Convert images DJVU to ICO via C#
Transform images DJVU into ICO using native .NET APIs without needing any image editor or 3rd-party libraries
Aspose.Imaging for .NET
Overview
How to Convert DJVU to ICO Using C#
Converting file formats may seem like a routine task encountered by graphic designers. Yet, underestimating its significance would be a mistake. The evaluation of your work might depend on how swiftly and effectively you tackle this task. Typically, original images need conversion into formats better suited for printing or online publication. If the original image originates from a graphic editor, it might be in vector format. In this scenario, it must be rasterized and converted to a raster format for publishing purposes. You have the choice to save the image in an uncompressed format for optimal quality or convert it to a lossless compressed format to reduce file size. In certain contexts, like web publishing, you can opt for lossy compressed formats. Specially designed algorithms for image data compression permit a significant reduction in file size while preserving acceptable image quality. This facilitates fast image file downloads from the internet. In order to convert DJVU to ICO, 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.

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.

The ICO file format is an image file format for computer icons in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths, such that they may be scaled appropriately. In Windows, all executables that display an icon to the user, on the desktop, in the Start Menu, or in Windows Explorer, must carry the icon in ICO format.
