# 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)

# Targa - matches `povray', `ppmtotga' and `xv' outputs
# by Philippe De Muyter <phdm@macqel.be>
# at 2, byte ImgType must be 1, 2, 3, 9, 10 or 11
# at 1, byte CoMapType must be 1 if ImgType is 1 or 9, 0 otherwise
# 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)
