tgatoppm1

Usage

Overview

This program is part of Netpbm(1) .

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

--headerdump

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