upFilter Lanczos3 The filter kernel to use for upsampling:
• Gaussian
• Triangle
• Box
• Bell
• BSpline
• Sinc
• Lanczos2
• Lanczos3
• Lanczos5
• Mitchell - remapped pixels receive some
smoothing, plus blurring to hide pixelation.
• Bilinear - gives good results, but can produce
square artifacts at extreme zoom.
• Bicubic - provides more rounded results,
slightly blurrier but without the square
artifacts.
• Nearest - preserves edge detail, but gives
quite "blocky" textures.
highlightCompensation enabled When enabled, Katana adaptively compresses
pixel values prior to transform filtering and re-
expands them afterwards. This helps to reduce
the ringing in high-contrast areas that can be a
problem in linear floating point images (as we
have in Katana).
