# Image cleanup demo

This sample application demonstrates DocuVieware as an application designed to clean up documents that have been acquired.

It comes with a preloaded document that contains various processing candidates that will conveniently enable you to test the cleanup features available in the demo.

[Try demo](https://www.docuvieware-demo.com/image_cleanup.aspx)

Operations that you’ll be able to use are black border cropping, deskew, punch hole removal, negative, despeckle, and 90-degree rotation in both directions.

> The black border cropping internally calls the `DeleteBlackBorders` method from the `GdPictureImaging` class, which requires a 1-bit-per-pixel image. Therefore, this method can’t be applied to the last page, which is a grayscale image.
