Ragzouken, I have opted for your solution for now. Thank you. My approach turned out to be more difficult to use, especially because line angle is constantly changing.

Love is indeed all-powerful. I have achieved desired function by rotating a Canvas' coordinate system around my line's origin point and drawing on it the image with the needed linear area now horizontal. I actually needed this to take a sample of a racetrack image, simulating a line scan camera. Scr...

Hi. For my little project, I need to take a line (say, all pixels along a diagonal line) from an image and copy it to another image, one pixel high. As if taken with a line scan camera. The most obvious way would seem to use a quad and render it to that one-pixel-high image, but apparently that's no...
