Looking at the changelog, there are also a number of bugfixes, portability fixes, better PNG support, etc. I was not suggesting that rrdtool use JPEG. > 3.) the version of gd used in rrdtool has been modified to NOT contain any > unisys compression code at all not even the image decoding code contained in > the original 1.3 version.

And so you should. This modification is noted in the appropriate places in the Debian package, so this should not be a problem. I have gotten no complaints as yet. I don't see the point of ripping JPEG support out of libgd. The reason I link rrdtool the way I do is that Debian contains a package for the gd library, version 1.8.4, as well as libpng and zlib. It would be inappropriate to link rrdtool with a different version of this library than the one used by the rest of the system. Actually, I have noticed that the old libgd package (with GIF) support has been resurrected in a new package in Debian (with a different library name) to support programs like rrdtool which require the GIF version of the library. I intend to link the next upload of rrdtool against this library, and restore GIF support and compatibility with vanilla rrdtool. -- - mdz -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-developers WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
