NAME
pnmindex - build a visual index of a bunch of PNM images
SYNOPSIS
pnmindex
[-size N]
[-across N]
[-colors N]
[-black]
[-title title]
[-quant|-noquant]
pnmfile...
DESCRIPTION
This program is part of Netpbm(1).
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.
If you just want to concatenate some images together, use pnmcat for
that. If you want to make a grid of the same image repeated over and
over, that’s pnmtile.
If you want to take apart the image you generated with pnmindex, use
pamdice or pamcut.
OPTIONS
-size N
The size of each thumbnail. The image is scaled to fit maxi-
mally 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 quan-
tizes 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 option 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.
