- Up to 50% higher decompression throughput than version 1.1 (improvement largest for colour images). Version 1.1 itself had substantially higher throughput than the VM, Jasper and JJ2000.
- Data processing uses either 16- or 32-bit, fixed or floating-point representations, depending on the task at hand. Two different fixed-point processing strategies are demonstrated in the code.
- You can now extract, reconstruct or interactively select individual image components from a code-stream.
- You can now interactively select the number of quality layers used to reconstruct images within the "kdu_show" application.
