/** * Converts image raster data to a JPEG with RGB color space. Only images with color space CMYK and YCCK are * converted, other images are left untouched. * * Rationale: Java's ImageIO can't process 4-component images and Java2D can't apply AffineTransformOp either, * so we have to convert raster data to a JPG with RGB color space. * * The technique used in this method is due to Mark Stephens, and free for any use.
