TransformBase Class Reference

The Transformation Base Class. This is an abstract class - you can only create instances of its derived classes. The Transformation classes are used to give a transparent interface to arbitary transformations on objects. Nodes do not need to be aware of what type of transformation is being applied or how is should be undone. This class contains two virtual function :- MonoOn virtual void Transform(DocCoord* Coords, INT32 NumCoords) MonoOff MonoOn virtual BOOL IsInvertable() MonoOff It also contains the following public member vars MonoOn BOOL TransLines; // TRUE if Line Widths are to be transformed MonoOff MonoOn BOOL TransFills; // TRUE if Fills are to be transformed MonoOff.

Public Member Functions

 TransformBase ()
virtual void Transform (DocCoord *Coords, INT32 NumCoords)=0
virtual BOOL IsInvertable ()=0
virtual BOOL IsTranslation ()
virtual FIXED16 GetScalar ()
 Returns the Transforms idea of the equivalent scale factor for the transform. This is mainly used to help with the scaling of line widths to save them trying to extract the scale factor from the matrix.
