## org.apache.xmlgraphics.image.rendered
Class Any2LsRGBRed

    java.lang.Object
      org.apache.xmlgraphics.image.rendered.AbstractRed
          org.apache.xmlgraphics.image.rendered.Any2LsRGBRed

All Implemented Interfaces:
  java.awt.image.RenderedImage, CachableRed

    public class Any2LsRGBRed

extends AbstractRed

This function will tranform an image from any colorspace into a luminance image. The alpha channel if any will be copied to the new image.

Constructor Detail

### Any2LsRGBRed

    public Any2LsRGBRed(CachableRed src)

  Construct a luminace image from src.

  Parameters:
    `src` - The image to convert to a luminance image

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.
