Dear Gavin and Herbert,
Thank you so much for making these VIs available. I was looking for some time for a replacement for a libtiff LabVIEW library that only ran on 32-bit LabVIEW. Your reader is by far the fastest that I have found loading a 11MB U16 TIFF file in 133ms. What makes it special is that it runs both with 32-bit and 64-bit LabVIEW. After some minor optimization, your VI loads the file in 74ms (!). I have renamed the modified reader into TIFF File Reader (LAVA.org).vi.
Note also, that I have crosslinked this thread with a discussion on the LabVIEW discussion board, http://forums.ni.com/t5/LabVIEW/Labview-libtiff-implementation/td-p/929843/highlight/false/page/7. I hope you don't mind. I attach an updated copy of the library to this message (LabVIEW 2011).
Thank you again for your work.
Best regards,
Peter
