tgatoppm - convert TrueVision Targa file to a PPM image

tgatoppm

[--alphaout={alpha-filename,-}]

[--headerdump]

tga-filename

All options can be abbreviated to their shortest unique prefix.

This program is part of netpbm(1).

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

--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) foronewaytouse the alpha output file.

--headerdump

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