tgatoppm - convert TrueVision Targa file into a portable pixmap

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

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

• --alphaout= alpha-filename
      .B 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-filenamefile contains all zero (transparent) alpha values. If you don't specify

R --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

R 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.

UGS Should really be in PNM, not PPM.
