Miraplacid Screen Capture saves screenshots to JPEG, PDF, TIFF, PNG, BMP and TGA image files or redirects them to a printer. It overrides default Print Screen button behavior with preview panel. There you can scale the screenshot, adjust gamma and colors, crop borders and save the result as an image file. Alternatively, you can redirect the enhanced screenshot directly to a printer.
Like with regular Print Screen button, you can push Print Screen to make a screenshot of a whole screen or you can push Alt + Print Screen to make a screenshot of the active window.
