[Sorry if this gets posted twice; I managed to send the first one with the wrong From: address]. Hi. I've looked through the docs and (briefly) the list archives, but I can't figure out if it's possible to efficiently process the input to a GeglOperation in a scanline fashion -- i.e. with access to, and outputting, only the pixels of a single, complete row at a time. I'm trying to write a Floyd-Steinberg dithering implementation, and the way the algorithm is specified, the order in which pixels are processed is significant. It "pushes" the quantization error ahead of it to the next pixel and to pixels on the next scanline. For more background see [1]. Is there an efficient way of doing this in a GEGL op?
