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#
VB
C++
Public Overloads Shared Function GetNewViewPerspective( _ 
   ByVal viewPerspectiveOriginal As RasterViewPerspective, _ 
   ByVal imageOrientationVectors() As Double, _ 
   ByVal po As PlaneOrientation _ 
) As RasterViewPerspective 

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
