hi! i’m new to this forum 🙂

i have a problem with bitmaps… what i want to do is to preload some images, then multipy them on my scene ( the files are transparent png containing clouds )

the problem is that when i copy the bitmap data to create a new cloud, i loose transparency, and i can’t get WHY :cross-eye

here’s my code

```auto

public function Cloud( cloudLoader, seed ){ //constructor for the cloud
            var bitmap, bitmapData;
            this._speed = this.randomSpeed( ); //set a random speed for the cloud
            bitmap = cloudLoader.getContent( seed ); // returns a loader.content from one of the loaded images
            bitmapData = new BitmapData( bitmap.width, bitmap.height, true ); //create the bitmap data to copy into
            bitmapData.draw( bitmap ); //copy the data .. "bitmap" is a [DisplayObject (implements [URL="http://livedocs.adobe.com/flex/201/langref/flash/display/IBitmapDrawable.html"]IBitmapDrawable](http://livedocs.adobe.com/flex/201/langref/flash/display/DisplayObject.html) )
            this._cloud = new Bitmap( bitmapData ); // create a bitmap from the bitmap data
            this.addChild( this._cloud );
        }

```

in one of these passage i loose transparency…  
the cloudLoader.getContent is still transparent…  
the this.\_cloud is not transparent anymore

TIA :fab:
