Without too much difficulty, I managed to convert my sRGB image into CMYK with my profile by using JNA to utilize Little CMS. I took the resulting samples, sanity-checked them, and then stuffed them into a WritableRaster with a PixelInterleavedSampleModel.
I figured that from here it would be a snap to save to a CMYK image file, perhaps in TIFF format, but I've been poring through Image I/O and I don't see how to do it. Can anyone help? -Adam
