Ultimate C# .NET Imaging API Library Solution

.NET Server-Side Image Processing API

Comprehensive Feature Rich API for Image Processing

This flexible .NET imaging library allows developers to create, edit, and enhance images programmatically. It supports a wide range of image formats including JPEG, PNG, BMP, TIFF, GIF, ICO, SVG, and WebP. Developers can apply advanced image processing techniques such as cropping, resizing, rotating, blending, dithering, and thresholding. The API also enables drawing shapes and text, working with animated GIFs and multi-frame TIFFs, extracting and editing EXIF metadata, rendering HTML to images, and generating complex layouts with tables and styled graphics, all without relying on external image editing tools.

Complete Client-Server Image Processing Solution

A Document Solutions for Imaging .NET purchase includes a Standard license for the JavaScript Image Viewer (DsImageViewer), delivering powerful client-side image viewing and processing. Developers can load, view, and manipulate a wide range of image formats directly in the browser, while the built-in client-side API makes it easy to create, edit, and save images programmatically.

For extended capabilities, optional plug-ins allow you to add advanced features such as rotation, filters, and effects—keeping the viewer lightweight while giving you full control over functionality. DsImageViewer integrates seamlessly with major web frameworks, works across modern browsers, and provides a customizable interface for embedding image viewing and editing into any application.

.NET Imaging API Features

Apply Effects to Images Programmatically

Apply Effects

Apply advanced image effects like blur, grayscale, brightness, contrast, hue adjustments, and thresholding to transform or analyze images. Ideal for both stylized rendering and technical workflows such as document enhancement, medical imaging, or pre-print processing.

Reduce Image Size Programmatically or at Scale using C#

Resize Images

Dynamically resize images in your .NET applications while preserving quality. Scale up or down with precision for web, print, or display optimization.

Programmatically crop images using a .NET API

Crop Images

Programmatically crop images to specific dimensions or regions using C# in your .NET applications, perfect for focusing on key content or automating image cleanup.

Programmatically Rotate and Flip images using a .NET API

Rotate & Flip

Easily rotate or flip images in various orientations, including 90°, 180°, and mirrored layouts, using built-in image transformation methods. Perfect for re-orienting photos, scanned documents, or layout adjustments with high performance and minimal code.

Change Image Resolution using C# .NET

Change Resolution

Adjust the resolution (DPI) of images to meet print, screen, or format-specific requirements without changing pixel dimensions. Ideal for optimizing output quality, aligning with document standards, or preparing images for professional publishing and archiving.

Change Image Background

Change Image Background

Easily replace or modify the background of an image using the .NET API. Add transparency, solid colors, or custom designs programmatically.

Apply transparency masks to image files using .NET

Transparency Mask

Apply transparency masks to selectively hide or reveal parts of an image using grayscale or bilevel inputs for pixel-level control. Ideal for creating layered compositions, custom fades, or dynamic masking effects in image editing, UI design, or document rendering workflows.

Programmatically Work with Images Colors using C# or VB

Work with Image Colors

Enhance and analyze image colors with precise control over brightness, contrast, and color channels. DsImaging supports automated corrections, channel isolation, histogram adjustments, and color quantization, which is perfect for improving clarity, reducing color depth, or preparing optimized visuals for constrained environments.

Add Watermarks to Images Programmatically using C# or VB

Image Watermarks

Easily apply text or image watermarks to your graphics using the .NET API, which is ideal for branding, copyright protection, or document labeling.

Render Text to Images in .NET Apps

Render Text

Support advanced text layout engine with full font support, text processing, layout and formatting follows Unicode standards.

Add Shapes and graphics to Images using C#

Draw Shapes

Draw custom shapes and vector-style graphics directly on images using high-level drawing commands. Ideal for creating diagrams, annotations, or composite visuals by rendering lines, polygons, paths, and other geometric elements with precision.

Add Graphics to Images using C#
