7capture is a free tool which allows users to take screenshots of any window removing the background image and retaining semi-transparency.
7capture screenshot tool for Windows
No matter what Windows version you are using, 7capture will do its magic: clean rounded corners on Windows XP, alpha transparency in Windows Vista and Windows 7 / 8.
7capture will even capture your theme’s color for even better looking screenshots.
7capture automatically handles complicated transparency problems such as rounded corners and Aero semi-transparent windows backgrounds.
You can export your capture as semi-transparent png, jpeg, gif or bmp formats.
Visit its Home Page for downloading it.
I have tried to download this but every time I run the installer I get the message. “The setup files are corrupted. Please obtain a new copy of the program.”
Strange. I just tried it again and I could. Maybe you could clear cache and try again – perhaps with a different browser too…
Thanks, it worked with IE 8 but not Firefox.
