All Implemented Interfaces:

java.awt.CompositeContext

Enclosing class:

SVGComposite

public static class SVGComposite.OverCompositeContext_INT_PACK_UNPRE

extends SVGComposite.AlphaPreCompositeContext_INT_PACK

This implements SRC_OVER for Int packed data where the src is unpremultiplied. This avoids having to multiply the alpha on the the source then divide it out again.

Method Summary

void	compose(java.awt.image.Raster src, java.awt.image.Raster dstIn, java.awt.image.WritableRaster dstOut)
void	precompose_INT_PACK(int width, int height, int[] srcPixels, int srcAdjust, int srcSp, int[] dstInPixels, int dstInAdjust, int dstInSp, int[] dstOutPixels, int dstOutAdjust, int dstOutSp)
