)

ExtensionAttribute()
 function Leadtools.Dicom.Common.Extensions.DicomExtensions.GetNewViewPerspective(DicomDataSet,RasterViewPerspective,OrientationConfiguration)( 
   ds ,
   currentViewPerspective ,
   orientation 
)

[ExtensionAttribute()]
public:
static RasterViewPerspective GetNewViewPerspective( 
   DicomDataSet^ ds,
   RasterViewPerspective currentViewPerspective,
   OrientationConfiguration^ orientation
)

Parameters

ds: The Leadtools.Dicom.DicomDataSet that contains the image orientation vectors
currentViewPerspective: The input Leadtools.RasterViewPerspective to which the Leadtools.Dicom.Common.DataTypes.PlaneOrientation will be applied.
orientation: An Leadtools.Dicom.Common.DataTypes.OrientationConfiguration that will be applied to the current view perspective.

Remarks

This overload gets the image orientation vectors from the ds.

The input view perspective is defined by two values: the original Leadtools.RasterViewPerspective, and a row and column orientation vector (which are read from the ds by searching for the Leadtools.Dicom.DicomElement that has a tag of Leadtools.Dicom.DicomTag.ImageOrientationPatient which contains the orientation vectors.). This method returns the new Leadtools.RasterViewPerspective that results from applying a Leadtools.Dicom.Common.DataTypes.OrientationConfiguration to the input view perspective. Note that the orientation contains three lists of conditions (one for each 3D axis) that can be applied to the image contained in the ds if the condition is met.
