On the Horizon: JPEG2000 and Vector-Based Graphics

Two types of graphic formats on the horizon look promising: JPEG2000 and vector-based graphics.

The new JPEG2000 format is designed to be a superior replacement for the popular JPEG format. The JPEG2000 format uses wavelet technology to achieve higher compression ratios with radically reduced artifacts. The JPEG2000 format can compress images to 100:1 ratios or higher with much less image degradation than JPEGs. JPEG2000 also has a lossless compression option that typically achieves 3:1 to 4:1 compression. The JPEG2000 specification has been approved, but we won't see widespread use of this image format until browsers embed a JPEG2000 decompressor within their code.
