| Format | 'ARC'(x,y,radius,aspect,angle_1,angle_2) Where: |
|
| angle_1 | Starting angle, in degrees. Numeric expression. | |
| angle_2 | Ending angle, in degrees. Numeric expression. | |
| aspect | Aspect ratio / viewpoint. (Ratio=1 results in no tilt.) Numeric expression. | |
| radius | Radius of the circle, in graphical units. Numeric expression. | |
| x,y | Coordinates for the centre of the drawing, in graphical units. Numeric expression. | |
| Description | Use 'ARC' to draw (print) an arc on the device. Use graphical units or @X(col) and @Y(line) functions for x, y, and radius. The arc will extend from the starting angle1 to angle2. The 'ARC' mnemonic uses the current 'PEN' attributes. |
|
| Example | The example below draws two different-coloured arcs. Aspect ratio=3 tilts the resulting drawing into an elliptical "shape". (Since this ellipsis is really two arcs as opposed to an enclosed shape, 'FILL' attributes do not apply.) Aspect ratio=1 would join the arcs in a circular shape instead. 0060 PRINT 'PEN'(1,3,1) 0070 PRINT 'ARC'(800,250,75,3,1,75) 0080 PRINT 'PEN'( 0090 PRINT 'ARC'(800,250,75,3,75,1) |
