Height Property

Summary

Gets the height of this RasterImage in pixels.

Syntax

Objective-C

C++/CLI

Java

Python

public int Height { get; }

@property (nonatomic, assign, readonly) NSInteger height

public int getHeight();

public: 
property int Height { 
   int get(); 
}

Height # get  (RasterImage)

Property Value

The height of this RasterImage in pixels.

Remarks

This is the actual number of scanlines of image data.

Use ImageHeight to get the height of the image taking the ViewPerspective into account. For more information refer to Accounting For View Perspective.
