Question

I have a drawn a Circle Shape in AS3. I want to render the Circle into a Bitmap with nice/antialiased Edges. Because I want it to work on Mobile Devices (Air Apps are limited to stagequality = low) I need a workaround. Any custom shape to bitmap renderer available?

Answer 1

Not sure this solution would work for Air Mobile Apps, but worth looking into.

Didier Brun @ ByteArray.org posted an API used to draw primitive shapes (as BitmapData, not from Vector draw calls either), which might help you get your circles to draw the way you want.

http://www.bytearray.org/?p=67

Code Snippet (from that URL):

// create the BitmapData to work on
var pixels:Raster = new Raster(320, 240, true);

// draw stuff
pixels.drawRoundRect( new Rectangle ( 20, 20, 200, 100), 18, 0xFF00FFFF );
pixels.drawRect( new Rectangle ( 70, 70, 100, 100 ), 0xFF009900 );
pixels.filledTri( 40, 40, 80, 110, 50, 30, 0xFF998811 );
pixels.aaCircle(100, 100, 40, 0x77AA88 );
pixels.circle(40, 40, 30, 0xFF000000);
pixels.line(10, 10, 60, 80, 0xFF000000 );

// show it
addChild ( new Bitmap ( pixels ) );

Hopefully the library / source code is compatible for your project! 🙂
