| Comments |
Support for compressed BMP is rare |
Complex data element structure often introduces
minor incompa-tibilities between vendors |
For simple diagrams, GIF often compresses better
than others |
Support for lossless JPEG compression is rare |
JPEG 2000 has yet to garner widespread support |
Fully open standard designed to replace GIF
and TIFF |
Proprietary format used in Adobe® Photoshop® |
Support for lossy TIFF compression is rare |
1 The star rating system is based on relative
differences of compression performance to other formats, rather than an
absolute performance ranking. A single star difference does not indicate
a magnitude of improvement, but rather a noticeable improvement in general.
