Question about CGColorSpaceCreateDeviceRGB()
by Chas Spillar

Hello,

I have some code which I did not write which uses the call:

CGColorSpaceCreateDeviceRGB().

Since this software is a server which isn't meant to be rendered on a Mac, I
believe the intent was that no color matching be done.  I think this is what
this call used to do.

This works great on 10.3, but in 10.4 the behavior of this call was
completely changed.

What should be the equivalent call to get the same behavior on 10.4 as this
used to give on 10.3?  I have tried
CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB) but I appear to be
getting color matching and it appears to be slower.

Thank you for your help,

Chas.
