ClipBounds Property

Gets or sets the clipping rectangle, in pixel coordinates.
public LeadRectD ClipBounds { get; set; } 
@property (nonatomic, assign) LeadRectD clipBounds; 
public LeadRectD getClipBounds() 
public void setClipBounds(LeadRectD clipBounds) 
property LeadRectD ClipBounds { 
   LeadRectD get(); 
   void set (    LeadRectD ); 
ClipBounds # get and set (SvgRenderOptions) 

Property Value

The clipping rectangle, in pixel coordinates. The default value is LeadRectD.Empty.


The engine will apply this clipping into Bounds to exclude all or parts of the objects that do not fit. The transformation set in SvgRenderOptions.Transform will not be applied to this rectangle. If this value is an empty Leadtools.LeadRectD or has 0 width and 0 height, then an Empty rectangle will be used to render the entire document and no clipping performed.
