Differences between Image and BitmapImage with Fle

Question

In Image's asdoc, we can see :

Flex also includes the BitmapImage class. This class is used for embedding images into skins and FXG components

but we can also use Image in skins and use @Embed with Image...

Therefore, where and when should I use Image or BitmapImage please ?

Answer 1

Image is a skinnable class that wraps BitmapImage. As such BitmapImage is more lightweight, but Image has more features. So the question when to use which boils down to this:
if the features of BitmapImage suffice, use that; otherwise use Image. Especially in mobile environments try to favor the use of BitmapImage.

Now what features does Image add exactly?

• Image extends SkinnableComponent: this means you can assign your images a skin with a border or a dropshadow or whatever you like consistently throughout your application.
• It also provides a progress indicator which can be displayed while the image is loading.
• One more feature is the possibility to queue the loading of multiple images.
