Thread-topic: CoreImage Kernel - image with negative components?
Hi,
Sorry if this is the wrong list, but I can't see one for Apple's
CoreImage kernel language...
I've written a CIKernel in QC that does some physics calculations and
I'm storing the simulation's physical attributes in the different colour
components. However, some of these values may need to go negative - what
happens to the output image if some of the pixels contain negative
values in the ARGB components, or the component values go above 1.0? Are
the component values clipped only when the image is rendered, or does
the clipping happen on write?
Thanks,
oli
