ChangeViewPerspective Method

Summary

Rotates and flips the image data as necessary to achieve the desired view perspective.

Syntax

Objective-C

C++/CLI

Java

Python

public void ChangeViewPerspective( 
   RasterViewPerspective viewPerspective 
)

- (BOOL)changeViewPerspective:(LTRasterViewPerspective)viewPerspective error:(NSError **)error

public void changeViewPerspective( 
   RasterViewPerspective viewPerspective 
);

public: 
void ChangeViewPerspective(  
   RasterViewPerspective viewPerspective 
)

def ChangeViewPerspective(self,viewPerspective):

Parameters

viewPerspective
Desired view perspective.

Remarks

The ViewPerspective is the arrangement of pixels in the image. This method references image coordinates, which are often different from the display coordinates of an image.

Use this method to change the data and the ViewPerspective to simplify calculations that involve image coordinates. This method does not affect the image display. For more information, refer to Accounting for View Perspective.

The following values for viewPerspective are supported in (Document/Medical only) only:

RasterViewPerspective.RightTop
RasterViewPerspective.TopLeft90
RasterViewPerspective.LeftBottom
RasterViewPerspective.TopLeft270
RasterViewPerspective.LeftTop
RasterViewPerspective.BottomLeft90
RasterViewPerspective.RightBottom
RasterViewPerspective.BottomLeft270

Example

This example demonstrates the low-level methods for accessing 1-bit compressed image data. It demonstrates the ability to get and put rows, and the ability to process rows in buffer-to-buffer processing. The result of the function is an the first 50 lines are inverted.
