Hi Everyone, I saw a very old posting posting from you on the JAVA2D interest group about color conversion and
Rendering intent quote: "When JAI detects ColorSpaces based on ICC profiles, it uses the Java2D ColorConvertOp class (java.awt.image.ColorConvertOp) to do color conversions. This class invokes native methods in the color management engine. ColorConvertOp currently supports only Perceptual intent. The only way in the Java2D API to get Relative Colorimetric intent is to call the toCIEXYZ/fromCIEXYZ methods on ColorSpace, which requires a lot of per pixel overhead. We would be interested to hear any requirements you have concerning rendering intents." Here is my angle: Absolute Colorimetric is a must in any color management framework and software for soft-proofing printed output on the screen. Example: Let's say I have an Image that is ready to print on press, CMYK composite tiff file and I want to soft-proof it on the screen. I have to open the Image and then convert it from the press profile to the screen profile. However If I want to simulate the color of the paper that will be printed (In Newspapers for example it could be "grayish" or "yellowish") I have to use the Absolute Colorimetric (Any other conversion "moves" the white point and won't create this affect). The absence of Absolute Colorimetric prevents me from using Java to do color conversions for soft proofing at all at this time (Have to use another language) Has anything changed since this old posting, any plans for future changes in Java2D or JAI ???
