Python

public ChangeViewPerspectiveCommand( 
   bool inPlace, 
   RasterViewPerspective viewPerspective 
)

- (instancetype)initWithInPlace:(BOOL)inPlace  
                viewPerspective:(LTRasterViewPerspective)viewPerspective

public ChangeViewPerspectiveCommand( 
   boolean inPlace,  
   RasterViewPerspective viewPerspective 
)

public: 
ChangeViewPerspectiveCommand(  
   bool inPlace, 
   RasterViewPerspective viewPerspective 
)

__init__(self,inPlace,viewPerspective) # Overloaded constructor

Parameters

inPlace
true to convert the source image in place (no copy will be made). false, to leave the source image unchanged and place the result in the DestinationImage property.

viewPerspective
The desired view perspective.

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(); 
}
