Screen Hunter is more than a Screencaptor, because it allows you to edit the captured image. You will be able to add text or highlight some parts of the image by adding colored lines, circles, several shapes, or simply draw something on it.
If you have to capture an screen and highlight something, this is your program because you will no need a third party program to edit the captured image.
You can choose how you will capture the screen, as a jpg, bmp or pcx file. And you will choose the area that ScreenHunter will capture.
