Example 26 with ICC_ColorSpace

use of java.awt.color.ICC_ColorSpace in project acs-aem-commons by Adobe-Consulting-Services.

the class CMYKJPEGImageReader method createRGBAImageFromRGBA.

/**
 * Creates a buffered image from a raster in the RGBA color space, converting
 * the colors to RGB using the provided CMYK ICC_Profile.
 *
 * As seen from a comment made by 'phelps' at
 * http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4799903
 *
 * @param rgbaRaster A raster with (at least) 4 bands of samples.
 * @param rgbaProfile An ICC_Profile for conversion from the CMYK color space
 * to the RGB color space. If this parameter is null, a default profile is used.
 * @return a BufferedImage in the RGB color space.
