When I quite unexpectedly started using the command line some years back, after discovering xnview.com's useful NConvert image processing utility, I had a quick look at ImageMagick, and am aware of Fred's ImageMagick scripts. However, coming from only a brief acquaintance with NConvert I found basic operations very different, and didn't continue when I could do what I needed more conveniently using NConvert. However, there is no doubt that ImageMagick supports many more specialist actions, and I believe there is an active community with some expert help available when needed.db-inf wrote: ↑18 Oct 2022, 03:16 You really do not need to be an image processing professional to get good images. ImageMagick is said to be well documented, but the tool is so powerfull that reading that documentation is unsurmountable. But there is a very usefull website with ready-made scripts, Fred's ImageMagick Scripts, from which I have let the textcleaner script loose on your two example images, with just the defaults, i.e. no options. Look for yourself.
I downloaded the textcleaner script to have a quick look and the download was a Linux script, possibly because I am mainly in Linux these days, although I suspect that there is also a Windows command line version. The script certainly includes many optional adjustments to optimise enhancement of a source image, and the example enhancements shown are impressive. But to obtain those results presumably it is necessary to run the script after each change and check the result, which makes me think that a tool with a GUI preview where the effect of changes can be seen immediately would, other things being equal, enable faster progress?
Here is a link to the textcleaner detailed description, scroll down through the scripts index to the description.
