  • Big API reorganisation. Now libpipi can transparently convert between colour spaces for a given image. For instance, if pipi_gaussian_blur is applied to a 32-bpp image, it is automatically converted to gamma-corrected 32-bit floats beforehands, then converted back to normal.
  • TODO: clipping, regions of interest, more formats, getpixel macros...
