|

// (1) RemoveFrameRectFilter reads a 100x50 region of the input.
|
|
// (aInputWriteRect captures this fact.) The remaining 50 rows are ignored

|
// because they extend off the bottom of the image due to the frame rect's
|
|
// (50, 50) offset. The 50 columns on the right also don't end up in the
|
|
// output, so ultimately only a 50x50 region in the output contains data
|
|
// from the input. The filter's output is not 50x50, though, but 100x100,
|
|
// because what RemoveFrameRectFilter does is introduce blank rows or
|
|
// columns as necessary to transform an image that needs a frame rect into
|
|
// an image that doesn't.
|
|
//
|
|
// (2) DownscalingFilter reads the output of RemoveFrameRectFilter (100x100)
|
|
// and downscales it to 20x20.
|
|
//
|
|
// (3) The surface owned by SurfaceSink logically has only a 10x10 region
|
|
// region in it that's non-blank; this is the downscaled version of the
|
|
// 50x50 region discussed in (1). (aOutputWriteRect captures this fact.)
|
|
// Some fuzz, as usual, is necessary when dealing with Lanczos downscaling.
