I've a simple patch, with a single image input, an affine transform
(that flips the image) to a clear and billboard (width 2).
Effectively, because the source image is upside down (coming from
OpenGL) this patch just flips it. The idea is that I pass in a
128x128 image around the mouse cursor, and then replace what I took
with the content of the patch - therefore being able to animate (and
generally mess with) the content under the mouse at any time.
On Leopard it renders just fine.
However on Tiger it's as if the gamma has been bumped up hugely. It's
not quite white, but close. You can still make out the fact that the
image contains the right stuff, it's just the colors are way off.
When compositing, I'm setting up my color spaces using :
The idea being that I want to use the color space setup by the user.
All of my bitmap context creation uses the same color space (well,
they all end up calling this method to get one - they don't share the
same ref).
I've got a whole lot more I could write about creation of pixel
buffers (and their color spaces), etc - but I don't want to cloud this
first question with too much stuff.
Is there anything I should look for here - that's Tiger specific?
I'm at a bit of a loss! Primarily because it works so well on
Leopard.
