Hi
First of all you should know the relation between the logical coordinates and the device coordinates (pixels).
For example if you have a DC that is 20 x 20 pixels, and you would like it to be, lets say, 50 x 50 units (for your personal purpose) you should specify something like:

SetViewportExtEx (hDC, 20, 20, NULL);
SetWindowExtEx (hDC, 50, 50, NULL);

You can set or offset the origin either in the window (logical coordinates) or in the viewPort (device coordinates) or in both.
