History

James Jackson-South 0b685ab034 Fix convolution sampling for bounds smaller than the kernel radius KernelSamplingMap.CorrectBorder sliced the offset span by radius * kernelSize, so bounds narrower than the kernel radius threw ArgumentOutOfRangeException (GaussianBlur of a 130x8 region with sigma 10, for example), and bounds exactly equal to the radius let Bounce offsets escape the sampling range by folding an overshoot of a full extent to min - 1. Route bounds no larger than the radius through an exact per-mode correction that folds each offset into range: clamp for Repeat, periodic reflection for Mirror and Bounce, and true modulo for Wrap. The single-pass corrections are unchanged for larger bounds.		1 week ago
