       ilbmtoppm - convert an ILBM file into a PPM image

       ilbmtoppm [-ignore<chunkID>] [ -isham | -isnotham | -isehb | -isnotehb | -isdeep | -isnot-
       deep ] [-cmaponly] [-adjustcolors] [-transparent  color]  [-maskfile  filename  [-verbose]

       This program is part of Netpbm(1)

       ilbmtoppm  reads  an IFF ILBM file as input and produces a PPM image as output.	ilbmtoppm
       can handle the following ILBM types:

       o      Normal ILBMs with 1-16 planes.

       o      Amiga Extra_Halfbrite (EHB)

       o      Amiga HAM with 3-16 planes.

       o      24 bit.

       o      Multiplatte (normal or HAM) pictures.

       o      Color map (BMHD + CMAP chunk only, nPlanes = 0).

       o      Unofficial direct color.	1-16 planes for each color component.

       ilbmtoppm uses these ILBM chunks: BMHD, CMAP, CAMG (only HAM & EHB flags used), PCHG, BODY
       unofficial DCOL chunk to identify direct color ILBM.  It ignores these chunks: GRAB, DEST,
       SPRT, CRNG, CCRT, CLUT, DPPV, DRNG, EPSF.  It  ignores,	but  displays  in  verbose  mode,
       these: NAME, AUTH, (c), ANNO, DPI.  It skips chunks whose type it doesn't recognize.

	      Give some information about the ILBM file.

       -ignore chunkID
	      Skip  a  chunk.	chunkID  is  the 4-letter IFF chunk identifier of the chunk to be

       -isham | -isehb
	      Treat the input file as a HAM or Extra_Halfbrite picture, even if these  flags  are
	      not set in the CAMG chunk (or if there is no CAMG chunk).

	      With  this option, ilbmtoppm generates a PPM of the ILBM's color map, not the image

	      ilbmtoppm does the same thing even without -cmaponly if the ILBM is  a  pure  color
	      map  stream  (it	has  a bitmap header with an nplanes value of zero or has no BODY

	      If all colors in the CMAP have a value of less then 16, ilbmtoppm assumes  a  4-bit
	      colormap and gives a warning.  With this option the colormap is scaled to 8 bits.

       The multipalette PCHG BigLineChanges and Huffman decompression code is untested.
