SmoothBitmap – How to ensure Bitmap pixel smoothing in AS3

A common oversight in Flash projects, when using a Bitmap with loaded content is that Flash will revert a Bitmap’s smoothing parameter to false when you replace its bitmapData. That is, when the data loads into the Bitmap, anti-aliasing will get turned off. This is simple enough to fix, but since you may not know if someone is going to replace the bitmapData of a Bitmap you have created – then it’s much better to code defensively for it.

This little SmoothBitmap class is for just such an occasion. Instantiate it like a regular Bitmap and, no matter what another developer does with it, smooth, anti aliased pixels when scaling/rotating will be ensured. Enjoy ­čÖé

Alternative titles for this post include:

  • Dependency Injection without a Dependency Injection framework
  • Why misusing the default namespace for tests is evil
  • Make code more testable without completely messing it up
