Declaration ​

pascal
TFlattenedPath = class(TCustomPath)

Description ​

TFlattenedPath extends TCustomPath to flatten mathematical curves (cubic Beziers, quadratic Beziers, arcs, circles, ellipses) into discrete polygonal vertex lines stored in dynamic float point arrays (TArrayOfArrayOfFloatPoint).

Key features include:

  • Tessellated Vertex Storage: Stores flattened vector path contours in the Path array (TArrayOfArrayOfFloatPoint) accompanied by closure state flags in PathClosed (TBooleanArray).
  • Path Lifecycle Events: Triggers OnBeginPath when starting a new sub-path and OnEndPath when completing a sub-path segment.
  • Dynamic Buffer Management: Utilizes internal vertex buffering with automatic grow strategies to minimize memory reallocations during curve tessellation.
