Hi everyone,<br><br>I have a problem that I wonder if someone can help me with.<br><br>I have an image and when I press the left button and drag the mouse, I want to calculate the angle that the subsequent mouse positions describe from the center of the image. So, given x1, y1 and x2, y2, can someone tell me how I can calculate the angle between them...
<br><br>Thanks and cheers,<br><br>Anja<br>
