.NAME
psiescape.h -- Define the special GIO escape instructions.
.ih
DESCRIPTION
The following escape instructions are defined for the PostScript GKI
Interpreter:
PS_CODE - Send the raw PostScript code to the output.
PS_IMAGE_RED_LUT - Download a new lookup table for the Red component
of an image.
PS_IMAGE_GREEN_LUT - Download a new lookup table for the Green component
of an image.
PS_IMAGE_BLUE_LUT - Download a new lookup table for the Blue component
of an image.
PS_GR_RED_LUT - Download a new lookup table for the Red component
for the graphics.
PS_GR_GREEN_LUT - Download a new lookup table for the Green component
for the graphics.
PS_GR_BLUE_LUT - Download a new lookup table for the Blue component
for the graphics.
PS_ROMAN_FONT - Specify a new font for the normal font.
PS_GREEK_FONT - Specify a new font for the greek font.
PS_ITALIC_FONT - Specify a new font for the italic font.
PS_BOLD_FONT - Specify a new font for the bold font.
PS_VARIABLE_SPACE - Change whether characters are mono-spaced or
variable-spaced.
PS_DASH, PS_DOT,
PS_SPACE - Change the sizes of a dash, a dot, and the space
between them.
PS_FILL_PATTERN - Add/change fill patterns.
The size of the instruction array should have the following minimums:
- For the PS_CODE instruction, the array should be the length of the string
being passed.
- The size of each image LUT array is PS_IMAGE_LUT_SIZE.
- The size of each graphics LUT array is PS_GR_LUT_SIZE.
- The font arrays should be the length of the string containing the name
of the font to use.
- For the PS_VARIABLE_SPACE, the size is PS_VARIABLE_SPACE_SIZE.
- For PS_FILL_PATTERN, the size is PS_FILL_SIZE.
