NAME

tgatoppm – convert TrueVision Targa file into a portable pixmap

SYNOPSIS

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

DESCRIPTION

Reads a TrueVision Targa file as input. Produces a portable pixmap as
output.

OPTIONS

–alphaout=alpha-filename
tgatoppm creates a PGM (portable graymap) file containing the
alpha channel values in the input image. If the input image
doesn’t contain an alpha channel, the alpha-filename file con‐
tains 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 out‐
put to Standard Output and discards the image.

See pnmcomp for one way to use the alpha output file.

–headerdump
Causes the header information to be dumped to stderr.

All options can be abbreviated to their shortest unique prefix.

BUGS

Should really be in PNM, not PPM.
