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 image as output.

OPTIONS

All options can be abbreviated to their shortest unique prefix.

*–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) for one way to use the alpha output file.

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