Web6 de jun. de 2014 · It means bytes in a row of pixels including any padding. So an image could be 510 pixels in width and rounded up to 512 pixels. The stride would be 512 * bit depth of the image’s format. You could also have stride in pixels. in which case the stride would be 512 pixels. Pitch is a little more vague, but typically could be interchangeable … http://man.opencl.org/clEnqueueMapImage.html
