      extended by org.apache.batik.ext.awt.image.rendered.Any2sRGBRed
All Implemented Interfaces:
RenderedImage, CachableRed

public class Any2sRGBRed
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.

Construct a luminance image from src.

src - The image to convert to a luminance image
Method Detail


public static boolean is_INT_PACK_COMP(SampleModel sm)


public static WritableRaster applyLut_INT(WritableRaster wr,
                                          int[] lut)


public WritableRaster copyData(WritableRaster wr)


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.


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.
