Wrong resolution value

[slein]

Hello,

we are using ImageMagick (6.4.8 Q16, Windows) to identify the resolution of an image.

Now we discovered a problem with some JPEG images:

Code: Select all

Format: JPEG (Joint Photographic Experts Group JFIF format)
Class: DirectClass
Geometry: 5158x3434+0+0
Resolution: 0.0305x0.0305
Print size: 169115x112590
Units: PixelsPerInch
...

As you can see the resolution as well as the print size is completely implausible. According to PhotoShop or Gimp it should have a resolution of 305 dpi.
Do you have any idea how to get the correct resolution value?

Thank you!
