JPEG image identified as RGB instead of CMYK

See original GitHub issue

After reading this SO answer i assume TM supports the detection of color space model fr JPEG images conform spec.

However, this image returns RGB using

int type = bufferedImage.getColorModel().getColorSpace();

However, ImageMagick 6.9.7-4 reports

identify -verbose Vitocell_100-W_00019.jpg | grep Colorspace
Colorspace: CMYK

So does exiftool 10.80:

exiftool Vitocell_100-W_00019.jpg | grep "Color Space Data"
Color Space Data                : CMYK

So maybe this is a bug?

Thanks, even more clear now!

Thank you very much for all this information. Before pushing a PR, I need to invest more time in this subject / API. Maybe my notes can be a starting point for a FAQ.

All clear now. And indeed, this works! BTW I use JDK11 and behavior is still as you described 😦

In this thread you gave me a lot of (excellent) info that I cannot find anywhere (besides the metadata / javax_imageio_1.0 stuff). Is this indeed not documented? Or do i miss something?
