The latest CVS solved the issue. It was indeed a read error.
I am running into a strange problem with the latest libtiff 4.0.0beta5. I'm using Aqsis (an open source Renderman-compliant renderer) to generate shadowmaps larger than 4Gb. I'm adding option "8" to the creation mode and the image are fine but two important tags are missing: TIFFTAG_PIXAR_MATRIX_WORLDTOSCREEN, TIFFTAG_PIXAR_MATRIX_WORLDTOCAMERA.
The fields are missing with libtiff 4.0.0beta5: http://aqsis.pastebin.com/wZ8jvqpS
Libtiff 4.0 beta 5 is dated 2009-11-04 to me. From the most ChangeLog we
have this entry:
2010-04-20 Olivier Paquet <email@example.com> * libtiff/tif_dirinfo.c: Use correct set_field_type for TIFFTAG_PIXAR_IMAGEFULLWIDTH, TIFFTAG_PIXAR_IMAGEFULLLENGTH, TIFFTAG_PIXAR_MATRIX_WORLDTOSCREEN and TIFFTAG_PIXAR_MATRIX_WORLDTOCAMERA. They were unreadable with TIFF_SETGET_UNDEFINED, a regression from 3.9.2. http://bugzilla.maptools.org/show_bug.cgi?id=2139
So I'd try again with CVS trunk.
