Overview

A .NET Imaging API is a programming interface that allows developers to programmatically create and manipulate images at scale. Document Solutions for Imaging (DsImaging) is a solution allowing developers to load, process, and save images across many different formats in desktop and web-based applications.

Benefits of a C# .NET Imaging API

Fast and Efficient

Save memory with the small file size and time with the lightweight API architecture. Scalable, flexible, efficient, and fast to handle small and large TIFFs at top speed. Integrate with a JavaScript client-side Image Viewer to load, view, edit and save images.

Image Processor

Meet all the needs of a basic image processor: resize, convert, rotate, and flip images. Create, apply, and align the images in your apps that you need when you need them.

Advanced Image Effects

Convert average images into high-quality, detailed images in less time. Apply advanced image effects like dithering, thresholding effects, half-tone transparencies, resolution editing, grayscale conversion, effects on RGB images, and more.

Text and Graphics

Dynamically enhance your images with logos and text. With extensive font, layout, and graphic support, you can convert your images into branding elements and professional pages.

Full .NET Core Support

Develop for any .NET platform or major operating system like Windows, Linux, and Mac with a single code base. Use in your apps for .NET Core, .NET Framework, Mono, Xamarin.iOS, and Xamarin.Android.

Image Processing to the Cloud

Be everywhere with cloud-based deployment. With NuGet and DsImaging, you can deploy to Azure, AWS, and AWS Lambda to create services that manage and convert images on the cloud.

Programmatically Compare Images using C# or VB.NET

Image Comparison

Compare images for software testing, image manipulation detection, or comparing shots from security frames. Perform fuzzy image comparisons and generate different images. This tool provides an effective way of comparing a variety of image types.
