Haxe NME DrawingStage

A multi-touch-friendly fullscreen drawing canvas made with a grid of bitmaps.

var grid = new BitmapGrid( width, height, cellSize, backgroundColor );
var brush = new BitmapBrush( bitmapData, color );

grid.fillRect( grid.rect, color );
grid.lineStyle( id, brush );
grid.moveTo( id, x, y );
grid.lineTo( id, x, y );
grid.clearStyle( id );
  • A cell size of 128px works best on mobile: the bottleneck on mobile is often the quantity of memory accessed during computations (bitmap drawing is CPU-bound) and performance collapses if you go over some threshold (it's related to L1 and L2 CPU memory cache sizes).

  • Compatible with all NME targets: Flash, HTML5, iOS, Android, desktop, neko.

  • Click/Tap the framerate indicator to clear the stage.
