with a previously prepared input stream.
USAGE:    read previously prepared UNIX file
Mapping instructions can be placed into a file and read into ps.map.

Note: ps.map will not search for this file. The user must be in the correct directory or specify the full path on the read instruction. (Note to /bin/csh users: ~ won't work with this instruction).

This example reads the UNIX file pmap.roads into ps.map. This file may contain all the ps.map instructions for placing the vector map layer roads onto the output map.
EXAMPLE:
    read pmap.roads
The user may have created this file because this vector map layer is particularly useful for many ps.map outputs. By using the read option, the user need not enter all the input for the vector instruction, but simply read the previously prepared file with the correct instructions.

rectangle
Draws rectangle on the output map.
USAGE:    rectangle east north east north
    rectangle x% y% x% y%
    color color
    fcolor fill color
    width #
    masked [y|n]
    end
The two corners of the rectangle are entered on the main instruction. These points can be defined either by map coordinates or by using percentages of the geographic region. The user may also specify line color, fill color fcolor, width in pixels (accepts decimal points [floating points] as well as integers), and if the rectangle is to be masked by the current mask. for more information on the mask.)

This example would draw a yellow rectangle filled by green from the point x=10% y=80% to the point x=30% y=70%. This line would be 2 pixels wide and would appear even if there is a mask.
EXAMPLE:
    rectangle 10% 80% 30% 70%
    color yellow
    fcolor green
    width 2
    masked n
    end
Of course, multiple rectangles may be drawn with multiple rectangle instructions.

region
Places the outline of a smaller geographic region on the output.
USAGE:    region regionfile|list
    color color
    width #
    end
Geographic region settings are created and saved using g.region . The ps.map region option can be used to show an outline of a smaller region which was printed on a separate run of ps.map on other user-created maps.

The user can specify the color and the width in pixel units (accepts decimal points [floating points] as well as integers) of the outline. The default is a black border of one pixel width.

This example would place a white outline, 2 pixels wide, of the geographic region called fire.zones onto the output map. This geographic region would have been created and saved using g.region .
EXAMPLE:
    region fire.zones
    color white
    width 2
    end

rgb
Selects three raster map layers for output as an RGB color image.
USAGE:    rgb red green blue
This is similar to raster, except that it uses three raster map layers instead of a single layer. The three layers are composed to form a color image, similar to d.rgb.

For each layer, only one of the components of the layer's color table is used: the red component for the red layer, and so on. This will give the desired result if all of the layers have a grey-scale color table, or if each layer's color table uses the hue appropriate to the layer.

scale
Selects a scale for the output map.
USAGE:    scale scale
The scale can be selected either as:

a relative ratio, e.g. 1:25000;

an absolute width of the printed map, e.g. 10 inches;

the number of printed paper panels, e.g. 3 panels
    .I (at the present time, only 1 panel is supported);

the number of miles per inch, e.g. 1 inch equals 4 miles.

This example would set the scale of the map to 1 unit = 25000 units.
EXAMPLE:
    scale 1:25000

scalebar
Draws a scalebar on the map.
USAGE:    scalebar [f|s]
    where x y
    length scale length
    height scale height
    segment no. segments
    numbers #
    fontsize font size
    end
Draw one of two types of scales bars. Fancy (f) draws alternating black and white scale boxes. Simple (s) draws a plain line scale. The default type is fancy. The subsection instructions allow the user to set where the scalebar is placed, the length of the scalebar (in geographic coordinate system units), the height of the scalebar in inches, and the number of segments (or tics for simple). The number of annotations numbers every n-th segment. The scalebar length is the only required argument. The defaults are a fancy scalebar with 4 segments, each segment labeled, and a height of 0.1 inches. The default location is 2 inches from the top of the page and halfway across.

NOTE: The scalebar is centered on the location given.

This example draws a simple scalebar 1000 meters (for a metered database, like UTM) long, with tics every 200 meters, labeled every second tic. The scalebar is drawn 5 inches from the top and 4 inches from the left and is 0.25 inches high.
EXAMPLE:
    scalebar s
    where 4 5
    length 1000
    height 0.25
    segment 5
    numbers 2
    end

setcolor
Overrides the color assigned to one or more categories of the raster map layer.
USAGE:    setcolor cat(s) color
This example would set the color for categories 2,5 and 8 of the raster map layer watersheds to white and category 10 to green. (NOTE: no spaces are inserted between the category values.)
EXAMPLE:
    raster watersheds
    setcolor 2,5,8 white
    setcolor 10 green
Of course, setcolor can be requested more than once to override the default color for additional categories. More than one category can be changed for each request by listing all the category values separated by commas (but with no spaces).

text
Places text on the map.
USAGE:    text  east north text
    text x% y% text
    font fontname
    color color|none
    width #
    hcolor color|none
    hwidth #
    background color|none
    border color|none
    size #
    ref reference point
    xoffset #
    yoffset #
    opaque [y|n]
    end
The user specifies where the text will be placed by providing map coordinates or percentages of the geographic region map. The text follows these coordinates on the same instruction line. More than one line of text can be specified by notating the end of a line with \n (e.g. USA\nCERL).

The user can then specify various text features:

font: cyrilc gothgbt gothgrt gothitt greekc greekcs greekp greeks italicc italiccs italict romanc romancs romand romans romant scriptc scripts (The default font is romans);

color (see NAMED COLORS);

width of the lines used to draw the text to make thicker letters (accepts decimal points [floating points] as well as integers);

size as the vertical height of the letters in meters on the ground (text size will grow or shrink depending on the scale at which the map is painted). If no size is given, a default text size will be used;

the highlight color (hcolor) and the width of the highlight color (hwidth);

the text-enclosing-box background color; the text box border color;

ref. This reference point specifies the text handle - what part of the text should be placed on the location specified by the map coordinates. Reference points can refer to: [lower|upper|center] [left|right|center] of the text to be printed;

yoffset, which provides finer placement of text by shifting the text a vertical distance in pixels from the specified north. The vertical offset will shift the location to the south if positive, north if negative;

xoffset, which shifts the text a horizontal distance in pixels from the specified east The horizontal offset will shift the location east if positive, west if negative;

whether or not the text should be opaque to vectors. Entering no to the opaque option will allow the user to see any vectors which go through the text's background box. Otherwise, they will end at the box's edge.

The following example would place the text SPEARFISH LAND COVER at the coordinates E650000 N7365000. The text would be a total of 3 pixels wide (2 pixels of red text and 1 pixel black highlight), have a white background enclosed in a red box, and be 500 meters in size. The lower right corner of the text would be centered over the coordinates provided. All vectors on the map would stop at the border of this text.
EXAMPLE:
    text 650000 7365000 SPEARFISH LAND COVER
    font romand
    color red
    width 2
    hcolor black
    hwidth 1
    background white
    border red
    size 500
    ref lower left
    opaque y
    end

vareas
Selects a vector map layer for output.
USAGE:    vareas vectormap
    layer # (layer number used with cats/where option)
    cats list of categories (e.g. 1,3,5-7)
    where SQL where statement like: vlastnik = 'Cimrman'
    masked [y|n]
    color color
    fcolor color
    width #
    cats area categories
    label label in legend
    lpos position in legend
    pat pattern file
    pwidth #
    scale #
    end
The user can specify:

color - color of the vector lines or area boundaries;

fcolor - the area fill color.

width - width of the vectors lines or area boundaries in pixels (accepts decimal points [floating points] as well as integers);

masked - whether or not the raster map layer is to be masked by the current mask; for more information on the mask)

cats - which categories should be plotted (default is all);

label - for description in vlegend. Default is: map(mapset);

lpos - position vector is plotted in legend. If lpos is 0 then this vector is omitted in legend. If more vectors used the same lpos then their symbols in legend are merged and label for first vector is used.

pat - full path to pattern file. Pattern file contains header and simple PS commands. It is similar to EPS but more limited, that means that each pattern file is EPS file but EPS files are not usually usefull as pattern files because contain restricted commands. Color and width of patterns is set by acolor and pwidth until it is overwritten in pattern file. Currently the only way to create pattern file is text editor. Example of pattern file:
%!PS-Adobe-2.0 EPSF-1.2
%%BoundingBox: 0 0 10 10
newpath
5 0 moveto
5 10 lineto
stroke

scale - pattern scale

pwidth - pattern line width, width is used by pattern until the width is overwritten in pattern file.

EXAMPLE:
    vareas forest
    color blue
    width 1
    masked y
    cats 2,5-7
    end

vlines
Selects a vector map layer for output.
USAGE:    vlines vectormap|list
    type lines and/or boundaries
    layer # (layer number used with cats/where option)
    cats list of categories (e.g. 1,3,5-7)
    where SQL where statement like: vlastnik = 'Cimrman'
    masked [y|n]
    color color
    width #
    cwidth #
    hcolor color
    hwidth #
    offset #
    coffset #
    ref left|right
    style 0-9
    label label
    lpos #
    end
The user can specify:

color - color of the vector lines or area boundaries;

width - width of the vectors lines or area boundaries in pixels (accepts decimal points [floating points] as well as integers);

cwidth - width of the vectors lines. If cwidth is used then width of line is equal to cwidth * category value and width is used in legend;

hcolor - the highlight color for the vector lines;

hwidth - the width of the highlight color in pixels;

offset (experimental) - offset for the vectors lines in pixels for plotting parallel lines in distance equal to offset (accepts positive or negative decimal points). Useful to print streets with several parallel lanes;

coffset (experimental) - offset for the vectors lines. If coffset is used then offset of line is equal to coffset * category value and offset is used in legend;

ref (experimental) - line justification.

masked - whether or not the raster map layer is to be masked by the current mask; for more information on the mask);

style - the line style allows the vectors to be dashed in different patterns. This is done by typing a series of numbers (0's and 1's) in a desired sequence or pattern. Blanks and non-digit characters are recognized as 0's. Using 0 would allow the colors of the raster map layer (or the background color if no raster map layer was selected) to show through;

cats - which categories should be plotted (default is all);

label - for description in vlegend. Default is: map(mapset);

lpos - position vector is plotted in legend. If lpos is 0 then this vector is omitted in legend. If more vectors used the same lpos then their symbols in legend are merged and label for first vector is used.

EXAMPLE:
    vlines streams
    color blue
    width 2
    hcolor white
    hwidth 1
    masked y
    cats 2
    label Streams - category 2
    end

vpoints
Selects vector point data to be placed on the output map
USAGE:    vpoints vector
    type point or/and centroid
    layer # (layer number used with cats/where option)
    cats list of categories (e.g. 1,3,5-7)
    where SQL where statement like: vlastnik = 'Cimrman'
    masked [y|n]
    color color
    fcolor color
    width #
    eps epsfile
    symbol symbol group/name
    size #
    cats list of categories
    label legend label
    lpos position in legend
    end
The user may specify the the color of the sites (see section on NAMED COLORS below); the eps Encapsulated Postscript file to be used to represent the presence of a site; If $ is used in EPS file path it is replaced by category number. the size of the icon (number of times larger than the size it is in the icon file); the rotate in degrees for clockwise rotation for EPS files;
EXAMPLE:
    vpoints windmills
    color blue
    symbol mills/windmill
    size 10
    end

verbose
Changes the amount of talking ps.map will do.
USAGE: verbose [0|1|2]
A higher value implies more chatter. The default is 2. This example sets the amount of chatter to a minimum.
EXAMPLE:
    verbose 0

vlegend
Prints the portion of the map legend containing the vector information, on or below the map.
USAGE:    vlegend
    where x y
    font font name
    fontsize font size
    width width of color symbol
    cols number of columns to print
    end
The default location is immediately below the legend containing the scale, grid and region information, starting at the left edge of the map. If the where instruction is present and y is less than or equal to zero, the vector legend will be positioned immediately below the map, starting x inches from the left edge of the page.

width is the width in inches of the color symbol (for areas) in front of the legend text. The default is 1/24 * fontsize inches. cols is the number of columns to split the legend into. The default is one column. The maximum number of colums is 10, or equal to the number of legend entries if there are less than 10 entries.

This example prints the vector legend immediately below the map and starting 4.5 inches from the left edge of the page, using a 12/72 inch Helvetica font.
EXAMPLE:
    vlegend
    where 4.5 0
    font Courier
    fontsize 12
    end

end
Terminates input and begin painting the map.
USAGE:    end

  ps.map input=spear.soils output=soils.ps
raster soils
outline
   color black
   width 1
   end
comments soil.cmt
   where 1 6
   font Helvetica
   end

end

INTERACTIVE MODE
If the user simply enters ps.map without arguments, then a simple prompting session occurs. Some, but not all of the non-interactive requests are available at this level.

NOTES
The user can specify negative values for position of EPS-files in ps.map to move them outside the current region (to position a barscale or other legend entries).
