Whats the best way to make a crosshair that is bounded by the size of the image box it is on top of? Its will be moved using a joystick. Its for the HUD of an ROV im working on. The crosshair needs to be able to return an x and y coordinate and its location to be determined by the joystick x and y axis value scaled to the size of the 640x480 pixel emguCV image box. Any ideas of how to approach this? I got the joystick part down but I don''t know what to use as the crosshair...
