Fun with Circles


It doesn’t do a great deal other than generate circle arcs or segments, but does demonstrate how to:

 

 

 

  • Draw an arc on a canvas – uses the for each number rather than a timer, seems to work much faster – see “DrawSegment” procedure, 2nd if/then
  • Draw a segment on a canvas
  • Rotate a segment on a canvas – 0 degrees may not be where you want it
  • Change colour of segments
  • Save canvas to image
  • Use of spinner hack to always use top selection on display
