BMP2TGA.EXE is a DOS command line utility we've included that
will convert either a 16 or 256 color BMP file to a Type 1
Targa file.

This is a very simple utility, and is not full of bells and
whistles.  The intent is simply to give the POPOUT-PRO user an
easy mechanism to convert 256-color BMP images into Targa
format, so that they will be accepted by POPOUT-PRO as a
valid Depth File image.

All that aside, here's how the utility works:

If the BMP file is 16 color, BMP2TGA expects that the 16 colors
be the same colors defined in POPOUT.PAL.  These colors are listed
in the POPOUT.HLP help file.  These 16 colors will be converted
to shades of grey in the resultant targa file.  Colors other than
these 16 will be translated to black in the targa file.  Remember,
there's really no need to do this; POPOUT-PRO will accept the 16-color
BMP file as a Depth File just as easily as it will accept the
Targa file.

If the BMP file is 256 color, the resultant targa file is
suitable either as a POPOUT-PRO Depth File or Colorfield File.
Be careful with this.  Since POPOUT-PRO will accept Type 1 Targa
files as valid Depth Images, you may be temped to take any
old 256-color BMP file and convert it.  This doesn't mean
that you'll like the results.  Remember, your generic old
256-color images do not contain any depth information, and
POPOUT-PRO will not therefore be able to generate a stereogram
with a meaningful content.

The usage of the utility is:
bmp2tga input_bmp output_tga

where input_bmp is the name of the 16 or 256 color BMP you 
 want to convert, and
where output_tga is the name of the Type 1 TGA file that
 you want bmp2tga to create.
