elisp: Other Image Types
37.17.7 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.
‘:background BACKGROUND’
The value, BACKGROUND, should be a string specifying the image
background color, or ‘nil’ for the default color. This color is
used for each pixel in the PBM that is 0. The default is the
frame’s background color.
The remaining image types that Emacs can support are:
GIF
Image type ‘gif’. Supports the ‘:index’ property.
Multi-Frame Images.
JPEG
Image type ‘jpeg’.
PNG
Image type ‘png’.
SVG
Image type ‘svg’.
TIFF
Image type ‘tiff’. Supports the ‘:index’ property.
