NAME
tgatoppm - convert TrueVision Targa file to a PPM image
SYNOPSIS
tgatoppm [--alphaout={alpha-filename,-}] [--headerdump] tga-filename
DESCRIPTION
This program is part of Netpbm(1)
tgatoppm reads a TrueVision Targa file as input and produces a PPM image as output.
OPTIONS
All options can be abbreviated to their shortest unique prefix.
| --alphaout=alpha-filename | |
| tgatoppm creates a PGM image containing the alpha channel
values in the input image. If the input image doesn’t contain an
alpha channel, the alpha-filename file contains all zero
(transparent) 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 output to Standard Output and discards the image. See pamcomp(1) for one way to use the alpha output file.

| --headerdump | |
| Causes tgatoppm to dump information from the TGA header to
Standard Error.
