It is a common occurrence to see scaling being applied to bitmaps unnecessarily within Flash projects. Resizing bitmaps at runtime can be computationally expensive and degrades the image quality. Doing so can also result in a larger IPA file if the included artwork is actually larger than its intended display size.
Let us see how to resize existing bitmap artwork within Flash Professional.
From Flash Professional, open chapter4\recipe5\recipe.fla from the book's accompanying code bundle.
Again, you will be working with the familiar visuals from Chapter 2 and Chapter 3 example Bubbles application. The assets for this recipe are made up of both vectors and bitmaps. The bubbles themselves are vectors, whereas the background image and the Flash logo are bitmaps. The bitmaps have been scaled to fit the screen. To see the comparison in size between the scaled instances on the stage and the original bitmaps stored in the library, you may want to drag both background.png...
