在as3 Starling中放置纹理

Question

I am currently working on an application where a screenshot of the stage is generated as bitmap image and the generated image is then added to a tab in the application.

I am unable to add more than a few screenshot images to the tab. The application throws "Error #3691: Resource limit for this resource type exceeded" exception.

I found that this exception is thrown because of the texture not being disposed properly. In the code below, If I dispose the bufferedTexture, the image added to the tab is empty.

Below is the code:

public function AddtoMediaTab():void
{
   var buffer:BitmapData;
   buffer = GetStageAsBitmapData();
   var bufferedTexture:Texture = Texture.fromBitmapData(buffer);
   this.image.source = bufferedTexture;
   buffer.dispose();
   buffer = null;
  //bufferedTexture.dispose(); 
  //bufferedTexture = null;
}

public function GetAsBitmapData():BitmapData
{
    var buffer:BitmapData = new BitmapData(this.width,this.height, false, 0x000000);
    this.media.DrawToBitmap(buffer);
    return buffer;
}

Any help is appreciated.

Thanks

You could try changing the rendering profile. Straight from the Starling API documentation:

starling.core.Starling API

Context3D Profiles

Stage3D supports different rendering profiles, and Starling works with all of them. The last parameter of the Starling constructor allows you to choose which profile you want. The following profiles are available:

• BASELINE_CONSTRAINED: provides the broadest hardware reach. If you develop for the browser, this is the profile you should test with.
• BASELINE: recommend for any mobile application, as it allows Starling to use a more memory efficient texture type (RectangleTextures). It also supports more complex AGAL code.
• BASELINE_EXTENDED: adds support for textures up to 4096x4096 pixels. This is especially useful on mobile devices with very high resolutions.

The recommendation is to deploy your app with the profile "auto" (which makes Starling pick the best available of those three), but test it in all available profiles.
