Bogoss,

Please mail plain text messages only to mailing lists.

I try to use libtiff library with a Console Win32 Project and I’ve a problem to close an existing TIFF file.

I just do:

In = TIFFOpen(“temp.tif”,”r”);

TIFFClose(in);

I’ve an error on TIFFClose: First-Chance exception in test.exe

> (NTDLL.DLL): 0x0000008: Invalid Handle

Chances are this is because you've never received a proper TIFF* in the first place as a return of TIFFOpen, because the "temp.tif" wasn't found. Add an error check, like this.

TIFF *in;
In = TIFFOpen(“temp.tif”,”r”);
if (In==NULL)
  /* some error occured */
  ...
else
  TIFFClose(in);

Probably things work better if you pass a full filename with complete path.

For more information on TIFFOpen, including error return value, see http://www.remotesensing.org/libtiff/man/TIFFOpen.3tiff.html.
