I was cleaning out old source codes and found this old project, so I quickly created 3 new projects and updated it. I noticed there was an error with the last Linepaint app, so I fixed the border bug and added a border outline. Also, I quickly added a pixel editor and a threshold tool. The threshold tool is the same thresholding characteristic as is used by gimp. This is just a standard unit of measure, where you have 2 ranges instead of 1. So for example Adobe Photoshop's basic threhsold setting is for a single range. Gimp has a more versatile setup as a default in this way. I am attaching 3 projects, no binary files, I quickly slapped them together in visual studio community 2017. Please don't ask me questions about this. I'm not programming anymore and I just wanted to make sure, I leave behind some simple projects that were difficult for me when I was getting started. I hope you can make good use of them. Every once in a while if I find old sources and stuff I threw away, I will refresh them and try to drop them in the codebank.
