In messing around with my code I wanted to try and read two pixels from global memory in one read and work on each pixel individually in the kernel. Something like this:
uint2 pixels = imgData[idx];
uchar4 pixelA = pixels.x;
uchar4 pixelB = pixels.y;
which results in the following:
error : no suitable constructor exists to convert from “unsigned int” to “uchar4”
I take pixels.x to be 4 bytes just like uchar4. I must me overlooking some simple, low overhead, way of doing this… How?
Thanks,
Andrei
