tgatoppm - Man Page

convert TrueVision Targa file to a PPM image

Examples (TL;DR)


tgatoppm [--alphaout={alpha-filename,-}] [--headerdump] tga-filename


This program is part of Netpbm(1).

tgatoppm reads a TrueVision Targa file as input and produces a PPM image as output.


In addition to the options common to all programs based on libnetpbm (most notably -quiet, see Common Options ), tgatoppm recognizes the following command line options:

All options can be abbreviated to their shortest unique prefix.


tgatoppm creates a PGM image containing the transparency channel values in the input image.  If the input image doesn't contain a transparency channel, the alpha-filename file contains all zero (transparent) transparency values.  If you don't specify --alphaout, tgatoppm does not generate an alpha file, and if the input image has a transparency channel, tgatoppm simply discards it.

If you specify - as the filename, tgatoppm writes the transparency output to Standard Output and discards the image.

See pamcomp(1) for one way to use the transparency output file.


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