NAME
pnmmontage - create a montage of portable anymaps
SYNOPSIS
pnmmontage [-?|-help] [-header=headerfile] [-quality=n] [-prefix=prefix] [-0|-1|-2|...|-9]
pnmfile...
DESCRIPTION
Packs images of differing sizes into a minimum-area composite image, optionally producing
a C header file with the locations of the subimages within the composite image.
OPTIONS
-?, -help
Displays a (very) short usage message.
-header
Tells pnmmontage to write a C header file of the locations of the original images
within the packed image. Each original image generates four #defines within the
packed file: xxxX, xxxY, xxxSZX, and xxxSZY, where xxx is the name of the file,
converted to all uppercase. The #defines OVERALLX and OVERALLY are also produced,
specifying the total size of the montage image.
-prefix
Tells pnmmontage to use the specified prefix on all of the #defines it generates.
-quality
Before attempting to place the subimages, pnmmontage will calculate a minimum pos-
sible area for the montage; this is either the total of the areas of all the subim-
ages, or the width of the widest subimage times the height of the tallest subimage,
whichever is greater. pnmmontage then initiates a problem-space search to find the
best packing; if it finds a solution that is (at least) as good as the minimum area
times the quality as a percent, it will break out of the search. Thus, -q 100 will
find the best possible solution; however, it may take a very long time to do so.
The default is -q 200.
-0, -1, ... -9
These options control the quality at a higher level than -q; -0 is the worst qual-
ity (literally pick the first solution found), while -9 is the best quality (per-
form an exhaustive search of problem space for the absolute best packing). The
higher the number, the slower the computation. The default is -5.
NOTES
Using -9 is excessively slow on all but the smallest image sets. If the anymaps differ in
maxvals, then pnmmontage will pick the smallest maxval which is evenly divisible by each
of the maxvals of the original images.
