| I managed to get colour slides out of RAGS. I think I just displayed
the image in RAGS, then used UTOX 'screen capture' mode to
grab an image and convert it to sixel format (which is what I needed
for the LJ250).
This is pretty labour-intensive stuff, so I wouldn't suggest doing it
to make a large presentation.

| I have been using RAGS to produce colour slides, VOYER to display them on
the screen and MOPS (/TYPE=SIX) to produce hardcopy output to an LJ250.
Apart from the fact the LJ250 colours are only rough approximations of the
original display colours, I have not had any problem with colour.
Make sure that you are using a version of RAGS (MOPS, VOYER) that supports
colour output. I believe the first version to support colour output is
dated 17-May-1989.

| The new round of CDA viewers (available with DECwindows V2 and also
bundled with CDA Converter Library V1, DECwrite V1, and DECdecision V1)
will do full color (text, graphics, and images). And, as of DECwindows
V2, I believe the built-in screen dump will do color and will support
the LJ250.
So, as those are all bundled items, all you need is come color creation
software and have it write out DDIF.

| As Mark said in .3 the CDA viewer can do a VERY nice job of displaying color
DDIF. The nicest of these I have seen to date are CGM converted files to DDIF.
However, at the moment, the viewer is too slow in reproducing CGM DDIF files
for presentation purposes, unless you did had, say three-four viewers running in
parallel, all place at the same location on the screen. Then, when you wanted
to see the "next" slide, you would just push the top one to the bottom of the
viewing stack and the next would would appear, already completed with its
drawing task. This drawing speed, I've been reassured by the project leader,
some work is being done to improve it.
If you don't need SUPER smooth shading, which you will get with the CGM
convertor, you can spend a little time getting screen dumps from the session
manager, of the CDA viewer, after it has completed a beautiful, but slow draw,
and then use the screen images in the cda viewer. These are displayed in
very real time (at least on my 3200) but look a little "choppy". I think you
will need the V2 screen capture since I don't think V1 could capture color
screen images, only UTOX could.
