Drawing tapered lines programatically in c#
0
is it possible to draw curved tapered lines with c# via code?
i am able to draw curved lines like this:
var g = panel1.CreateGraphics();
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
var p = new Pen(Color.Black);
var sb = new SolidBrush(Color.Red);
PointF points = new PointF {
new PointF(1,0),
new PointF(100,0),
new PointF(200,100),
new PointF(400,0),
};
g.DrawBeziers(p,points);
but this way i cannot set different widths.
that is what i want to achieve

No, there is nothing built-in to produce such an effect. Note that it would need quite a few parameters to define the changing angles. You can create a 2nd bezier and fill a pth but the calculation of good looking coordinates is not always trivial.. Best make use of graphics rotations.

Ok, it was easy once i knew what i had to do:
draw 2 lines and fill the space between:
var g = panel1.CreateGraphics();
g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
PointF points1 = new PointF {
new PointF(0,0),
new PointF(100,150),
new PointF(500,0),
//new PointF(400,0),
};
PointF points2 = new PointF {
new PointF(0,0),
new PointF(100,160),
new PointF(500,0),
//new PointF(400,0),
};
panelPath = new GraphicsPath();
panelPath.AddCurve(points1);
panelPath.AddCurve(points2);
g.FillPath(Brushes.Black, panelPath);
