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

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.
