pnmindex(1)
NAME
pnmindex - build a visual index of a bunch of anymaps
SYNOPSIS
pnmindex [-size N] [-across N] [-colors N] [-black] [-title T] [-quant|-noquant] pnmfile ...
DESCRIPTION
pnmindex creates an index image containing thumbnail (small) versions
of a bunch of PNM files you supply.
pnmindex labels each thumbnail and, optionally, contains a title.
OPTIONS
- -size N
- 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.
- -across N
- The number of thumbnails in each row. Default is 6.
- -colors N
- 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; nor
- mally it's white and the labels are black lettering on white background, but the -black flag reverses this.
- -title title
- Specifies a title top place at the top of the image. Default is no title.
- -quant Enables quanization (to the number of colors specified by -col
- ors ). Quantization is on by default but you can disable it with -noquant.
- -noquant
- See -quant.
