I remeber the AT&T TARGA. Output was to a RGB

wrote a converter to the Amiga IFF and PC GIF, but I can't find the
source any more.
I worked on one of those; some small investigation showed that the .TGA
files were 16-bit raw with a header (ie. no compression). Can't
remember if it was 5-5-5 or 5-6-5 but would be very easy to test based
on the output of the converter...
I just pulled an image formats spec book off the shelf and I'm surprised at
how capable Targa format actually was; image formats could be colour mapped or
direct colour, and colour entries could be 15, 16, 24 or 32 bits in length. (I
used to use it in connection with 3D-Studio work and raytracing output, but
I'd never looked at the details of the format itself)
The format will support RLE compression, as well as developer extensions and
embedded thumbnail images. Version 1.0 format was released back in 1984, v2.0
was 1989.
I'm surprised it isn't more common today, to be honest (although I suppose it
doesn't do anything that TIFF doesn't do).
