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.

Constructor Details

Any2sRGBRed

public Any2sRGBRed(CachableRed src)

Construct a luminance image from src.

Parameters:

src - The image to convert to a luminance image

Method Details

is_INT_PACK_COMP

public static boolean is_INT_PACK_COMP(SampleModel sm)

applyLut_INT

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

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.
