Bug 122115 – Don't attempt to destroy decoded frame if a BitmapImage doesn't have encoded raw data.

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Yongjun Zhang]

With BitmapImage::create(PassNativeImagePtr, ImageObserver*), a BitmapImage could be created by passing a native image.  If this image is added to memory cache, we shouldn't attempt to destroy its decoded frames since there is no encoded raw data and we won't be able to reconstruct the image again.

Nit: "added to memory cache" => "added to the memory cache"

Nit: This line should come after the bug URL.

The second sentence doesn't read well. Maybe:

Currently there isn't a code path to add to the memory cache a BitmapImage that was created by adopting a native image. We'll add such a code path in a subsequent patch.
