39.17.7 Other Image Types
For PBM images, specify image type pbm
. Color, gray-scale and monochromatic images are supported. For mono PBM images, two additional image properties are supported.
:foreground foreground
​
The value, foreground
, should be a string specifying the image foreground color, or nil
for the default color. This color is used for each pixel in the PBM that is 1. The default is the frame’s foreground color.
