Image Markup Tools

Want to give users the ability to annotate images with lines, shapes, highlights, and text? This project provides flexible drawing tools and customization options for a variety of use-cases.

The above example shows a base image that has been marked up with a text box, polygon (that also happens to be "selected"), line with arrowhead endpoint, and a highlighted date/time.

NOTES

• Requires Olaf Schmidt's RC6 library available at https://www.vbrichclient.com/ - so make sure to have it installed and registered on your dev machine.
• This is a first-pass and the project has only been lightly tested so far. There are likely to be bugs, so please report any issues you discover and I will try to fix them ASAP.

Enjoy! :)
