tgatoppm - Man Page
convert TrueVision Targa file to a PPM image
Examples (TL;DR)
- Convert a TrueVision Targa file to a PPM image:
tgatoppm path/to/file.tga > path/to/output.ppm
- Dump information from the TGA header to
stdout
:tgatoppm --headerdump path/to/file.tga > path/to/output.ppm
- Write the transparency channel values of the input image to the specified file:
tgatoppm --alphaout path/to/transparency_file.pgm path/to/file.tga > path/to/output.ppm
- Display version:
tgatoppm -version
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
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.
- --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.
