IMDisplayDoc function "Tag 32934" Null count error

[Ganesh_B]

Hi ImageMagick,

I am a developer. Our Customer complained that attached image 'FILLPAGE.tif' is not getting opened/converted with ImageMagick '6.9.1-2'. I also tried ImageMagick '7.0.7-21' binary install. Still I am not able to open the attached file. ImageMagick application was popping up below error and image of error is also attached.

IMDisplayDoc function [DoReadImage] reported an error.
imdisplay.exe : Null count for "Tag 32934" (type 4, writecount -3, passcount 1). '_TIFFVSetField error 645

I have questions as below and need a solution.

- "What is the reason this specific file is throwing with latest ImageMagick 7.0.7-21" also
- "Can this be resolved in next version of ImageMagick or Hotfix/Fixpack"
- "Can this file or similar files with same error(at opening) be fixed by modifying the file itself or correcting the source application of image"

>> No link to attach files, please send the procedure to attach Image file.

Regards,
Ganesh.

Windows Photo Viewer can read the file and show an image.

Gimp v2.8.10 can also successfully read the image.

With IM versions v6.9.5-3 and 7.0.3-5, I get a warning and an error:

Code: Select all

identify.exe: Unknown field with tag 32934 (0x80a6) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/896.
identify.exe: FILLPAGE.tif: Null count for "Tag 32934" (type 4, writecount -3, passcount 1). `_TIFFVSetField' @ error/tiff.c/TIFFErrors/562.

I suspect TIFFlib reports the error, and ImageMagick won't override that. I suspect there is a problem in whatever software created FILLPAGE.tif.

The program "tiffcp" reports the error, but still copies the image, without copying the problem:

Code: Select all

tiffcp FILLPAGE.tif tmp.tif

So a workaround is to first use tiffcp.

A developer may comment further.

The latest releases of ImageMagick 6.9.9-37 and 7.0.7-25 can read the image you posted. It does report a warning and an error but the conversion appears to be correct.
