Hi All,

I am using TIFF library version 3.8.2 and I am facing problem opening certain scanned tiff files.

I am using TIFFClientOpen() function to read tiff files. For a test tiff file, I get a warning message

incorrect count for field "ExtraSamples" (0, expecting 1); tag ignored. and then the above call to TIFFClientOpen() returns NULL.

I looked at tiff sources and the warning is thrown from CheckDirCount() function in tif_dirread.c() function. Since the above message indicates a warning on debugging I saw that it will always fail in above case.

Is this a known issue? Is it due to the file being corrupt value for tag?

thanks in advance
-Krishna
