2008.02.12 09:45 "LibTiff JBig and huge memory consumption", by Rob Eisink
Platform used: - Windows NT 2000 service pack 4 - Windows NT 2003 server with large memory support enabled (/3GB swith in boot.ini) I've build a small application that calls TIFFReadEncodedStrip for an opened JBIG file which is suppplied by the JBIG kit. The tiff library used is tiff-3.9.0beta. The file used is \jbig files\A_FAT070702000780C0289.tif The function fails because a malloc returns a null pointer, indication a lack of memory. I counted the memory which was allocated within the JBIGkit only and that was wore then 1,6 Gigabytes! After that I build the same app with large address support on Windows NT 2003 server to enable 3Gigabyte support for the max virtual address space instead of the standard 2 Gigabyte. This gave the same result however the the memory allocated within the JBIG kit was more then 2.6 Gigabyte. Should this work on a 32 Windows NT machine or I'm doing something wrong.
