Dear Oliver,

Thanks for your interesting answer.

• Where did you get your libtiff?
o I use the libtiff from http://bigtiff.org.

•       Try printing sizeof(uint64) to make sure it really is 8. 
o       I try to use sizeof(uint64) in this way, but it doesn’t resolve the 

problem.

BYTE* buffer_strip=(BYTE *)(_TIFFmalloc((altezzatile)*image_tiff_width*sizeof (uint64)));//ptr strip

• If you built libtiff yourself, make sure you used tif_win32.c and not
tif_unix.c.
o I’m sure to use tif_win32.c

•       Does it work if you use no compression instead of jpeg? 
o       Yes, If I use COMPRESSION_NONE it works, but there’s the same problem: when 

I open the output’s image, there is an error message: “invalid or unsupported tif file”

• Does it really break only when you reach 4GB file size, meaning it works with a BigTIFF smaller than that?

o Yes, It works with TIFF smaller 4GB and the output’s image is correct, but if the uncompressed image is over 4GB I can’t open my output image.

Hi,

I’m italian and excuse me for my elementary english.
I’m C++ programmer and I’m built a code to create BIGTIFF.
I use Visual Studio Express 2012.

I installed the libtiff-4.1, but I’ve some problem to setting the bigtiff over 4GB, in fact the output image done an error when I try to open:

Can you help me, please?
