draw

I am tryin to draw a genealogy tree. In my tree, I store information about ex partners. So the Panel (Region) for person shoud looking like this Z * * * Z * * * Z * * * X --- Y Where Z represent exPartner, X represent Persion and Y represent current Wife / Husband And now I would like to draw line to connect current relation with children. And ec relations with children. (graphicaly there will be a line beetwen Z and *) But when the person is in the other region LayoutX and LayoutX property return relative value. How Can I do that, and how dynamicaly resize this Panel ? I would like that Z

i tried in that way but i didnt get the needed results: System.Drawing.Point[] p = new System.Drawing.Point[6]; p[0].X = 0; p[0].Y = 0; p[1].X = 53; p[1].Y = 111; p[2].X = 114; p[2].Y = 86; p[3].X = 34; p[3].Y = 34; p[4].X = 165; p[4].Y = 7; g = PictureBox1.CreateGraphics(); g.DrawPolygon(pen1, p); what i want to do is to draw a polygon in picturebox which is defined with diffrent colors and according to the rates (the number of corner and coordinates of the edges ) Create an xOffset variable, set it to be 30, and add that to every X value. Let yOffset equal 50 and add it to all your Ys.

I want to build a tool on Android where the user can paint some simple objects over a picture (eg line, circle or arrow). I started trying the line part first, and indeed I could succeed on painting it. The logic is that the user taps at one point and then drags their finger, painting the line. I use a class like this (it is based on DonGru's answer here ): public class DrawView extends View { Paint paint = new Paint(); float Sx, Sy, Lx, Ly; public DrawView(Context context, float x1, float y1, float x2, float y2) { super(context); paint.setColor(Color.RED); Sx=x1; Sy=y1; Lx=x2; Ly=y2; }

I have pixel art creator program, and I have rectangles on canvas that are one field (pixel?). And this is good solution on not huge amount of it (for example 128x128). if i want to create 1024x1024 rectangles on canvas this process is very long, ram usage is about 1-2 gb and after that program runs very slowly. How to optimize this, or create better solution? Using a Rectangle to represent each pixel is the wrong way to do this. As a FrameworkElement , every rectangle participates in layout and input hit testing. That approach is too heavy weight to be scalable. Abandon it now . I would
