GetNewViewPerspective(RasterViewPerspective,Double[],PlaneOrientation) Method

Summary

Gets a new RasterViewPerspective that results from applying a PlaneOrientation to a given RasterViewPerspective and two given direction cosine vectors.

Syntax

C++

public static Leadtools.RasterViewPerspective GetNewViewPerspective(  
   Leadtools.RasterViewPerspective viewPerspectiveOriginal, 
   double[] imageOrientationVectors, 
   Leadtools.Dicom.Common.Datatypes.PlaneOrientation po 
)

Public Overloads Shared Function GetNewViewPerspective( _ 
   ByVal viewPerspectiveOriginal As Leadtools.RasterViewPerspective, _ 
   ByVal imageOrientationVectors() As Double, _ 
   ByVal po As Leadtools.Dicom.Common.Datatypes.PlaneOrientation _ 
) As Leadtools.RasterViewPerspective

public: 
static Leadtools.RasterViewPerspective GetNewViewPerspective(  
   Leadtools.RasterViewPerspective viewPerspectiveOriginal, 
   array<double>^ imageOrientationVectors, 
   Leadtools.Dicom.Common.Datatypes.PlaneOrientation^ po 
)

Parameters

viewPerspectiveOriginal
The input RasterViewPerspective to which the PlaneOrientation will be applied.

imageOrientationVectors
The row and column orientation vectors (or direction cosine vectors) that apply to viewPerspectiveOriginal

po
A PlaneOrientation that is applied to the original RasterViewPerspective

Return Value

The new RasterViewPerspective that results from having the PlaneOrientation applied.

Remarks

The input view perspective is define by two values: the original RasterViewPerspective ( viewPerspectiveOriginal), and a row and column orientation vector ( imageOrientationVectors). This method returns the new RasterViewPerspective that results from applying a PlaneOrientation to the input view perspective.

Example

This example does the following:

Creates a coronal PlaneOrientation that corresponds to a horizontal flip
Defines orientation vectors that corresponds to a coronal slice

Applies the above to a view perspective, and returns the resulting view perspective
