      • sRGBToLsRGBLut

        private static final int[] sRGBToLsRGBLut
        Lookup tables for RGB lookups. The linearToSRGBLut is used when noise values are considered to be on a linearScale. The linearToLinear table is used when the values are considered to be on the sRGB scale to begin with.

      • Any2LsRGBRed

        public Any2LsRGBRed​(CachableRed src)
        Construct a luminace image from src.
        Parameters:

    • Method Detail

      • sRGBToLsRGB

        public static final double sRGBToLsRGB​(double value)
      • copyData

        public java.awt.image.WritableRaster copyData​(java.awt.image.WritableRaster wr)
      • fixColorModel

        protected static java.awt.image.ColorModel fixColorModel​(CachableRed src)
        This function 'fixes' the source's color model. Right now it just selects if it should have one or two bands based on if the source had an alpha channel.
      • fixSampleModel

        protected static java.awt.image.SampleModel fixSampleModel​(CachableRed src)
        This function 'fixes' the source's sample model. Right now it just selects if it should have 3 or 4 bands based on if the source had an alpha channel.
