Nico,

I downloaded the llb and tiff for windows from http://gnuwin32.sourceforge.net/packages/tiff.htmt. I got the following error message when I tried to run libtiff_example2.vi.

Error 1097 occurred at Call Library Function Node in libtiff2_writeScanLine_U8.vi

Possible reason(s):

LabVIEW:  An exception occurred within the external code called by a Call Library Function Node. The exception might have corrupted the LabVIEW memory. Save any work to a new location and restart LabVIEW.

Do you have any idea how I can solve the problem? Thanks.

Mmm... could you tell where is the error generated in "libtiff2_writeScanLine_U8.vi"? All the "status" numeric outputs ("status_width", status_length" etc.) should be "1".

Do you get the same error by selecting "U16 ScanLine single page"? What about choosing a different tiff format ("U8 striped single page")?

The error is generated in call function TIFFSetField( ). The error persisted when I selected "U16 ScanLine single page" or "U8 striped single page". I have no problem to run example 1.

That's strange: could you please tell me which instance of TiffSetField() fails? There are many nodes calling TiffSetField() setting different tags (e. g. the first one to be called in "libtiff2_writeScanLine_U8.vi" set the tag 256, corresponding to ImageWidth).

Do you get the same error by choosing a multipaged file (choosing "U8 ScanLine multi page" in "libtiff_example2.vi")?

Anyone else having the same problem?

N,

It is the first TiffSetField function with tag 256 caused the problem. It might relates with the version of the Tiff library. I downloaded the latest version 3.8.2. Which verison are you using?
