Jpeg2000Options Property

Summary

Gets or sets the JPEG 2000 compression options.

Syntax

C++/CLI

public DicomJpeg2000Options Jpeg2000Options { get; set; }

public: 
property DicomJpeg2000Options Jpeg2000Options { 
   DicomJpeg2000Options get(); 
   void set (    DicomJpeg2000Options value); 
}

Property Value

The JPEG 2000 compression options to use when compressing the image(s) in a Pixel Data element using the JPEG 2000 compression.

Example

This example will read a DICOM dataset, change its transfer syntax to JPEG-2000 and then save it back.

using Leadtools; 
using Leadtools.Dicom; 
 
 
public void TestChangeTransferSyntax() 
{ 
   string dicomFileName = Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "image3.dcm"); 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application 
   DicomEngine.Startup(); 
   using (DicomDataSet ds = new DicomDataSet()) 
   { 
      //Load DICOM File 
      ds.Load(dicomFileName, DicomDataSetLoadFlags.None); 
 
      DicomJpeg2000Options options = ds.DefaultJpeg2000Options;
