Detailed Description

This interface expose APIs for basic and advanced geometry calculation functionalities.

To use this interface, you should create a LGeomOp object.

Example Code

C++

ILGeomOpPtr geomOp = LGeomOp::Create();
ILRectPtr resultRect = geomOp->InnerRect(mask);
ILRectPtr resultSquare = geomOp->InnerSquare(mask);

C#

LGeomOp geomOp = new LGeomOp();
LRect resultRect = geomOp.InnerRect(mask);
LRect resultSquare = geomOp.InnerSquare(mask);

COM

ILGeomOpPtr geomOp = LGeomOp::Create();
// or, ILGeomOpPtr geomOp(__uuidof(LGeomOp)), for absence of built-in Create functions (before 2.2.0)
ILRectPtr resultRect = geomOp->InnerRect(mask);
ILRectPtr resultSquare = geomOp->InnerSquare(mask);
