'''Class:''' [[Interface IGDIPlus.IGPGraphicsPath|IGPGraphicsPath]]

== Syntax ==
=== Delphi: ===
<code>
'''function''' GetPathData() : [[Interface IGDIPlus.IGPPathData|IGPPathData]];
</code>

=== C++ Builder: ===
<code>
[[Interface IGDIPlus.IGPPathData|IGPPathData]] '''__fastcall''' GetPathData();
</code>

=== Visual C++ (MFC): ===
<code>
GetPathData();
</code>

== Summary ==
Returns an [[Interface IGDIPlus.IGPPathData|IGPPathData]] interface to object containing an array of points and an array of point types from this path.

== Description ==
Call this method to get an [[Interface IGDIPlus.IGPPathData|IGPPathData]] interface to object
containing an array of points and an array of point types
from this path. Together, these two arrays define the lines,
curves, figures, and markers of this path.

Example:

The following example creates and draws a path that has a
line, a rectangle, an ellipse, and a curve. The code gets the
path's points and types by passing the address of a PathData
object to the GetPathData method. Then the code draws each of
the path's data points.

<code>

AGraphics : [[Interface IGDIPlus.IGPGraphics|IGPGraphics]];
APath : [[Interface IGDIPlus.IGPGraphicsPath|IGPGraphicsPath]];
APathData : [[Interface IGDIPlus.IGPPathData|IGPPathData]];
ABrush : [[Interface IGDIPlus.IGPPen|IGPPen]];
I : Integer;

begin
AGraphics := [[Class IGDIPlus.TGPGraphics|TGPGraphics]].Create( ACanvas );
APath := TGLPath.Create();

Remarks
A [[Interface IGDIPlus.IGPGraphicsPath|IGPGraphicsPath]] 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. Possible point
types and flags are listed in the [[Enum IGDIPlus.TGPPathPointType|TGPPathPointType]]
enumeration.
