FromAnnContainerToDataSet(DicomDataSet,DicomElement,AnnContainer,FromAnnContainerToDataSetOptions) Method

Summary

Converts all the LEAD Annotation objects in an AnnContainer into one or more DICOM annotation objects, and adds (overwrites or appends) the result in a Leadtools.Dicom.DicomDataSet.

Syntax
C#
C++/CLI

Parameters

ds

The Leadtools.Dicom.DicomDataSet where the resulting DICOM Annotation objects are stored.

graphicAnnotationSequenceItem

The specific Leadtools.Dicom.DicomElement where the resulting DICOM Annotation objects are stored.

annContainer

The Leadtools.Annotations.Engine.AnnContainer that contains a list of Leadtools.Annotations.Engine.AnnObject objects that are to be converted.

options

options that determine if annotations are appended to existing ds, or if ds is overwritten.

Return Value

A Leadtools.Dicom.DicomDataSet of type DicomUidType.GrayscaleSoftcopyPresentationStateStorage containing all the annotations in annContainer.

Remarks

This method converts a LEAD Leadtools.Annotations.Engine.AnnContainer of Leadtools.Annotations.Engine.AnnObject objects into one or more DICOM annotation objects (text, graphic, and compound graphic), and stores (overwrites or appends) the result inside the ds parameter.

If the resulting DICOM annotation object is:

  • Compound Graphic , it will be added under the Compound Graphic Sequence and for backward compatibility (as per the DICOM Specification) it will also be added under the Graphic Object Sequence.
  • Text Object , it will be added under the Text Object Sequence.
  • Graphic Object , it will be added under the Graphic Object Sequence.

The dsImage is a Leadtools.Dicom.DicomDataSet that contains an image on which the annotations are to be rendered.

Patient, Study, and series information is copied from dsImage and stored in the resulting ds, including:
