Expand description
Returns the RGB/A image decoded so far. Returns NULL if output params are not initialized yet. The RGB/A output type corresponds to the colorspace specified during call to WebPINewDecoder() or WebPINewRGB(). *last_y is the index of last decoded row in raster scan order. Some pointers (*last_y, *width etc.) can be NULL if corresponding information is not needed. The values in these pointers are only valid on successful (non-NULL) return.
