|Syntax|| drawarc (x, y, xRadius, yRadius : int, |
|Description|| The drawarc procedure is used to draw an arc whose center is at (x, y). This is just like drawoval, except that you must also give two angles, initialAngle and finalAngle, which determine where to start and stop drawing. Zero degrees is "three o'clock", 90 degrees is "twelve o'clock", etc. The horizontal and vertical distances from the center to the arc are given by xRadius and yRadius.|
|Example|| This program draws a semicircle (actually, an approximation to a semicircle) whose center is (midx,0) the bottom center of the screen, using color number 1. The maxx and maxy functions are used to determine the maximum x and y values on the screen.|
setscreen ("graphics") const midx := maxx div 2 drawarc (midx, 0, maxy, maxy, 0, 180, 1)
|Details|| The meaning of the Color number depends on the current palette. See the palette statement.|
The screen should be in a "graphics" mode. See the setscreen procedure for details. If the screen is not in a "graphics" mode, it will automatically be set to "graphics" mode.
