Class DecodeRasterOp

java.lang.Object

org.icepdf.core.pobjects.graphics.RasterOps.DecodeRasterOp

All Implemented Interfaces:

java.awt.image.RasterOp

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

Applies the decode value array tot he specified raster. The decode array is specific to PDF and describes how to map image samples into the range of values appropriate for the image’s colour space.

This Raster Operation should be applied to any image type before colour conversion takes place.

Since:

5.1
