- 2005-06-23: Web page renewed :-). Add a hint for OpenOffice/StarOffice users.
- 2005-04-21: New logo came!
- 2005-01-26: JWebPresenter SS 1.3 released! See Release Note/Change Log.
JWebPresenter is a free (GPLed) distance presenting system. It presents via the Web (currently HTTP/FTP supported), and is bitmap-image based to avoid compatibility problems. See Features for detail. It is useful in distance learning, meeting, or conferencing. Currently a release, called SS (Simple Solution, but you may call it Stable Solution :-)), is available. In a developing version, Motion Compensation (MC) is being considered, which is hopful to further reduce the data amount (though is not as efficient as I thought :-().
- Bitmap image based presenting: Hence we have no compatibility problem related to character corruption, locale, font, ... You can (and you must) use an authoring tool (e.g., PowerPoint, OpenOffice, MagicPoint, etc) to create the slides, then export into images to be presented with JWebPresenter.
- Platform independent: Any system satisfying the requirements should be OK, including Linux PC, Windows PC, PDA Sharp Zaurus SL-C760 (JWebPresenter SS v1.0x).
- Simplicity: I believe simple thing should be done simply. JWebPresenter SS v1.2.1 package (tar.gz) is only 36KB, including source, pre-compiled binarary, document, sample, and a 18KB (uncompressed size) license called GPL!
- Protocol and Image format independent: All protocols and image formats supported by JRE (Java Runtime Enviroment) should be OK.
- Efficience: There is little overhead in JWebPresenter. See note 1.
- Server (presenter): a Web (currently HTTP and/or FTP) server, perl or UNIX shell
- Client (audience): a JRE (Java Runtime Environment) v1.4+, in particular, with Swing support.
Ahh, everyone likes demostration. The next link is for you! But please remember that there is NO presenter here! The slides will automatically change in 5 seconds until finish.
- 1.: One may wonder how much data amount the bitmap-image based presenting requires. That's a good question. My study on 55 randomly picked PowerPoint files (1404 slides) shows that, averagely it is less than 50KB per slide in the 1023x768 resolution (which is roughly 1.75 times of the original PowerPoint file). Thus there is little worry on the bandwidth since generally slide in presentation changes at a low speed.
- 2. : OpenOffice and StarOffice have an export-to-HTML function. To use them with JWebPresenter, (and if you are using bash,) just do "for((i=1;i<=N;i++)); do ln -s img`expr i - 1`.jpg slide-1-$i.jpg; done" at the command line, where N is the number of slides. If you choosed PNG format when exporting, change jpg to png.
