Method Detail

coerceColorModel

public static java.awt.image.ColorModel coerceColorModel(java.awt.image.ColorModel cm,
                                         boolean newAlphaPreMult)

Create a new ColorModel with it's alpha premultiplied state matching newAlphaPreMult.

Parameters:

cm - The ColorModel to change the alpha premult state of.

newAlphaPreMult - The new state of alpha premult.

Returns:

A new colorModel that has isAlphaPremultiplied() equal to newAlphaPreMult.

coerceData

public static java.awt.image.ColorModel coerceData(java.awt.image.WritableRaster wr,
                                   java.awt.image.ColorModel cm,
                                   boolean newAlphaPreMult)

Coerces data within a bufferedImage to match newAlphaPreMult, Note that this can not change the colormodel of bi so you

Parameters:

wr - The raster to change the state of.

cm - The colormodel currently associated with data in wr.

newAlphaPreMult - The desired state of alpha Premult for raster.

Returns:

A new colormodel that matches newAlphaPreMult.
