Cropper screen capture

Cropper is a screen capture utility . It makes it fast and easy to grab parts of your screen. Use it to easily crop out sections of vector graphic files such as Fireworks without having to flatten the files or open in a new editor. Use it to easily capture parts of a web site, including text and images. It’s also great for writing documentation that needs images of your application or web site.

Screen capture Output

  • Cropper is able to output images to a variety of formats. There is an extensibility model allowing developers to create custom output plug-ins. Descriptions of some of the default plug-ins are given below.
  • BMP: Large files but no compression artifacts.
  • PNG: Smaller files with lossless compression, good for most image formats except full color photographic. Think of it as a replacement for the simpler GIF format. All modern browsers can display a png file.
  • JPEG: Good for full color photographic images. Cropper can save jpg’s in varying quality settings from 10 to 100. 10 being the lowest quality and smallest file size. 100 being the highest quality and largest file size. A quality setting of 60-70 is usually good for the web. It’s a good trade off between file size and image quality.
  • Clipboard: The image is placed on the clipboard and can be pasted into any application that accepts images.
  • Printer: Presents a print dialog that allows you to send the image straight to the printer.

Known Issues

The maximum size of the crop form is smaller than the screen size. This is a limitation of the way the UI is currently drawn. There is an area of transparent form around the visible area which causes Cropper to appear to be smaller than the maximum form size. With the original usage of cropping out small areas of the screen this was not pressing problem.
