[...] First snag: Flex doesn’t seem to offer a straightforward way of identifying a repeatable background for the Canvas class. Quick searching revealed that one can do this with Degrafa, but I didn’t want to go that route. (Not that Degrafa isn’t tremendous, it just seems like a lot of overhead just to tile a background image.) There is another solution for setting a tiled image as a background. [...]

Thanks Alex. This is exactly what I needed.

Keep up the great work.

Hey Deke,

To set the transparency, go to line 24 in TileImageCanvas.mxml, you should see this:

var bitmapData : BitmapData = new BitmapData( bitmap.width, bitmap.height );

Change it to:

var bitmapData : BitmapData = new BitmapData( bitmap.width, bitmap.height, true, 0×00000000 );

That should work : )

I love this, but curiously- it doesn’t appear to support alpha transparency of my tile images. I’m using transparent png-24 files for an image tile, and the transparent portions of the image appear white.

Any suggestions that might point me to a solution for supporting transparency in my tiles?

Thanks.

This is perfect. All other solutions that I’ve seen require embedding the image at runtime.

I tested it out and it works like a charm.

MUCH appreciated!!
