Today PDFBox rendering uses the sRGB colorspace. I would like to render to CMYK colorspace using a ICC profile of my choice, without losing any color information. My choice today is to first render to sRGB than use ColorConvertOp to convert the resulting image from sRGB to the CMYK colorspace using my ICC profile. The problem is that this double conversion distorts colors. The perfect way to solve this is to add the possibility to select the desired output colorspace of my choice when calling PDFRenderer.renderPageToGraphics(). Another perhaps simpler way is to add the possibility to render to CieXYZ colorspace instead of sRGB colorspace. And then use ColorConvertOP from CieXYZ to CMYK.
Another request is the possibility to select the input CMYK colorspace. Today a standard ICC profile is hardcoded (see PDDeviceCMYK.getICCProfile(). I would like to specify the input color space as well. Stefan Karlsson
