fixColorModel
protected static java.awt.image.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 java.awt.image.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.
