Hi,
Sorry, I was away for too long.

Thank you for the issue link.

@snibgo: Should I raise a new request for change of output format to "image property "%[EXIF:orientation]" not found." or will this(current) post suffice? This is not a problem faced just by me, but all(2 as of now) of my colleagues. So, I can say it's not just my personal view. ...

@snibgo, @fmw42: That was really unprofessional of me. My apologies for not only not providing proper information but also raising a incorrect question. Both these commands do work in both OSX and Mac. identify -format '%[orientation]' photo.jpg identify -format '%[EXIF:orientation]' photo.jpg The i...

There is an inconsistency while using IM between Ubuntu and OSX. The below command works on Ubuntu: identify -format '%[EXIF:Orientation]' <inputfile> However, on OSX(installed using brew), we have to use: identify -format "%[orientation]" <inputfile> This creates problem in writing platfo...

@fmw2: You can ignore cwebp/dwebp. The root problem is I am unable to read CMYK jpeg images using djpeg. As you said "JPEG supports CMYK and libjpeg will read or write it. IM uses libjpeg for JPEG files." I tried using 'djpeg', from `sudo apt-get install libjpeg-progs`. I tried both comman...

Thank you.
The question was about if djpeg cannot decode jpegs with CMYK profile, then how was imagemagick able to do it. The need arise because I was assuming that IM uses delegates for decoding an image, thus all decoding must be done by libjpeg, libpng, etc depending on the file type.

Hi,
This question comes as a follow up from no support of CMYK jpegs by cwebp.

Please check this: https://bugs.chromium.org/p/webp/issues ... ?id=311#c5

Since, CMYK is not supported by djpeg, how can imagemagick handle CMYK images. These images have color transform YCCK.
