The same options are provided as for the warp modules, but with the addition of lanczos3. pixel interpolator (scaling) The pixel interpolator used for scaling. In general, bicubic is a safe option for most cases and is the default value. For warping modules, darktable offers bilinear, bicubic or lanczos2. Whenever we scale or distort an image we have to choose a pixel interpolation algorithm (see wikipedia for details). pixel interpolator (warp) The pixel interpolator used for rotation, lens correction, liquify, crop and final scaling. ![]() If the given ICC is LUT-based or contains both a LUT and a matrix, darktable will use LittleCMS 2 to render the colors regardless of this parameter’s value (default off). This is significantly slower than the default but might give more accurate results in some cases. ![]() □image processing always use LittleCMS 2 to apply output color profile If this option is activated, darktable will use the LittleCMS 2 system library to apply the output color profile instead of its own internal routines.
