Specifying an Image Map
The syntax for an image_map is:
IMAGE_MAP:
pigment {
image_map {
[BITMAP_TYPE] "bitmap[.ext]"
[IMAGE_MAP_MODS...]
}
[PIGMENT_MODFIERS...]
}
IMAGE_MAP:
pigment {
image_map {
FUNCTION_IMAGE
}
[PIGMENT_MODFIERS...]
}
BITMAP_TYPE:
gif | tga | iff | ppm | pgm | png | jpeg | tiff | sys
IMAGE_MAP_MOD:
map_type Type | once | interpolate Type |
filter Palette, Amount | filter all Amount |
transmit Palette, Amount | transmit all Amount
FUNCTION_IMAGE:
function I_WIDTH, I_HEIGHT { FUNCTION_IMAGE_BODY }
FUNCTION_IMAGE_BODY:
PIGMENT | FN_FLOAT | pattern { PATTERN [PATTERN_MODIFIERS] }
After the optional BITMAP_TYPE keyword is a string expression containing the name of a bitmapped image file of the specified type. If the BITMAP_TYPE is not given, the same type is expected as the type set for output.
