Class FastCMYKToRGB

java.lang.Object

com.twelvemonkeys.imageio.plugins.jpeg.FastCMYKToRGB

All Implemented Interfaces:

RasterOp

class FastCMYKToRGB
extends Object
implements RasterOp

This class performs a pixel by pixel conversion of the source image, from CMYK to RGB.

The conversion is fast, but performed without any color space conversion.

public FastCMYKToRGB()

Method Details

filter

public WritableRaster filter(Raster src,
 WritableRaster dest)

Converts the CMYK source raster to the destination RGB raster.

Specified by:

filter in interface RasterOp

Parameters:

src - assumed to be 4 byte CMYK

dest - raster, in either 3 byte BGR/BGR, 4 byte ABGR or int RGB/ARGB format, or null

Returns:

dest, or a new WritableRaster if dest is null.

Throws:

IllegalArgumentException - if src and dest refer to the same object
