Constructor Details

MultiplicativeCompositeContext

protected MultiplicativeCompositeContext(ColorModel srcColorModel, ColorModel dstColorModel, float preAlpha)

Method Details

composePixel

protected int composePixel(int srcARGB, int dstARGB)

Mixes two pixels together.

Parameters:

srcARGB - the incoming ARGB 32-bit integer value.

dstARGB - the existing, "source" ARGB 32-bit integer value.

Returns:

the resultant ARGB value.

checkRaster

protected static void checkRaster(ColorModel colorModel, Raster raster)

Checks if a Raster is the correct data format for this compositing operation.

Parameters:

colorModel - the color model to check compatibility for.

raster - the Raster to check.

Throws:

UnsupportedOperationException - if the Raster's data type is not DataBuffer.TYPE_INT.
