# images:  file(1) magic for image formats (see also "iff", and "c-lang" for
# XPM bitmaps)

# originally from jef@helios.ee.lbl.gov (Jef Poskanzer),
# additions by janl@ifi.uio.no as well as others. Jan also suggested
# merging several one- and two-line files into here.

# little magic: PCX (first byte is 0x0a)

# at 2, byte ImgType must be 1, 2, 3, 9, 10 or 11
#	,32 or 33 (both not observed)
# at 1, byte CoMapType must be 1 if ImgType is 1 or 9, 0 otherwise
#	or theoretically 2-128 reserved for use by Truevision or 128-255 may be used for developer applications
# at 3, leshort Index is 0 for povray, ppmtotga and xv outputs
# `xv' recognizes only a subset of the following (RGB with pixelsize = 24)
# `tgatoppm' recognizes a superset (Index may be anything)

# p M 8 5/6 xx yy zz data...
# Atari ST STAD bitmap is always 640x400, bytewise runlength compressed.
# bytes either run horizontally (pM85) or vertically (pM86). yy is the
# most frequent byte, xx and zz are runlength escape codes, where xx is
# used for runs of yy.
