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 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.
