created with the purpose of decoding either RGB or Y'CbCr samples.
For instance:
WebPIDecoder* idec = WebPINew(MODE_BGR);
WebPDecBuffer buffer;
WebPInitDecBuffer(&buffer);
buffer.colorspace = MODE_BGR;
...
WebPIDecoder* idec = WebPINewDecoder(&buffer);
As data is made progressively available, this incremental-decoder object
can be used to decode the picture further. There are two (mutually exclusive)
