Jpeg2000Options Property (original) (raw)
Summary
Gets or sets the JPEG 2000 compression options.
Syntax
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.Dicom;

//In the whole application
