Quoting from the api docs:
>public abstract int getWidth(ImageObserver observer)
> Gets the actual width of the image. If the width is not known yet then
>the ImageObserver will be notified later and -1 will be returned.
How is the imageobserver 'notified later'? Is a function called like
"observer.ImageIsLoaded(img)" ?
Is this like a callback...?
tia!
