Is there any gem to read exif data from png images

Question

I am uploading png images from iphone. I would like to read the gps information from the image. I am using EXIF Reader(GitHub) but it works only for gif and tiff format.

Any solution to read Exif data from png images will be useful

Answer 1

exiftool supports PNG, and there are rubygems wrapping it:

• multi_exiftool
• mini_exiftool

I'm not sure what the difference between these two are, though.
