My goal is to determine the compression parameters of the jpeg image that I have. As I understood from this answer, it's possible using the ImageMagick function identity. I downloaded from the official site and installed ImageMagick-7.0.2-7-Q16-x64-dll.exe. Now, I have an application with GUI called ImageMagick Display that seems useless. Where can I find an IM command line to type this:
identify -format '%Q' yourimage.jpg
Since it is version 7.x, there is a checkbox at the time of installation that says 'Install legacy utilities (e.g. convert)'. You need to select that checkbox during installation.
Once done, you will be able to use the commands from command line.
Another option is to use the command magick identify --version
For version 6.x, it is not necessary.
