pnmindex - build a visual index of a bunch of PNM images
You can use the minimum unique abbreviation of the options. You can use two hyphens
instead of one. You can separate an option name from its value with white space instead
of an equals sign.
This program is part of Netpbm(1)
pnmindex creates an index image containing thumbnail (small) versions of a bunch of PNM
files you supply. (Akin to a photographic 'contact sheet.'
pnmindex labels each thumbnail and, optionally, contains a title.
If you just want to concatenate some images together in a grid, use pamundice for that.
If you want to take apart the image you generated with pnmindex, use pamdice or pamcut.
The size of each thumbnail. The image is scaled to fit maximally inside a N x N
pixel box without changing its aspect ratio. Default is 100.
The number of thumbnails in each row. Default is 6.
The maximum number of colors allowed in the overall image. If it would otherwise
have more colors than these, pnmindex quantizes the result. The default is 256.
However, this value is meaningless if you specify the -noquant option.
-black This controls the color of the padding between the images; normally it's white and
the labels are black lettering on white background, but the -black option reverses
Specifies a title top place at the top of the image. Default is no title.
-quant Enables quantization (to the number of colors specified by -colors). Quantization
is on by default but you can disable it with -noquant.
