Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit JPGs are a lossy compression format. Zipped BMPs would be a better way to go since BMPs aren't lossy and would still be compressed. Plus the mask could be zipped in the same ZIP, requiring only one call for textures, instead of 2. And the JPG wouldn't have to be converted back to BMP in order to work for most viewers (except Modeler, which is intelligent enough to read both formats, as well as zipped RWXs). --------------9EC022450E44EC105ED10231 Content-Type: text/html; charset=us-ascii Content-Transfer-Encoding: 7bit <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> JPGs are a lossy compression format.

Zipped BMPs do have the advantage of putting all required files into a single ZIP file. BMPs are really big once unzipped, but they would have the advantage of not needing decompression to use (after unzipping) like JPG, GIF, etc. This might make the browser run faster?

See http://www.cdrom.com/pub/png/ and particularly http://www.cdrom.com/pub/png/pngintro.html . PNG is not a replacement for JPEG, but it's better for images with sharp edges and/or few colors (especially text-based signs/logos/etc.). Zipped BMPs are in the same class as PNG, and support for them would be trivial to add to the browser since it basically already exists. PNG support would be nice but would also be more work, especially if Roland were to try to support full alpha-blending and gamma-correction; I'm sure he has higher priorities. -- Greg Roelofs n_e_w_t_(at)_p_o_b_o_x_(period)_c_o_m Newtware, PNG Group, Info-ZIP, Philips Multimedia Center, ... |
