I’m allowed to use only get(), background() methods and color data type.  
How can I check that the given pixel (x,y), is background colored(black) or not ?  
I can’t figure it out from the references.

Use

color c1=get(x,y);

if(c1!=color(0))

Thank you it works! But with the default color of the point, which is 30 and not black. It’s my bad.
