I am doing some image sampling. What my question is, is there a ‘crosshair’ tool in visual studio? I want to have several instances on a single form, be able to move them around and then sample those points, obviously returning the color of the pixel at the center of the crosshair, is there already a tool that will do this, before I go and write one?
Thanks, R.
I know of no crosshair, but the following procedure can be used twice to draw a crosshair. To remove it, simply draw it again as it uses XOR to make the procedure reversible.
