  • Graphics Coordinates

    4D-AN-00058_R_1_0.pdf illustrates coordinate ranges for a 240x320 screen to be 0..240 and 0..320 implying a range of 241x321 pixels. Are the x,y coordinate arguments of graphics functions 0- or 1-based? 0..239 x 0..319 or 1..240 x 1..320 or ??

    Are graphics function arguments out-of-range safe?

    Thanks,
