Hi, I'm writing a program that requires a camera, and
draw a few things on the image. It is pretty complicated, I have a
Application in java, that uses JNI to load a C program that draws the camera
image directly to a java "Canvas" object. Everything works great, excpet
one little thing. I am drawing an X/Y Axis and a circle over the camera,
and I have function to change the size of the circle, and the X/Y "tick"
size. Let's say that I change the circle from a diameter of 82 to a
diameter of 50, what happens on the screen is that it draws the 50 diameter
circle, and the 82 is still there. When I attempt to clear the display,
the lines are drawn properly, but I lose my v4l video that is being drawn on the
canvas. Is there any way I can clear out the lines, without afftecting the
the video?
