I recently stumbled upon an old bit of code which demonstrates a technique I created for an efficient scrolling data grid on the YouView TV platform. I call it ‘Blit Scrolling’. Below is a demo of the concept – click on the window and use the arrow keys to scroll around (Flash required):

How to verify that something implements an interface with Mockito
If you want to write a unit test which verifies that something implements a particular interface, or extends a particular class, here’s how…

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 🙂
