Being one of the incredibly small few that are currently and
actively programming euphoria in anything other than 256
color mode(dos) or windows, and as one who did a fair amount
of research looking for other modes to program in, i can
(unfortunately) inform you that i know of no library
presently available that allows those color depths.
Under windows, things you create are (from my understanding)
automatically displayed in the resolution/depth the end
user has their windows display set to. mr.cuny's win32lib.ew
has some examples included in his zip file, and that library
has rudimentary support for line drawing. you may wish
to experiment with that library and create some simple
line drawing programs and execute those programs with your
windows display set to different resolutions. some of
us would be quite interested in your findings.
One caveat i see right off the bat:
suppose you say something like:
[pseudcode] line({from}{to}{r,g,b})
well, how each video mode interprets color is quite different.
in trucolor, its simply a length 3 sequence of 0..255 as the
value for each element, corresponding to the intesity of
red green blue... in 32k and 64k its a little different...
it's manipulated on bit level instead of 3 seperate bytes.
15bit i think is 32k and 16 bit is 64k. for 15 bit you have
5 bits for each color, in a packed double byte type format.
i see this as potentially causing bizarre screen effects
when running the same program in different windows display
resolutions/depths... enjoy! *hands out aspirin*
