Cannot open tiff-files greater than 2GB

[SilvioM]

I'm trying to open an large tiff-image in Pixinsight.
The file is 2.02GB and I got the error:

*** Error: TIFF: Seek error at scanline 12414, strip 4139
*** PCL Exception: PCL TIFF Format Support: Error reading TIFF file: Q:/!Out/2014-11-11 - AstropanoTF/pano0_zip.tif
Unable to read image: Q:/!Out/2014-11-11 - AstropanoTF/pano0_zip.tif
<* failed *>

The error seems similar to this bug dating back to 2011:
http://pixinsight.com/forum/index.php?topic=3381.0

Files under 2GB load fine. Photoshop opens the 2.02GB-Tiff without Problems.

I'm using Pixinsight 01.08.03.1115 Ripley (x64) under Windows 7 64bit. The filesystem is NTFS.


Hope you can help,

Silvio.

Hi Silvio,

Bug confirmed. This is a regression in the Windows versions of PixInsight, resulting from the update to a new version of LibTIFF. The FreeBSD, Linux and Mac OS X versions don't have this problem.

This is now fixed in the new version that we'll release tomorrow. Thank you for discovering this issue.

We have just released an update that fixes this bug for PixInsight 1.8.3.1115 on Windows. Sorry for the inconvenience, and thank you again for finding this problem.

Wow, that was quick!
And it worked.

Thank you very much for that really quick fix.

Silvio.
