If I export an image with lets say 300 DPI and I read out its meta-info with any application that can do it (like
mediainfo etc.), I always get a value showing Image-Width and Image-Height.
In this case:
2254 x 288
how do I get the 300 DPI value, or the corresponding value from any other image file?
Since in my case the proportional value of Image-Width and Image-Height does not matter I want to be able to check the resolution of any image to be able to compile new images with the same quality independent of their proportion, since this varies on every file.
For my workflow I'm especially interested in any command line solution, though any others are of course highly appreciated too.
