3# images:  file(1) magic for image formats (see also "iff")
4#
5# originally from jef@helios.ee.lbl.gov (Jef Poskanzer),
6# additions by janl@ifi.uio.no as well as others. Jan also suggested
7# merging several one- and two-line files into here.

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

11# Targa - matches `povray', `ppmtotga' and `xv' outputs
12# by Philippe De Muyter <phdm@macqel.be>
13# at 2, byte ImgType must be 1, 2, 3, 9, 10 or 11
14# at 1, byte CoMapType must be 1 if ImgType is 1 or 9, 0 otherwise
15# at 3, leshort Index is 0 for povray, ppmtotga and xv outputs
16# `xv' recognizes only a subset of the following (RGB with pixelsize = 24)
17# `tgatoppm' recognizes a superset (Index may be anything)
