Having covered JPEG-XR images recently, one thing has struck me as a little odd: there aren’t really any good cross-platform viewers available to look at them. Yes, it’s a bit of an obscure format, but shouldn’t there be something available? Well, I decided to make a simple Flash app to load a JPEG-XR image from a URL or a browse button and display it. Along the way I added support for PNG, JPEG, GIF, AVM1 SWF, and AVM2 SWF. Today’s article has the source code and the viewer itself. Added support for panning the image

Now that we’ve determined the best PNG compressors to create PNG images with, let’s delve into the world of JPEG compressors. As with PNG, we have multiple options to choose from in our Flash apps when we’re looking to encode images such as screenshots. Which is best? Today’s article delves into each compressor’s performance and file size efficiency.
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.
Are you using the fastest assets you can? Yes, even the file format of the assets you use has a big bearing on the performance of your app. Ask yourself: is PNG faster to decompress than JPEG? Is it faster to compress to JPEG-XR or PNG? Do the quality settings matter? Today’s article explores the performance of Flash’s main three image formats—PNG, JPEG, and JPEG-XR—to find out which decompresses fastest at load time and compresses fastest at save time.
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.
