Leadtools.Dicom Namespace > DicomDataSet Class : Jpeg2000Options Property



Gets or sets the JPEG 2000 compression options.

Syntax

Visual Basic (Declaration) 
Public Property Jpeg2000Options As DicomJpeg2000Options
Visual Basic (Usage)Copy Code
Dim instance As DicomDataSet
Dim value As DicomJpeg2000Options
 
instance.Jpeg2000Options = value
 
value = instance.Jpeg2000Options
C# 
public DicomJpeg2000Options Jpeg2000Options {get; set;}
C++/CLI 
public:
property DicomJpeg2000Options Jpeg2000Options {
   DicomJpeg2000Options get();
   void set (DicomJpeg2000Options value);
}

Return 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.
