I am using the latest build of libtiff tiff-4.0.0alpha on Windows XP 32-bit.

I am performing a test where I write a BigTIFF file that I would like to be greater than 4 GB.

The file size will not go over 4 GB ( 4,194,258 Kbytes).

I use TIFFOpen with the "w8" parameter.

Strip size is one row.

I write scanlines one at a time using TIFFWriteScanLine and watch the file grow. It always stops at 4 GB.


Do you know which file IO layer you are using? tif_unix.c works on windows, but only up to 4GB (AFAIK). You really need to use tif_win32.c for big file support. I'm not absolutely sure what is the default.
