ViewPerspective Property

Summary

Gets or sets the view perspective of the image data of this RasterImage.

Syntax

Objective-C

C++/CLI

Java

Python

public RasterViewPerspective ViewPerspective { get; set; }

@property (nonatomic, assign) LTRasterViewPerspective viewPerspective

public RasterViewPerspective getViewPerspective();

public: 
property RasterViewPerspective ViewPerspective { 
   RasterViewPerspective get(); 
   void set (    RasterViewPerspective ); 
}

ViewPerspective # get and set (RasterImage)

Property Value

The view perspective of the image data of this RasterImage.

Remarks

The view perspective indicates where the beginning of the image is stored. For more information, see RasterViewPerspective.

For more information refer to Accounting For View Perspective.

Note: You should be careful when setting the view-perspective of an image using this property since it will not change the orientation of the data of the image. To do that, use ChangeViewPerspective.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
 
 
public void ChangeViewPerspectiveCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
 
	// Load the source image from disk 
	RasterImage image = codecs.Load(srcFileName); 
 
	// Check the view perspective 
	Console.WriteLine("Original view perspective = {0}", image.ViewPerspective); 
 
	// If the view perspective is TopLeft, change to BottomLeft and vise versa 
	RasterViewPerspective viewPerspective = image.ViewPerspective; 
	if (viewPerspective == RasterViewPerspective.TopLeft) 
		viewPerspective = RasterViewPerspective.BottomLeft; 
	else 
		viewPerspective = RasterViewPerspective.TopLeft; 
 
	// Change the image view perspective 
	ChangeViewPerspectiveCommand command = new ChangeViewPerspectiveCommand(); 
	command.ViewPerspective = viewPerspective; 
	command.InPlace = true; 
 
	command.Run(image); 
 
	// Re-check the view perspective 
	Console.WriteLine("New view perspective = {0}", image.ViewPerspective); 
	Assert.IsTrue(image.ViewPerspective == viewPerspective); 
 
	// Clean up 
	image.Dispose(); 
	codecs.Dispose(); 
}
