2006.01.16 11:02 "Re: Problem closing TFF file : First Chance exception", by <tub95@wanadoo.fr>
Good morning all,
The problem concerning the error on the instruction TIFFClose : First-Chance
exception in test.exe (NTDLL.DLL) : 0x0000008 : Invalid Handle is resolved.
To resolve the problem, I installed tiff version 3.8. I had the 3.7.4
But now, it's new problem that I did not have before (maybe i must create a
new topic :/)
I have a memory leak when i create several tiff files.
I made a simple test : I open, write and close several tiff files and i see
in the task manager of windows that the memory increases 4Kb for every new
files.

for(int i=0;i<=10000;i++){
sprintf(nom,"test_%d.001",i);

i don't know if it's a bug ...
PS : to update libtiff to the 3.8, i just replace :
- libtiff.lib in "C:\Program Files\Microsoft Visual Studio\VC98\Lib"
- tiffvers.h
tiff.h
tiffconf.h
tiffio.h
in "C:\Program Files\Microsoft Visual Studio\VC98\include"
- and add dll depedencies in System32 directory
Thanks for your help :)
