C# Image SDK Programming - Getting Started
Here we provide links to four major C# imaging functions (image processing, image annotation, image conversion and image drawing), which will guide you how to program C# codes for document image file processing, annotation, conversion, and drawing using this C#.NET Imaging SDK.
C# Image Processing C# Image Converting
RasterEdge Visual C# .NET processor toolkit supports multiple image processing functions, including C#.NET image resizing, image cropping, image rotating, image scaling, image flipping, thumbnail creating and watermark drawing. Fllow this link and you will find detailed online guidance on C#.NET imaging conversion between image and byte array, between image and stream, between Word and image, between PDF document and image file, etc.
C# Image Annotation C# Image Drawing
This C#.NET imaging annotation SDK supports most commonly-used annotating methods for C#.NET class applications, like callout, ellipse, freehand, hotspot, line, polygon, rectangle, rubberstamp and text annotations. This C#.NET image drawing add-on from RasterEdge .NET image programming SDK is used to help C# developers draw text and graphics on document image file in .NET developing platforms, like web-based application and WinForms project.
C#.NET Image Programming SDK FAQs
Q: I downloaded C#.NET image programming SDK but it did not work in my C#.NET class application.
A: There are often two reasons that cause the failure of RasterEdge image programming SDK. One is that your C#.NET developing environment does not meet the installation requirements of RasterEdge image programming SDK (Visual Studio 2005 or above and .NET Framework 2.0 or greater).
The other is the evaluation license key issue. Before you use any programming add-ons from RasterEdge DocImage SDK for .NET, please make sure that you have activated the evaluation license key (which can only be activated twice within one computer and each evaluation license key can be valid within 30 days) and that you have placed activated license key at the bin folder of your C#.NET project, usually together with integrated RasterEdge image programming dlls.
If your issue is beyond above mentioned situations, please feel free to contact our technical team at
