C# DICOM - How to Annotate DICOM File

C#.NET DICOM Annotation Overview

In order to adding mature text and graphics annotating functions into C#.NET DICOM document imaging application, you may need three professional .NET document imaging libraries, which are RasterEdge.Imaging.Basic.dll, RasterEdge.Imaging.Annotation.dll and RasterEdge.Imaging.DICOM.dll. These DLL libraries enable C# developers to add more than ten annotation shapes on DICOM image file. In addition, saving annotated DICOM document to TIFF or PDF file is also supportive.

After integrating above three .NET DLLs into your C#.NET project, you are able to draw and add these annotation objects on DICOM document: rectangle, ellipse, line, lines, freehand, freehand lines, text, rectangular hotspot, freehand hotspot, embedded image, referenced image, polygon, rubber stamp, and call out annotations. Here, we provide an online document annotation demo, please click to have a try.

C#.NET DICOM Document Imaging - Annotating Features:

Fully written in managed C#, complying with VS 2005+ and .NET Framework 2.0+

Draw and add an arbitrary number of annotation objects on DICOM image file in C#.NET

Support annotation object oriented design for every DICOM document annotation

Capable of setting annotation properties when creating an annotation object on DICOM

Annotation objects created on DICOM can be moved, resized, rotated independently in C#.NET

Support burning text and graphics annotations onto DICOM image file with a single C#.NET method

Able to save and convert the DICOM document with annotation to TIFF and PDF using C# code

C#.NET DICOM Document Imaging - Annotating Demo

Here is a C#.NET demo code for creating and adding annotation on DICOM image file. Please firstly add the indispensable DICOM document imaging DLLs into your C#.NET project and copy the following demo code to have a test.

            DCMPage page = (DCMPage)dcmDoc.GetPage(0);
            // create a line annotation starting at point (0.0) and ending with point(50,50). Note, only relative position of the start and end points is used
            LineAnnotation line = CreateLineAnnotation(new LinePoint(10.0f, 10.0f), new LinePoint(50.0f, 50.0f));
            //add the line annotation on the page 
            page.AddAnnotation(line);
            dcmDoc.Save(@"F:\output.dcm");
