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.
BUGS
Should really be in PNM, not PPM.
