Motivation: it would be a good idea if the API documentation examples were checked into the skia repository, so we could make sure they compile as part of the commit queue. Fiddle would make/update a named fiddle each time it gets a new commit of Skia, extracted from the code in the examples/ directory. The docs would point at those named fiddles. Named fiddles have urls in the form: https://fiddle.skia.org/c/@Bitmap_000 Then we would stick a link to the example into the header documentation like this: /** Allocates the pixel memory for the bitmap, given its dimensions and SkColorType. Returns true on success, where success means either setPixels() or setPixelRef() was called. @param bitmap SkBitmap containing SkImageInfo as input, and SkPixelRef as output @return true if SkPixelRef was allocated @example https://fiddle.skia.org/c/@Bitmap_000 */ bool allocPixelRef(SkBitmap* bitmap) override; There are still around 200 disabled examples that need to be fixed (these result from API changes since the author left).
