Circle:
Circle(XPixelPosition, YPixelPosition, Radius [ [,Optional LineColour] [,Optional Rounding] ] )
Explanation:
Draws an unfilled circle on a GLCD centred at XPixelPosition, YPixelPosition with the given Radius.
The constant GLCD_PROTECTOVERRUN can be added to prevent circles from
re-drawing at the screen edges. Ensure the GLCD_WIDTH and GLCD_HEIGHT
constants are set correctly when using this additional constant.
Example:
#include <glcd.h>
circle(10,10,10) ;upper left
circle(117,10,10) ;upper right
circle(63,31,10) ;center ' <<< the Circle instruction
circle(63,31,20) ;center
circle(10,53,10) ;lower left
circle(117,53,10) ;lower rightKey line: circle(63,31,10) — draws a 10-pixel-radius unfilled circle centred at the middle of a 128x64 display.
