Images

This demo illustrates how you can open low quality images, and adjust either the gamma, brightness, color saturation or the contrast making them appear better and more pleasing to the naked eye.

Since binarization (thresholding) is a pillar of the document image processing, we decided to dedicate a separate demo for this feature. Here you can choose one of a verity of thresholding algorithms, from the simple one like Linear, as well as the most known dithering algorithms like Ordered-Dither, Stucki, Burke, and FloydStienberg. Finally, we also included some of the most complex like Otsu and Sauvola. You can choose the algorithm that best fits your needs.

In this sample you can select one of the three main color channels (Red, Green, Blue) as your chrome key, and you can remove it or part of it according to a threshold you choose.

This demo shows you how to perform basic and sophisticated image processing filters on your image, including clean up, color conversion, bit depth conversion, recognition and much more. The very detailed C# sample utilizes together GdViewer, ThumbnailViewer, and has an action history panel.

In this sample you can rotate your images using a scrollbar. You can either rotate normally, rotate with a color filling the generated background,
rotate with dimensions preservation, or rotate at the centre with dimensions preservation.
