.NET GDI+: Drawing lines with rounded corners

Given an array of points, it is easy to draw a line based on these, e.g. using the GraphicsPath class. For instance, the following array of points... [0]: (0,0) [1]: (100,0) [2]: (0,100) [3]: (100,100) ...describes a line that resembles a Z. But here comes the challenge; I need to draw rounded corners with a radius of e.g. 10 pixels...

GraphicsPath doesn't always refresh itself

The simple curve in this application only appears when it's dragged off the screen, or the window is resized. When the application just starts up it doesn't appear, and when the window is maximized or minimized it also disappears. However, all of these times, "Path Drawn" is printed, so all of the painting functions are called. Is there ...

IronPython: Creating & Adding An Array Of Points To A GraphicsPath

Greetings; I'm having a bit of trouble correctly instantiating an Array of System.Drawing.Point instances, and then adding the Array of Points to a GDI+ GraphicsPath instance using IronPython in a WinForms application. The following code compiles or builds correctly under SharpDevelop 3.2 with IronPython 2.6: import System.Drawing imp...

How to create a clip region from a path that includes the 'outline'?

I am creating a rounded rectangle GraphicsPath (see red outline image below), and then using this as a clip region both when drawing graphics, and as the Region of a Form. Unfortunately, although the path looks good, it doesn't work well as a region (see solid black image below) Is there a way that I can generate a clipping region fro...

Can I determine the self-intersection points of a line created using the .NET C# GraphicsPath class?

I would like to create a line path using the GraphicsPath class in C#, consisting of multiple curves and lines. Would it be possible for me to determine any self-intersecting points of the class, and in the order that they appear? e.g. as an ordered array of points. ...

GraphicsPath - how to fill open figure (without closing it)

I have a big problem with filling an open GraphicsPath figure with Graphics.FillPath(brush, path). According to MSDN http://msdn.microsoft.com/en-us/library/kekf4cez.aspx 'the path is filled as if the open figure were closed by a straight line from its ending point to its starting point.' In this case figure similar to ie. 'e' drawn cre...

What's the opposite of polygon triangulation?

After I've done a 2D triangulation, some triangles have the same color and I want to recombine them for drawing into like-colored graphics paths. I find that if I just draw the triangles one by one, some graphic renderers shows seams between the triangles (at least if anti-aliasing and/or transparency is involved). So how do I take a se...
