JPEG Compressor Roundup

Tags: , , , , , ,

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.

PNG, JPEG, and JPEG-XR Compression and Decompression Performance

Tags: , , , , ,

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.

Preloading Bitmap Decompression

Tags: , , ,

Since they were introduced way back in Flash Player 8, bitmaps have become a core feature in almost all Flash apps. The way you handle them—creation, operations, and destroying—is one of the most important factors determining your app’s performance. Today’s article shows one little-known trick to help out the performance of loading and using bitmaps.

Using ATF Is Harder Than You Might Think

Tags: , , , ,

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.

Compress ATF Textures By 95%

Tags: , , , , , ,

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.

ATF Texture Compression Image Quality and File Size Samples

Tags: , , , , , ,

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.
