I'm looking for a piece of desktop software, ideally free, that will help me to interactively convert some old hand-drawn jpg diagrams to svg.
It should recognize simple geometric forms like straight lines, triangles, rectangles, and curves such as circles and ellipses. It's probably too much to expect it to do OCR on handwriting, but it should have a way of adding annotations in various fonts and sizes.
The interface perhaps would show the original hand-drawn jpg in some kind of background pane, with the suggested and modifiable svg as an overlay.
Any language is fine, and something that is in progress or has been abandoned might also be useful.
Thanks in advance for any links or pointers or advice.
