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. It will also help ...

@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 ...

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 platform ...

@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 commands below ...

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.
