Hi Craig,
Are you having to open the TIFF with your own code?
It should be easier than that! Using the built in openAsPicture()
method in RB I am able to open TIFFs with no problem (I believe that
Quicktime might have to be installed on Windows???) . Getting CMYK
data is as simple as getting a Pixel color value and then asking the
color for its C,M, or Y value (as well R, G, B, H, S, & V, too)
if p is your picture then
dim cc as color
dim surf as RGBSurface
dim c, m, y as double
surf = p.RGBSurface
cc = surf.pixel(x, y)
c = cc.cyan
y = cc.yellow
m = cc.magenta
and C, M , & Y will be values from 0 to 1
White would be all of those values equal to 1, Black would be all of
those values equal to 0.
Is that what you meant?

1) Read it in and parse the TIFF? (I've done this.)
2) Use another application to convert it to something that you can
read in with existing RB/QuickTime calls.
