Constructor Detail

Any2LumRed

public Any2LumRed(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 one or two bands based on if the source had an alpha channel.

getColorConvertOpAplhaSupported

protected static boolean getColorConvertOpAplhaSupported()

getAlpha

protected static int getAlpha(BufferedImage bufferedImage)
