Arthur Bogaart updated IMAGING-89:
----------------------------------
Attachment: test-YCCK.jpg
Attached YCCK test image
> Detect the YCCK color space/type
> --------------------------------
>
> Key: IMAGING-89
> URL: https://issues.apache.org/jira/browse/IMAGING-89
> Project: Commons Imaging
> Issue Type: New Feature
> Components: Format: JPEG
> Affects Versions: 1.x
> Reporter: Arthur Bogaart
> Priority: Minor
> Attachments: test-YCCK.jpg
>
>
> 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?
