      extended by org.apache.batik.ext.awt.image.rendered.Any2LsRGBRed
All Implemented Interfaces:
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 WritableRaster copyData(WritableRaster wr)

fixColorModel

protected static 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 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.
