Introduce a rewritten picojpeg that is able to operate statefully and rasterize into an internal line ringbuffer, emitting a line of pixels at a time to the caller. This is the JPEG equivalent of the lws PNG decoder. JPEG is based around 8- or 16- line height MCU blocks, depending on the chroma coding, mandating a corresponding internal line buffer requirement. Example total heap requirement for various kinds of 600px width jpeg decoding: Grayscale: 6.5KB RGB 4:4:4: 16.4KB RGB 4:2:2v: 16.4KB RGB 4:4:2h: 31KB RGB 4:4:0: 31KB No other allocations occur during decode. Stateful stream parsing means decode can be paused for lack of input at any time and resumed seamlessly when more input becomes available. |
