-------------------------------------
Summary: 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
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?
