Missing exif tags from identify (6.6.9-7)
Posted: 2013-12-07T02:25:49-07:00
I'm having some issues where ImageMagick does not detect all EXIF data in some images.
First test is on a stock Ubuntu-12.04.3-LTS:
No EXIF tags are listed amongst the properties.
Now for another file on the same machine (I removed all Histogram data when writing this post):
The last image contains a lot of EXIF tags in the properties.
Now, if I run the commands again on a stock Ubuntu-13.10:
and (again, I removed the histogram stuff):
The two images in question are:
https://raw.github.com/christeredvartse ... otated.jpg
https://raw.github.com/christeredvartse ... f-logo.jpg
Is this a known issue in the 6.6.9-7 version, or is there something wrong with the exif data in the 640x160_rotated.jpg image? The reason I'm using 6.6.9-7 is that I run some automated tests on Travis-CI (https://travis-ci.org), and they use the regular imagemagick package on Ubuntu-12.04.
Btw, when using the exif tool on both machines (not in the imagemageick package), all exif information is listed, so it seems that the images are somewhat correctly tagged.
