/** * Scale an image using a high-quality filter. * * Synchronously scales an image and writes the output to the destination in * 32-bit format. The destination must be pre-allocated by the caller. * * Returns true if scaling was successful, and false otherwise. Currently, this * function is implemented using Skia. If Skia is not enabled when building, * calling this function will always return false. * * IMPLEMTATION NOTES: * This API is not currently easily hardware acceleratable. A better API might * take a SourceSurface and return a SourceSurface; the Direct2D backend, for * example, could simply set a status bit on a copy of the image, and use * Direct2D's high-quality scaler at draw time.
