1120.0. "Creating color slides and displaying them" by AIAG::KANNAN () Mon Jul 17 1989 15:03

    About a year ago I used to produce color slides that went along with some
    demos. This was when I was using VMS 4.7 and UIS. I used to
    create color slides using SIGHT and display them on the screen using
    RENDER.
    
    Now I am running VMS 5.1 and DECWindows. I need to do the same thing
    now; creating color slides and displaying them. I've tried different
    combinations of creation tools and display tools. None of them seem to
    recreate color information. Either they are lost in the creation tool
    or in the display portion.

1120.1sort of...MU::PORTERRightward Ho!Mon Jul 17 1989 20:4010
    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.
    
                   

1120.2RAGS works fineGVAADG::RITCHIEA Load of Old CobolersTue Jul 18 1989 04:4612
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.

1120.3Bundled CDA viewer does full colorDDIF::BRAMHALLMark Bramhall, CDA architectureTue Jul 18 1989 12:219
    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.

1120.4CDA viewer still needs some speed up workDCC::ALDENKen AldenWed Jul 19 1989 04:3623
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.

Cheers,
-Ken


1120.5RAGS + VOYER seems to be the best choice for meAIAG::KANNANWed Jul 19 1989 09:017
    Thanks everyone for your very helpful input. For my purposes,
    RAGS + VOYER seems to be just the thing I was looking for. VOYER
    puts up slides very fast.
