How to Dither DJVU Files Using C#

Efficiently optimizing images for web placement is crucial for ensuring a smooth user experience. One approach to such optimization involves reducing the image’s color palette, thereby decreasing its file size and improving page load times. However, to prevent the disruption of smooth color gradients and the emergence of sharp boundaries in monochromatic areas, it’s essential to employ the image-smoothing function, known as dithering. This technique allows you to introduce a controlled amount of "noise" to an image or photograph, which, in turn, has a positive effect by smoothing out transitions within the color field and enhancing the image’s overall visual appeal. In order to Dither DJVU files, we’ll use Aspose.Imaging for .NET API which is a feature-rich, powerful and easy to use image manipulation and conversion API for C# platform. Open NuGet package manager, search for Aspose.Imaging and install. You may also use the following command from the Package Manager Console.

  • About Aspose.Imaging for .NET API

    Aspose.Imaging API is an image processing solution to create, modify, draw or convert images (photos) within applications. It offers: cross-platform Image processing, including but not limited to conversions between various image formats (including uniform multi-page or multi-frame image processing), modifications such as drawing, working with graphic primitives, transformations (resize, crop, flip&rotate, binarization, grayscale, adjust), advanced image manipulation features (filtering, dithering, masking, deskewing), and memory optimization strategies. It’s a standalone library and does not depend on any software for image operations. One can easily add high-performance image conversion features with native APIs within projects. These are 100% private on-premise APIs and images are processed at your servers.

    DJVU What is DJVU File Format

    DjVu, pronounced as “déjà vu”, is a graphics file format intended for scanned documents and books especially those which contain the combination of text, drawings, images and photographs. It was developed by AT&T Labs. It uses multiple techniques like image layer separation of text and background images, progressive loading, arithmetic coding and lossy compression for bitonal images. Since DJVU file can contain compressed yet high-quality colour images, photographs, text, and drawings and can be saved in less space therefore, it's used on web as eBooks, manuals, newspapers, ancient documents, etc.
