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 ...
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.
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. (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 pa-
mundice for that.
If you want to take apart the image you generated with pnmindex, use
pamdice or pamcut.
The program can generate large temporary files. By default, these go
in directory /tmp, but you can usse the TMPDIR environment variable to
have them somewhere else.
OPTIONS
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see
Common Options ⟨index.html#commonoptions⟩ ), pnmindex recognizes the
following command line 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 ra-
tio. 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 quantization (to the number of colors specified by -col-
ors). Quantization is on by default but you can disable it with
-noquant.
-noquant
See -quant.
