ImageRegion Property

Summary

Gets the RasterImage object that is updated with a shallow copy of the image that also has a region that contains the removed bumps and nicks.

Syntax

C#
VB
Java
Objective-C
WinRT C#
C++
public RasterImage ImageRegion { get; } 
Public ReadOnly Property ImageRegion As Leadtools.RasterImage 
public Leadtools.RasterImage ImageRegion {get;} 
@property (nonatomic, strong, readonly, nullable) LTRasterImage *imageRegion 
public RasterImage getImageRegion() 
 get_ImageRegion();  
public: 
property Leadtools.RasterImage^ ImageRegion { 
   Leadtools.RasterImage^ get(); 
} 

Property Value

The RasterImage object that is updated with a shallow copy of the image that also has a region that contains the removed bumps and nicks.

Remarks

If SmoothCommandFlags.SingleRegion | SmoothCommandFlags.LeadRegion has been set in the Flags property, then when SmoothCommand returns, this property is updated with a shallow copy of the image that also has a region that contains the removed bumps and nicks. So set Flags to SmoothCommandFlags.SingleRegion | SmoothCommandFlags.LeadRegion. It is the programmer's responsibility to dispose of the region when it is no longer needed.

Example

Run the SmoothCommand on an image.
