Width Property

Summary

Gets the width of this RasterImage in pixels.

Syntax

Objective-C

C++/CLI

Java

Python

public int Width { get; }

@property (nonatomic, assign, readonly) NSInteger width

public int getWidth();

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

Width # get  (RasterImage)

Property Value

The width of this RasterImage in pixels.

Remarks

This is the actual width of the image data scanline.

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