Class TGraphicsOperation

class TGraphicsOperation;

Description

Abstract base class for all graphics operations.

Derived classes encapsulate all the arguments needed by a given graphics operation. An object of one of the derived classes is passed as a parameter to CGraphicsAccelerator::Operation(). The member functions and enum defined in this class are not used directly in third party code.
