Commented Unassigned: Coder Error Reading TIFF Image with Group 4 Compression [1113]

Reading TIFF CCITT Group 4 (scanned or faxed) images with MagickImage in C# throws MagickCoderErrorException. The exception message is shown below:
Magick:: Null count for "Tag 32934" (type 4, writecount -3, passcount 1).
'_TIFFVSetField' @ error/tiff.c/TIFFErrors/563

If the TIFF image is decompressed first, then the reading works fine. Anyone came across this error before and any suggestions on how to resolve this?

Thanks,
Sam

Thanks for the prompt reply. I am using the Magick.Net Q16 x64 net40-cleint. File version 6.8.7.101.

Since there were other posting on the error “Unknown field with tag 32934 (0x80a6) ", I believe it was a proprietary metadata added by some image processing apps.

Should these be treated as warning instead of errors? Another member in my team tried converting the badImage.jif with pure ImageMagick and got similar error, but the output was a valid jpg.

$ convert badImage.tif convertedImage.jpg

convert: Unknown field with tag 32934 (0x80a6) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/842.
convert: I2e0f0220022311de82febb7dd5c17f30.tif: Null count for "Tag 32934" (type 4, writecount -3, passcount 1). `_TIFFVSetField' @ error/tiff.c/TIFFErrors/561.
