This was a bug of my own committing. In short, the original Expr logic didn't work as first intended. We're replacing a bitwise-and, and the original addition approach simply didn't work. Here's an example: For two pixels in the binarized mask clips (using 8-bit values for reference, but all bitdepths scale appropriately): Expected: x | y | result -------------- 0 | 0 | 0 0 | 255 | 0 255 | 0 | 0 255 | 255 | 255 Actual (old code for 11+ bit depth) Expr = "x y +" x | y | result -------------- 0 | 0 | 0 0 | 255 | 255 255 | 0 | 255 255 | 255 | 255 (because Expr clamps to bit depth peak) Actual (new code for 11+ bit depth) Expr = "x y + (255 + 1) < 0 255 ?" (examples in 8 bit depth, but scales to higher) Aka - if the sum of two pixels is less than the peak + 1 (aka <= the peak), then output 0, else output the peak. I'm simplying using "peak + 1" here to save some cycles, taking the "<=" down to just a "<" x | y | result -------------- 0 | 0 | 0 0 | 255 | 0 255 | 0 | 0 255 | 255 | 255 (because Expr clamps to bit depth peak)
