Core dump converting a TIFF image

Post by iznogoud »

Hello,

Currently writing a PHP software I got a core dump on '$image = new Imagick($fullFileName);' instruction.

I tried to directly use 'convert" on the same picture:
# convert image.tif image.jpg
Segmentation fault (core dumped)

This is a valid TIFF image (I'm able to open it using Paint, The Gimp, etc.).

How can I help find a fix for this bug?

Exiftool says: " ExifTool:Warning='Bad ExifIFD directory'"

IM identify says:

Code: Select all

aa.tif TIFF 3693x1946 3693x1946+0+0 8-bit sRGB 256c 7.213MB 0.016u 0:00.015
identify.exe: Sanity check on directory count failed, this is probably not a valid IFD offset. `TIFFFetchDirectory' @ error/tiff.c/TIFFErrors/561.
identify.exe: Failed to read custom directory at offset 7206312. `TIFFReadCustomDirectory' @ error/tiff.c/TIFFErrors/561.
A developer would need to take a look.

EDIT: My test above is with IM v6.8.9-5. I suspect this isn't an IM bug, but an error in the file. Some software tolerates some errors. IM is quite strict.

IM shouldn't dump core. Are you using an old version of IM?

I'm running a 6.7.7-10 2014-03-06 Q16 version (installed using apt-get on Ubuntu 14.04.1 LTS).

Am I right when I think that I should self-compile the latest version?

Yes, to avoid the core dump, I suggest you install the latest version.

OK, I'll try in a couple of weeks.

Thanks for the help,

I'm running into the same problem. I'm converting a multipage TIF file from color to grayscale with the following command:

Code: Select all

convert -colorspace Gray -density 300 -compress lzw -depth 8 "Z:\Source\4201334562-20120728-20130515.tif" "Z:\Output\4201334562-20120728-20130515.tif"
And I get the error:

Code: Select all

convert.exe: Unknown field with tag 37680 (0x9330) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/857.
convert.exe: Unknown field with tag 40094 (0x9c9e) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/857.

Any ideas?

First your syntax is not truly IM 6 style. The input tiff should be read first. see http://www.imagemagick.org/Usage/basics/#cmdline


Most of you text is warnings that the TIFF file has meta fields that IM does not support. Tiff allows users to add lots of private meta fields. To turn that off add -quiet to your command. Try

Code: Select all

convert -quiet "Z:\Source\4201334562-20120728-20130515.tif" -colorspace Gray -density 300 -compress lzw -depth 8 "Z:\Source\4201334562-20120728-20130515.tif" "Z:\Output\4201334562-20120728-20130515.tif"
