HotShots can capture your screen and further edit the screenshot. While suited for writing documentation and highlighting important aspects of a map image, this capture tool covers more than the basics.
It can capture multi-monitor images, the desired desktop area, or the opened window. You can choose in what format to save the images, starting with JPG and PNG and ending with BMP.
Scaling and other post-processing edits come useful when you add a drop shadow, borders, etc. Once you have done that, saving the images is done automatically. While working in the background on low system resources, it also launches itself at the start-up.
Several other parameters offer background colors, file name settings, and decoration capture.
