Thanks! I like that better too. So the API could be as follows: enum CanvasMaskType { luminosity, alpha}; dictionary maskOptions { CanvasImageSource image; unrestricted double? sx; unrestricted double? sy; unrestricted double? sw; unrestricted double? sh; unrestricted double dx; unrestricted double dy; unrestricted double? dw; unrestricted double? dh; CanvasMaskType? maskType = "luminosity"; boolean? invert = false; boolean? clipToMask = true; } void maskImage(maskOptions options); void resetMask(); If not specified, the dw and dh arguments must default to the values of sw and sh, interpreted such that one CSS pixel in the image is treated as one unit in thescratch bitmap's coordinate space. If the sx, sy, sw, and sh arguments are omitted, they must default to 0, 0, the image's intrinsic width in image pixels, and the image's intrinsic height in image pixels, respectively.
