NAME
tgatoppm - convert TrueVision Targa file to a PPM image
SYNOPSIS
tgatoppm
[--alphaout={alpha-filename,-}]
[--headerdump]
tga-filename
All options can be abbreviated to their shortest unique prefix.
DESCRIPTION
This program is part of Netpbm(1).
tgatoppm reads a TrueVision Targa file as input and produces a PPM
image as output.
OPTIONS
--alphaout=alpha-filename
tgatoppm creates a PGM image containing the alpha channel val-
ues in the input image. If the input image doesn’t contain an
alpha channel, the alpha-filename file contains all zero (trans-
parent) alpha values. If you don’t specify --alphaout, tgatoppm
does not generate an alpha file, and if the input image has an
alpha channel, tgatoppm simply discards it.
If you specify - as the filename, tgatoppm writes the alpha out-
put to Standard Output and discards the image.
See pamcomp(1)foronewaytouse the alpha output file.
--headerdump
Causes tgatoppm to dump information from the TGA header to Stan-
dard Error.
