Summary

Interface to a TGPPathData object.

Description

Defines interface to a TGPPathData object.

The TGPPathData class is a helper class for the TGPGraphicsPath and TGPGraphicsPathIterator classes. A TGPGraphicsPath object has an array of points and an array of types. Each element in the array of types is a byte that specifies the point type and a set of flags for the corresponding element in the array of points. You can use a TGPPathData object to get or set the data points (and their types) of a path.

Properties

• Count - Returns the number of points.
• Points - Returns pointer to the data points.
• Types - Returns pointer to the data point types.

Methods

• function GetCount() : Integer - Returns the number of points.
• function GetPoints(Index : Integer) : TGPPointF
• function GetTypes(Index : Integer) : TGPPathPointType
