Damjan Jovanovic resolved IMAGING-89.
-------------------------------------

       Resolution: Fixed
    Fix Version/s: 1.0

I've just committed a fix for this to the latest SVN. Imaging.getImageInfo() will now distinguish
the YCCK colorspace based on the App14 segment.

Resolving fixed.

> I use Sanselan/CommonsImaging to detect if uploaded images are in the RGB color space,
and if not convert them to RGB.
> Currently, CI marks jpg images in the YCCK color space as CMYK:
> ImageInfo info = Imaging.getImageInfo(is, "YCCK.jpg");
> info.getColorType() == ImageInfo.COLOR_TYPE_CMYK
> So I have to do a custom check afterwards to differ between YCCK and CMYK.
> I use the following to do this:
> import com.drew.imaging.jpeg.JpegSegmentReader;
> JpegSegmentReader reader = new JpegSegmentReader(is);
> byte[] appe = reader.readSegment(JpegSegmentReader.SEGMENT_APPE);
> bool isYCCK = appe != null && appe[11] == 2;
> Would it be possible to incorporate this into CommonsImaging?
