Description

The GR32_ArrowHeads unit provides a set of classes for generating 2D vector arrowhead shapes along lines and polylines. These shapes can be rendered onto a TCustomBitmap32 surface using polygon filling or stroking functions.

Key components in GR32_ArrowHeads include:

Kind	Example	Class	Description
3-Point		TArrowHeadSimple	Generates a standard 3-point triangular arrowhead.
4-Point		TArrowHeadFourPt	Generates a 4-point dart/barbed arrowhead.
Circle		TArrowHeadCircle	Generates a circular endpoint decoration.
Diamond		TArrowHeadDiamond	Generates a 4-point diamond endpoint decoration.
