I hope this is my last annoncement (I begin to feel like a spammer). I've incremented the version numbers of both libraries. It was necessary to make some correction in the text files to comply with the IJG licencing. If you donloaded the previous version please discard it and download the new version.
(The old links are still working but they just gives you a small zip file containing the new links) jcpalm 1.0 is a Jpeg Compression shared library for Palm OS based on the IJG code. It was ported to Palm OS by IDEO, TRG & Harold Howe in 2000 I made some minor corrections in it and, with the permission of Harold Howe, I rebuild it to jcpalm 1.2 The new version can be downloaded from our web site. jcpalm 1.2 Jpeg Compression shared library for Palm OS (source and code): http://www.laubrass.com/doc/PUB/JPEG/jcpalm_lib_1.2.zip Harold Howe's original version of jcpalm can be downloaded from the eyemodule web site: http://www.eyemodule.com/developer/index.asp jdpalm 1.1 is a Jpeg Decompression shared library for Palm OS also based on the IJG code. Harold Howe started to port it to Palm OS but never finished it. With his permission, I have completed the porting. It can also be downloaded from our web site. jdpalm 1.1 Jpeg Decompression shared library for Palm OS (source and code): http://www.laubrass.com/doc/PUB/JPEG/jdpalm_lib_1.1.zip You can use those libraries freely provided that you follow the licencing terms. See jcpalm.txt and jdpalm.txt The bigger difference with jcpalm implementation is that you can compress the image as you get it from the image source (zire 71 camera in my case). You just feed the data line by line to the compressor. That way you don't have to store the full uncompressed image (about 1 meg for a 640x480 picture). A callback gives you the compressed image by chucks of around 16K. It is the same principle for the decompression phase(jdpalm). A callback gives you the decompressed image by chucks of around 16K. You can display it, store it or transmit it as you receive the decompressed image without having to store the full decompressed image. Anyway, if you like it, use it. If you don't... well don't use it. I hope you will like it :) If you find any bug or error, please let me know so that I can make changes and update the library. I would also appreciate your comments. Note: As stated in the license, it is an "AS IS" library. Laubrass and I do not offer any support nor guarantees. Usage is at your own risk and responsability.
