I'm content enough with the three programs I was developing to officially release them, or at least as official as uploading them to the releases section of their github repository. The link to get the programs is here. They are compiled already, and they run in my office computer, so those programs probably run in most Windows systems. No idea if they run on Linux, but I guess you can clone the repository and compile it yourself.
I intended to make a video slideshow with many enlarged images generated with the programs, but turns out that YouTube has turned off that feature. So here are some far fewer images uploaded to a free image hosting site.
