TIEPolylineLayer.SetPoint
Declaration
procedure SetPoint(Index: integer; X, Y: integer; PointBase: TIEPointBase = iepbRange; SnapAngles: Boolean = False); overload;
procedure SetPoint(Index: integer; X, Y: integer; PointBase: TIEPointBase; Action: TIEPathAction; ClosePath: Boolean = False;
CurveX1: Double = 0; CurveY1: Double = 0; CurveX2: Double = 0; CurveY2: Double = 0;
ArcLarge: Boolean = False; ArcSweepCW: Boolean = False); overload;
Description
Sets the point of the specified index.
Each point of the polyline is represented by an x and y value in the range 0 to 1000. Where (0, 0) is the top-left pixel of the layer and (1000, 1000) is the bottom-right. Values less than 0 or more than 1000 will increase the size of the layer.
There is also a
complex path overload that allows you to add curves and arcs.
Parameter | Description |
X, Y | The point to add |
PointBase | What base units point values are specified in |
SnapAngles | Set to true to adjust the angle to ensure it aligns with LayersRotateStep (e.g. force it to 45 deg. steps) |
Complex Path Notes:
◼For an iepaBezierCurveTo you must set: CurveX1, CurveY1, CurveX2, CurveY2
◼For an iepaQuadraticCurveTo you must set: CurveX1, CurveY1
◼For an iepaArcTo you must set: CurveX1 (= ArcRadiusX), CurveY1 (= ArcRadiusY), CurveX2 (= ArcRotation), ArcLarge, ArcSweepCW
// Set second point at 500, 0
TIEPolylineLayer( ImageEnView1.CurrentLayer ).SetPoint( 1, 500, 0 );
ImageEnView1.Update();
// Set the second point that will double the width of the layer
TIEPolylineLayer( ImageEnView1.CurrentLayer ).SetPoint( 1, 130, 2000 );
ImageEnView1.Update();
// Set a point representing the arc in the following path: <path fill="#0c64d2" d="M49 58 A42 42 10 1 0 50 58z"/>
TIEPolylineLayer( ImageEnView1.CurrentLayer ).SetPoint( 1, 50 58, iepbBitmap, iepaArcTo, True, 42, 42, 10, True, False );
ImageEnView1.Update();
