Missing EXIF data in identify (IM 6.9.4-1)

[micpalmia]

In 6.9.4-1, calling

Code: Select all

identify -verbose imagename

does not return gps location (GPSLongitude, GPSLatitude) and some other properties (e.g. DateTimeOriginal). Under the Properties section, there is now an unknown property indicating a count - not sure if that matters.

We are currently using ImageMagick 6.9.2-1 to extract image properties from photos (exif data, gps location), and we would like to update as suggested to the latest version. Any way to fix this on our side? Any suggestions?

In ImageMagick 6.9.4-1

while in ImageMagick 6.9.2-1, for the exact same image, we get

with ImageMagick-6.9.3.9 (targeting same image) i get:

Code: Select all

We also got a bug report on github (https://github.com/ImageMagick/ImageMagick/issues/198) and we just pushed a patch to resolve this. This will be resolved in the next version of ImageMagick.
