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.
