I have several tiff image files which I need to convert to pdf files. Some of the files get converted successfully and I'm able to get the expected output while some of the files are having the above error while I try to convert them and I get the output file as a complete black image. I'm trying to do the above task using Imagemagick.
I tried to find more about this problem on the internet. What I understood is that the problem is with the T6Options tag of the tiff file, which is (none) in my case. I'm not able to convert this file to any compression, I tried tiffcp, exiftool, tifftopdf but nothing works
Below is the information regarding the file, which I got using exiftool:
