Function Reference


_GDIPlus_PathGetData

Gets an array of points and types from a path

#include <GDIPlus.au3>
_GDIPlus_PathGetData ( $hPath )

Parameters

$hPath Pointer to a GraphicsPath object

Return Value

Success: an array of points and types that specifies the endpoints and control points of the lines and bezier splines that are used to draw the path and the points types:
    [0][0] - Number of points and types
    [1][0] - Point 1 X position
    [1][1] - Point 1 Y position
    [1][2] - Point 1 type
    [n][0] - Point n X position
    [n][1] - Point n Y position
    [1][2] - Point n type
Each point type is one of the following values:
    0x00 - The point is the start of a figure
    0x01 - The point is one of the two endpoints of a line
    0x03 - The point is an endpoint or control point of a cubic bezier spline
    0x20 - The point is a marker
    0x80 - The point is the last point in a closed subpath (figure)
Failure: sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPID_ERR*).
