Web29 de jan. de 2011 · Suppose you have a point (0,0) and after the transformation it becomes (0.23,5.6), then you are not directly writing to a pixel in the output image, but a floating point 2d position between pixels. In this case, you could do an “anti-aliasing” kind of method, where you write the weighted average to a neighborhood of, say, 9 pixels. flowers for front porch pots
