2008.08.11 10:44 "Supporting images > 2gb", by Alexander Johnson
Hi, Im trying to support images between 2gb and 4 gb. I've seen some reference to this in previous posts but I'm still unsure how to enable these larger files. From what I can tell offset needs to be set to unsigned to enable this. Is there anything else I need to do? Is there a particular version of libtiff I need to use to do this? I looked at 3.8.2 and it doesnt seem to have any of the functions required to support the larger files eg fseek64. Older versions like 3.5.5 seem to only support these larger files for Unix by setting USE_64BIT_API to 1 in tiffconf.h. I tried to use the bigtiff version 4.0 to open the larger files and had no luck with that. Any suggestions? Kind Regards -- Alex
