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

exiftool supports PNG, and there are rubygems wrapping it:

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

ChunkyPNG supports this

img = ChunkyPNG::Image.from_file('image.png')
