ilbmtoppm [-verbose] [-ignore<chunkID>] [-isham|-isehb] [-adjustcolors]
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.
Multiplatte (normal or HAM) pictures.
Color map (BMHD + CMAP chunk only, nPlanes = 0).
Unofficial direct color.
1-16 planes for each color component.
BMHD, CMAP, CAMG (only HAM & EHB flags used), PCHG, BODY unoffi-
cial DCOL chunk to identify direct color ILBM

Give some information about the ILBM file.
Skip a chunk. <chunkID> is the 4-letter IFF chunk identifier of
the chunk to be skipped.

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