All in MiniExifTool

I wanted to list all the EXIF data for a photo. Is there a method for
that? Equivalent to ExifTool:

exiftool -h filepath

Thanks

You should better ask this at rubyforge:
http://rubyforge.org/tracker/?group_id=2912

You can use the method tags, which returns an array of all tags of the
file.

Here a simple example (no HTML output but this shouldn’t be difficult to
adapt):

require ‘mini_exiftool’

photo = MiniExiftool.new ‘file.jpg’

photo.tags.sort.each do |tag|
puts tag + ': ’ + photo[tag]
end

Have a look at the API-documentation
http://miniexiftool.rubyforge.org/
and the turorial
http://miniexiftool.rubyforge.org/files/Tutorial.html

Best regards

Forgot to add that this method is better than the exiftool -h, because
it gives the literal method name. I was having trouble guessing at some
of them. For example to get “Camera Model Name” is “photo.model.”

Thanks, that worked. I changed one line to

puts “#{tag}: #{photo[tag]}”

since it errored to begin with. Maybe a copying error.

I had looked at the docs but I didn’t know what to look for (still
don’t). I’m not confortable enough with Ruby nomenclature to be able to
figure out I need a method tags and I don’t see where’d I’d find that in
the docs and know what it would do.

Thanks

Sorry, my mistake.

You are learning. :slight_smile:
So my mistake above has maybe a teaching effect. :wink:
