Hello , i have some problem in using Apache Common Imaging , please do me a
favor.
I want to write some text in a cmyk image in JPEG or TIFF. First , i got
BufferedImage from the source cmyk image in JPEG, and i found it is in RGB
color space , so I use ColorTools to convert it to cmyk color space, and save
it in JPEG and TIFF, but when i open the image file with photoshop , it's also
in RGB. The code does not work, or something i did wrong?
My code like this:
ICC_Profile rgbProfile = ICC_Profile.getInstance("D:\\test\\AdobeRGB1998.icc");
ColorSpace rgbColorSpace = new ICC_ColorSpace(rgbProfile);
ICC_Profile cmykProfile =
ICC_Profile.getInstance("D:\\test\\JapanColor2001Coated.icc");
ColorSpace cmykColorSpace = new ICC_ColorSpace(cmykProfile);
ColorTools colorTools = new ColorTools();
//BufferedImage cmykImage = colorTools.convertBetweenColorSpaces(image,
rgbColorSpace, cmykColorSpace);
BufferedImage cmykImage = colorTools.convertToColorSpace(image, cmykColorSpace);
ImageFormat format = ImageFormat.IMAGE_FORMAT_TIFF;
Map<String,Object> params = new HashMap<String,Object>();
params.put(ImagingConstants.PARAM_KEY_FORMAT, ImageFormat.IMAGE_FORMAT_TIFF);
Imaging.writeImage(cmykImage, new File("d:/test/yyyyyyyyy.tif"),
ImageFormat.IMAGE_FORMAT_TIFF, params);
I find some classes about cmyk in api doc , but i do not know how to use
them. And cannot found more information or document about it in internet.
so ... please give me some demo or point out my code error . Thank you!
