Oh no! I was thinking of the dt_iop_clip_and_zoom_demosaic_{half,third}_*() functions in imageop_math.c. Those don't have OpenCL implementations, though? Certainly getting into revising OpenCL code would be a way more invasive effort. I also remember now that I wanted to look into whether taking advantage of box filters being separable would speed up the code. But that would involve allocating a bit of memory so might also be something about which to be conservative. > > Ulrich [...] ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to darktable-dev+unsubscr...@lists.darktable.org
