Can't you make this feather on the actual image? You could use a black and white image as alpha using pix_takealpha to do this. But my english is not that good, i may not be anderstanding what you're trying to do.

Hello,

I am working on a patch with five rectangles in GEM with live video input. These rectangles are long and horizontal, stacked on top of each other. I would like to feather the horizontal edges of these rectangles, is there a way to do this with pix_convolve? I do not need to detect any edges within the image itself, only the rectangle.

Thanks, Michael
