Convert unable to extract exif from tiff

I'm unable to extract exif from most tif files. When running commands like `convert image.tif output.exif` I get the error message:

Code: Select all

convert: no APP1 data is available `output.exif' @ error/meta.c/WriteMETAImage/2360.
identify is however able to extract exif values from the same image.

The an example of an image that causes the problem is here: http://wiki.sindri.info/images/image.tif

I'm using ImageMagick 6.6.2-6 2010-12-02 Q16 on Ubuntu 10.10

Try
  • identify -define tiff:exif=true -verbose image.tif
If that fails, try upgrading. We tried the command with ImageMagick 6.6.7-8 and ImageMagick read the TIFF EXIF profile.

I just tried `identify -define tiff:exif=true -verbose image.tif` and that resulted in a Segmentation fault.

Not that that command would help at all, what the command I am trying to run does is extract the binary data that stores the exif in the image, identify just produces formatted text output. Also in my original report I mentioned that identify is able to read the exif data (although I misspelled identify quite badly, I've fixed that, sorry).

It might be of interest that I'm running 64 bit Linux. I have the same problem on another box that has ImageMagick 6.6.5-6 2010-11-05 Q16 (also x86_64).

I'll try the latest IM version and if this is also an issue on x86_32 architecture later today.
