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

```
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.
