Sometimes I like to get a screen grab of a web page or application so that I can edit it for UI design purposes. Is there a way of getting a screen grab of the entire page (including ares which you'd have to scroll down in order to see) so I don't have to do two or more screen grabs and stitch them together?
For web pages there is a great add on called Screengrab! that allows you to capture an entire portion of a web page. I use it all the time for this kind of thing.
Try http://aviary.com/launch/talon. You'll have to set it at high quality if you're doing any kind of graphics work. If you have to log in somewhere or you're accessing something on an intranet, it probably won't work.
Here's another one that installs locally: Fireshot. It works for Firefox and IE. Here's a sample screenshot of SuperUser, click for hi-res:
The free version of FastStone Capture will do this.
See answer to this question - What’s the best Free alternative to SnagIt (Screenshot capture program)?.
This question is a duplicate of both:
Snipping Tool for Vista and Windows 7
Snagit (not free!)
