PolyBezier(TPoint[])

Draws a set of Bezier curves.

Implements drawing cubic Bezier curves using the endpoints and control points specified by the Points parameter. The first curve is drawn from the first point to the fourth point, using the second and third points as control points. Each subsequent curve in the sequence needs exactly three more points: the ending point of the previous curve is used as the starting point, the next two points in the sequence are control points, and the third is the ending point. PolyBezier draws lines by using the current pen.

The Points parameter gives the endpoints to use when generating the Bezier curves. Control points after a[Index+3] are ignored. Nothing happens if there are not enough control points.
 

PolyBezierTo(TPoint[])

Draws a set of Bezier curves and updates the value of PenPos.

Implements drawing cubic Bezier curves using the endpoints and control points specified by the Points parameter. The first curve is drawn from the first point to the fourth point, using the second and third points as control points. Each subsequent curve in the sequence needs exactly three more points: the ending point of the previous curve is used as the starting point, the next two points in the sequence are control points, and the third is the ending point. PolyBezierTo draws lines by using the current pen and updates the value of PenPos to the value of the last endpoint.

The Points parameter gives the endpoints to use when generating the Bezier curves. Control points after a[Index+3] are ignored. Nothing happens if there are not enough control points.
 

Polygon(TPoint[])

Draws a series of lines on the canvas connecting the points passed in and closing the shape by drawing a line from the last point to the first point.

Implements drawing a closed, many-sided shape on the canvas, using the value of Pen. After drawing the complete shape, Polygon fills the shape using the current brush.

The Points parameter is an array of points that give the vertices of the polygon. The first point is always connected to the last point.

To draw a polygon on the canvas, without filling it, use the Polyline method, specifying the first point a second time, at the end.

Polyline(TPoint[])

Draws a series of lines on the canvas with the current pen, connecting each of the points passed to it in Points.

Implements connecting a set of points on the canvas. If you specify only two points, Polyline draws a single line.

The Points parameter is an array of points to be connected.

Calling the     MoveTo function with the value of the first point, and then repeatedly calling     LineTo with all subsequent points will draw the same image on the canvas. However, unlike LineTo, Polyline does not change the value of PenPos.

Rectangle(Integer,Integer,Integer,Integer)

Draws a rectangle on the canvas.

Implements drawing a rectangle using the pen and filling it with the current brush.

To fill a rectangular region without drawing the boundary in the current pen, use FillRect. To outline a rectangular region without filling it, use FrameRect or Polygon. To draw a rectangle with rounded corners, use RoundRect.
