Hi All,

While breaking multipage tiff file using convert command, I am getting following warning and tiff file is not getting splitted.

convert.exe: Unknown field with tag 326 (0x146) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/891.

Can anyone explain when this error comes and how to fix this issue or is it a bug?

Do you get any output as it is a warning not an error?
What is you command?
Do you have a file you can upload for testing?
What version of IM are you using?
What operating system/language are you using?

Hi Bonzo,
The files get split into single page tiff. I am using convert b.tif c%d.tif command for the same.
The version of IM is Version: ImageMagick 6.9.3-2 Q16 x64 2016-01-23
I am using Windows 7 for the same.

Now the issue is if I directly use LibTiff command "tiffsplit.exe b.tif c.tif" It gives me the same error as mentioned but the generated files are corrupt.

As Bonzo says, there are no errors in that list; only warnings. "-quiet" will suppress warnings.

Your input file may be corrupt. Can you post it to somewhere like dropbox.com and paste the URL here?
