MkSIS is a new Singe-Image-Stereogram application for Windows 10. It consists of a command-line "backend" and GUI "frontend". Everything needed for running MkSIS is included in a single directory--additional software is unnecessary.
Being self-contained makes installation very simple. Just unZip the archive, copy the shortcut to the desktop and it's good to go!
The "backend" is a console program written in C. It has many capabilities and can be used as a standalone SIS generator. It is designed to produce high-quality stereograms with very few artifacts, in fact output is generally artifact-free.
The GUI "frontend" is a TclTk application that makes it easy to supply the numerous command-line options to the sis-backend. What's unique is having everything needed to run the GUI is included in the directory which means it's NOT necessary for users to have tcltk installed on their systems.
This is accomplished by a special "runner" utility which provides the appropriate environment and invocation for the included wish binary, so nothing else is needed.
It's all open source. Developers can easily adapt elements of the project for their own purposes. The single-directory TclTk facility could be an alternative to tclkits, freewrap and the like. In whatever way it would be useful, porting MkSIS components to other OS should be straightforward.
