Using Adobe’s new compressed texture format should be as simple as replacing some PNG and JPEG images with ATFs their tools created, but it’s not. If you don’t know what you’re doing, the process can be pretty confusing. Today’s article walks you through the steps to upgrade a Stage3D-using app to make use of ATF textures.

ATF textures already contain a lot of compression: DXT, ETC, or PVRTC texture compression plus JPEG-XR and LZMA for good measure. What more can we do? As it turns out, we can drastically reduce the file size by simply applying Zlib or LZMA compression to the files. Read on for some samples with file size breakdowns.
Adobe’s newly-released ATF tools have introduced an all-new image file format: ATF, the Adobe Texture Format. It’s not every day we get a new image format. After all, PNG was introduced in 1996 and JPEG in 1992. For various reasons I discussed last week, you probably have good reasons to use this new image format. So let’s dive into it a bit and see what kinds of images it produces.
Adobe has recently released tools to allow us to use compressed textures with the Stage3D API via their ATF tools. What are these compressed textures? Why would we want to use them? How do they work? Today’s article is an overview of compressed textures covering these questions and more.
