Working with BitmapData

[charlie_says]

I'm trying a few things with bitmapdata, and keep running up against the same problem, which is, that I can't use copyPixels/draw to "add" one bitmapData to another (both methods require an image from the game.cache or an HTML image).

 

Is there a way of adding bitmapdata to the cache? Or creating an HTML image that I can then use with the above methods?

Ok I read a bit more, and found

game.cache.addBitmapData('foo', barBMD );

but this doesn't work and generates the error:

 

Phaser.Cache.getImage: Invalid key: "foo"

Apologies for answering my own question, but just in case someone else might find it helpful.

 

The BitmapData object created has a number of properties, one being canvas, which means that you can copy (or manipulate) it  to an another BitmapData object.

var bmd1 = game.make.bitmapData(50, 50);var rect = new Phaser.Rectangle(0,0,50,50);bmd1.fill(255,0,0,1);bmd2.copyPixels(bmd1.canvas, rect, 20, 20);
