[HTML5] Assets.getBitmapData() returns transparent BitmapData for JPG

var bd:BitmapData = Assets.getBitmapData("any.jpg");

Is this by design, or by accident? :slight_smile:

I think it is by design, otherwise you can’t modify the alpha layer using the BitmapData API, would be interesting how Flash works?

In Flash it is false for loaded JPGs and true for PNGs.
I wonder if non-transparent bitmaps are faster in copying/drawing?

Perhaps we should use true for embedded, but false for remotely loaded ones? The hard part is you can’t make it transparent without creating a copy

I don’t know…
But I think that most of the loaded JPGs aren’t used for transparency transformations…
