Hello,
and welcome to the list!
First, thanks for helping and doing all that. I can point you to some stuff
that might help you.
1 - look at debug.tcl, it has some usefull profiling and memory stuff
2 - the code you shown below is useless because the way animated images are
handled is completely different. Each anigif has a CxImage
associated with it which itself contains multiple CxImage objects representing
each of the frames of the anigif. With your code below, you'll
only get the image data stored inside of Tk's Image structure, not the memory
used by CxImage in the background.
3 - Most of the plugins will not affect the memory at all, apart from chameleon
plugin, that's because it uses an extension that adds a whole
themeing engine, so it's normal, and yes, chameleon uses a HUGE amount of
memory, all other plugins use none...
4 - what you found about the anigif taking 8MB is interesting.. I'd like to see
mor eprofilign done on this..
5 - look at the 'prof' package for tcl, it's a useful profiler, it could help
you.
Thx for all!
