VeryPDF Black Border Removal SDK (API) allows the automatic black border detection and removal in monochrome or gray-scale images. The black border is produced in the images acquired by scanners when paper size is smaller than scanning area or in images acquired from microfilm, microfiches and aperture-cards. Removing the border from the images is a very important pre-processing step that improves the compression rate, reducing file size, and the visualization aspect.

VeryPDF Black Border Removal SDK allows user to remove black borders from monochrome images, gray-scale images and in color images!

Questions:

I scanned some books and randomly there are pages with a black border because of skewing in different sides of the page (probably because the page was not cut straight).

What i would like to do is either:

1.Automatically Color the black borders in white
2.Automatically Cut the black borders

I've attached an example showing the problem that I have.
