That's a great shot... Greenshot
Screenshots. We all do them. Windows 7's Snipping Tool is okay, yet pretty minimal, but the price isn't bad. There's the granddaddy utility, SnagIt from TechSmith, which has more bells and whistles than you can shake a stick at, but is not free. Then there's the many screen capture features with Microsoft Office, Expression Encoder, etc, etc. But none of these are open source...
Greenshot, the free, open source (C#), screenshot utility, with plug-in support too.
What is Greenshot?
Greenshot is a light-weight screenshot software tool for Windows with the following key features:
Create complete or partial screenshots quickly. Easily annotate, highlight or obfuscate parts of the screenshot. Send the screenshot to a file, the clipboard, a printer or as e-mail attachment.
Being easy to understand and configurable, Greenshot is an efficient tool for project managers, software developers, technical writers, testers and anyone else creating screenshots.
Greenshot is free and open source
Greenshot was published under GPL, i.e. this software can be downloaded and used free of charge, even in a commercial environment.
When they say "screenshot tool optimized for productivity" you can see if in features like the obfuscate tool.
Let's look at the Solution;
When/if you download the code you'll need to do a few minor things to get it to compile. Each Project has a pre-build event setup that you'll need to remove, you'll need to rename the assemblyinfo.cs.template (removing the ".template" and then updating the version number in that file. Once you've done that, the project should compile (at least it did on my machine...
Here's a snap of it running on my machine, via the downloaded source (post above fix-up)
One of the nice touches is the number of languages it supports;
If you're looking for a free screenshot tool, one with plug-in support, a cool project to help out on, one that's under very active development (the last check-in was four hours ago, from the writing of this post) or just some interesting source to read, this is a project that you might want to check out.
