A recent thread Pull out image height requested a way to copy a specified image file parameter to a variable, which could then be used in a script. That could have general application, but would require familiarity with a scripting language.
Another possible solution might be to add a new NConvert option to convert an image only if a specified file parameter condition is satisfied; as access to file parameters is already available, that might not be difficult to implement.
Initial support might be for: height | width | filesize set to | greater than | less than .
So maybe something like:
Code: Select all
-convert height_px greater_than 720
