    XMLWordPrintable

    Details

      Description

      In the drawing interaction:

      • Implements the event handling for pointer events API
      • Optimise canvas drawing and dropped same points
      • Optimise drawing on the canvas by using "requestAnimationFrame"
      • Prevent double stop which results in drawing twice a circle or an other form (can be seen if the circle is transparent)
      • Remove listener on document element or after using them

      Important: check that the menu "More" still works after playing with the drawing interaction
