Screen Block Grabber

Screen Block Grabber is a snipping tool that also packs a bunch of extra goodies to enhance the whole screenshot taking process.
As compared to other similar apps, Screen Block Grabber comes with a resizable window that needs to be moved around the screen in order to capture the covered area.
On the other hand, once a new snapshot is made, the photo is automatically loaded in the main window of the application where you can apply a series of filters and perform basic editing tasks.
There are several image effects at your disposal, including sepia, purple haze, negative, posterize, solarize, relief, emboss, gold and farmville.
What’s more, the Oil Painting Lab can assist you in applying even more interesting filters such as blur and edge detection. Subsequently, you can resize the pictures according to user-defined settings.
Screen Block Grabber benefits from hotkey support with the possibility to capture desktop activity in three different modes: the visible desktop of the primary monitor (Printscreen key), the active window (Alt+Printscreen) or the client area of the active window (Ctrl+Printscreen).
Another awesome feature is the support for stenographic encryption, which allows users to hide text inside a picture. The encoding and decoding of the text are performed based on public and respectively, private keys that can be acquired from the developer for a fee.
Last, but not least, the software provides the ability to upload the edited screenshots to a dedicated online service such as PhotoBucket, ImageShack, Flickr, etc, as well as to transfer the files to the cloud or to a FTP server.
All things considered, Screen Block Grabber is an interesting project that acts decently and carries out the job it was built for. It benefits from a wise selection of effects, hotkey support and a steganography feature for hiding messages into images.
