Java

Python

public LeadPointD Offset { get; set; }

@property (nonatomic, assign) LeadPointD offset;

public LeadPointD getOffset() 
public void setOffset(LeadPointD offset)

public:  
   property LeadPointD^ Offset 
   { 
      LeadPointD^ get() 
      void set(LeadPointD^ value) 
   }

Offset # get and set (AnnContainer)

Property Value

The offset of this AnnContainer in annotation units (1/720 of an inch). The default value is 0,0.

Remarks

In typical applications, you leave the offset of the container to 0,0.
