# pcdovtoppm - generate a single PPM file from a PCD overview file
#
# Based on pnmindex (PBMPLUS), which was written by Jef Poskanzer,
# this script makes also use of hpcdtoppm, written by Hadmut Danisch.
#
# Formerly called Pcdindex.
#
# A similar result can be achieved by using "hpcdtoppm -Overview"
# followed by "pnmindex -black" on the generated PPM images.
# This shell just makes it more convenient and transparent to
# convert from one PCD to one PPM overview file.
#
# Additional options (compared to pnmindex) are -maxwidth and
# -font <font>. See "man pbmtext" on how to create your own font.
#
# Pieter S. van der Meulen, 1992.
# Rewritten in sh by Steve McIntyre <93sam@debian.org>, 2001
# You may want to change the default values in the next 6 lines:
maxwidth=1152 # maximum width of the index image
size=192 # make the images about this big
across=6 # show this many images per row
colors="noquant" # maximum amount of colors or noquant (no quantization)
back="-black" # default background color
font=" " # default font or none (pbmtext's internal font)
