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 im-
age as output.
OPTIONS
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see
Common Options ⟨index.html#commonoptions⟩ ), tgatoppm recognizes the
following command line options:
All options can be abbreviated to their shortest unique prefix.
--alphaout=alpha-filename
tgatoppm creates a PGM image containing the transparency chan-
nel values in the input image. If the input image doesn't con-
tain a transparency channel, the alpha-filename file contains
all zero (transparent) transparency values. If you don't spec-
ify --alphaout, tgatoppm does not generate an alpha file, and if
the input image has a transparency channel, tgatoppm simply dis-
cards it.
If you specify - as the filename, tgatoppm writes the transpar-
ency output to Standard Output and discards the image.
See pamcomp(1) for one way to use the transparency output file.
--headerdump
Causes tgatoppm to dump information from the TGA header to Stan-
dard Error.
