Thanks Dave, I'll take a look.

With respect to CMYK, what's so cool about CMYK, while having the RGBA
Ken?
1) If I use RGBA, then to draw in all four channels, I'll have to use
the drawing routines twice--once for RGB and again for A.
2) It doesn't allow for CMYKA.
3) There is no native way to write a CMYK(A) graphics file from RGBA in
RB.
I need to write an app that can specify directly the CMYK percentages
for each drawn element, so any method that relies on converting RGB to
CMYK is not going to work.
I'm still on RB 5.2.4, so I'll need to upgrade if I go forward with
this. Since I have not seen the newer versions of RB, I'd like to ask a
couple of specific questions about it.
1) Is there a grayscale graphics object now? In other words, if I need
to create a second graphics object in order to draw the extra channels,
I'd like to do so without wasting memory that I don't really need. In
5.2.4 I have to create a second RGBA object, but I only use the A
channel.
2) If I bring the graphics object(s) into a plugin, is there going to
be a speed advantage over simply doing my drawing from native code? In
other words, I would bring my object into the plugin, draw into RGB (as
CMY) and then draw the same thing again into A (as K). If needed, draw
yet again into A of a second object (as A). All of this will later be
organized into a memory block to write to TIFF, or some other format,
using my own file writing code (since I can't write CMYK files from
RB). Again, the question here is whether you think there would be any
speed advantage to doing this in a plugin rather than in native RB
code?
3) I've not used the vector drawing in RB but I've seen a lot of
discussion about it on the NUG-list. Is this the same as the vector3D
that I've seen in 5.2.4, or is this a new type of graphics object?
Thanks to everyone else who has responded. I appreciate the input.
