Question

Basically what I am trying to do is make my drawing job easier.

Back in the days of VB6 there was something called Scalewidth and Scaleheight and I could set them to custom values. Ex. 100.

Then when I needed to draw a point at the center of the available space i would just draw it at 50,50.

Is there any way in .Net that I can get similar functionality?

So that no matter what the size of drawing canvas I get, I can draw on it using absolute co-ordinates.

I don’t know if there’s a way to achieve this in .NET, but you could easily implement this yourself:

// Unscaled coordinates = x, y; canvas size = w, h; // Scaled coordinates = sx, sy; Scalewidth, Scaleheight = sw, sh; x = (sx / sw) * w; y = (sy / sh) * h;  // Or the other way round sx = (x / w) * sw; sy = (y / h) * sh;
