       pnmmontage - create a montage of PNM images









       This program is part of Netpbm(1).

       pnmmontage  packs images of differing sizes into a minimum-area compos-
       ite image, optionally producing a C header file with the  locations  of
       the subimages within the composite image.


              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 ouput also includes #defines
              OVERALLX and OVERALLY, which specifies the  total  size  of  the
              montage image.

              Tells  pnmmontage  to  use  the  specified  prefix on all of the
              #defines it generates.

              Before attempting to place the subimages, pnmmontage will calcu-
              late a minimum possible area for the montage; this is either the
              total of the areas of all the subimages, 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 quality (literally pick the first solution  found),
              while  -9  is  the best quality (perform an exhaustive search of
              problem space for the absolute best packing).   The  higher  the
              number, the slower the computation.  The default is -5.


       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
