flash.sampler.getSize() is a handy tool for figuring out how much memory a class instance uses. However, it is often flat-out wrong. Today’s article tries it out on a variety of classes to find out which ones it works on and which ones it doesn’t.

In almost all circumstances,
Stage3D requires you to provide textures with power-of-two dimensions. This is often inconvenient as most images are not already sized that way. Today’s article provides a simple class to easily build a texture with power-of-two dimensions. An example app is also provided.
Flash makes it pretty easy to use any
DisplayObject as a
Stage3D texture. This is a great feature since you can use powerful, traditional classes like
Shape to build a texture—often with vector graphics—and then use
Stage3D‘s GPU hardware acceleration to render them with maximum performance. But this path is fraught with subtle problems, any one of which could result in poor rendering quality that’s quite hard to debug. Today’s article takes you through the process step by step to make sure you end up with great results.
HTML5 is all the rage and a lot of Flash developers are either curious about it or have actually made the switch. But how does its performance stack up against Flash? That is a very complicated question, so we’ll begin today with just a simple test of the speed at which a lot of bitmaps can be drawn to the screen. Who will win? Read on to find out.
Flash Player has had built-in PNG compression since version 11.3. But how does it fare against all of the other PNG compressors out there? Does it compress faster? Does it produce smaller file sizes? Today’s article explores your options when it comes to compressing PNG files so you can get the fastest or smallest PNG possible.
Which image format is fastest to load? That was perhaps the most relevant question in last week’s article, so it’s time to explore it more deeply. Today’s article examines differences between different types of PNG, JPEG, and JPEG-XR files to answer questions like “does the JPEG quality setting matter?” and “is indexed PNG faster than full (ARGB) PNG?” Read on for the test and all the details.
