ilbmtoppm(1)			     General Commands Manual			     ilbmtoppm(1)

NAME
       ilbmtoppm - convert an ILBM file into a portable pixmap

SYNOPSIS
       ilbmtoppm [-verbose] [-ignore<chunkID>] [-isham|-isehb] [-adjustcolors] [ILBMfile]

DESCRIPTION
       Reads  an  IFF  ILBM file as input.  Produces a portable pixmap as output.  Supported ILBM
       types are:

       Normal ILBMs with 1-16 planes.

       Amiga Extra_Halfbrite (EHB)

       Amiga HAM with 3-16 planes.

       24 bit.

       Multiplatte (normal or HAM) pictures.

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

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

       Chunks used:
	      BMHD, CMAP, CAMG (only HAM & EHB flags used), PCHG, BODY unofficial DCOL	chunk  to
	      identify direct color ILBM

       Chunks ignored:
	      GRAB, DEST, SPRT, CRNG, CCRT, CLUT, DPPV, DRNG, EPSF

       Other chunks (ignored but displayed in verbose mode):
	      NAME, AUTH, (c), ANNO, DPI

       Unknown chunks are skipped.

OPTIONS
       -verbose
	      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
	      skipped.

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

       -adjustcolors
	      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.

BUGS
       The multipalette PCHG BigLineChanges and Huffman decompression code is untested.
