Class CMYKRasterOp

java.lang.Object

org.icepdf.core.pobjects.graphics.RasterOps.CMYKRasterOp

All Implemented Interfaces:

java.awt.image.RasterOp

public class CMYKRasterOp
extends java.lang.Object
implements java.awt.image.RasterOp

Raster operation for converting a CMYK colour to RGB using an a rough algorithm which generally results in images that are darker then they should be. The black value can be configured using the system property -Dorg.icepdf.core.cmyk.image.black=255.

This colour conversion method should only be used if its not desirable to use the more accurate ICC Color Profile for colour conversion.

Since:

5.1
