Hi Folks,
A friend (supposedly) reminded me I needed to update one
of my web pages to reflect the fact that in IDL 6.4 the
Z-graphics buffer can be configured as a 24-bit device, in addition
to the 8-bit device it has always been in the past. (The
actual Z-buffer remains a 16-bit buffer, as it was before.)
In the course of updating the page, I realized none of my
color tools worked in the 24-bit Z-buffer, which meant I
had to update those, too. Aaahhh! Which meant my evening hasn't
exactly gone as planned. (We took my youngest over to the
University and deposited him in the dorm his mother and I
first met in 34 years ago, and on our 29th wedding anniversary
to boot! I had to promise to NOT tell stories as we walked
though the dorm, remembering how much fun dorm life was all
those years ago. ;-)
Anyway, the wife has gone to bed and my plans for some wine
on the porch and some..., well, you know, is shot. :-(
Thought I would let you know, however, that new versions
of TVIMAGE, TVSCALE, TVREAD, and FSC_COLOR are available
and all work with the 24-bit Z-buffer.

Cheers,

P.S. To the person who implemented the 24-bit Z-buffer,
I agree that GET_PIXEL_DEPTH is better than GET_VISUAL_DEPTH,
but it makes it hard to write elegant and compact code, is all
I'm saying. :-(
