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 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 pnmcomp(1) 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. Should really be in PNM, not PPM.
