As part of the development process of RequestSpot, our help desk software for multiple departments, we’ve created a tool that lets users capture a region, a window or the full screen of their computers and edit the image as needed. With the edit options, you can:

After editing you can save the image in JPEG format or copy it to the clipboard for further processing, send it to an email or paste it on a document.
The best part is that we’ve made the tool, the screen capture software, available for free so the community can take advantage of it. If you want any more features, just contact me and I’ll try to include it in the development schedule.
