janfri / mini_exiftool

This library is a wrapper for the Exiftool command-line application (https://exiftool.org) written by Phil Harvey. It provides the full power of Exiftool to Ruby: reading and writing of EXIF-data, IPTC-data and XMP-data. Branch master is for actual development and branch compatibility-version is for compatibility with Ruby 1.8 and exiftool versions prior 7.65.

Attach back the metadata to its original file #23

Closed shilpi230 closed 8 years ago

shilpi230 commented 9 years ago

I extracted the metadata in xmp format from some jpeg and raw images now i need to attach that in some different file. How can i do that? I am able to do the same thing with ICC format with png images but its not working with jpeg images.

janfri commented 9 years ago

How would you do this with the exiftool command-line application?

shilpi230 commented 9 years ago

Extract the icc color profile of original image and attach it with whatever file with same mime type again using icc profile.

janfri commented 9 years ago

I have not much time at the moment. Could you give me please an example of command line arguments for exiftool to do this?

shilpi230 commented 9 years ago

yeah sure or if you can tell me where can i edit the code. I can include it :)

janfri commented 9 years ago

No I don't mean mini_exiftool I mean the exiftool command-line application from Phil Harvey which uses mini_exiftool. I don't have the time to read all the documentation how to solve your requirements with exiftool.

shilpi230 commented 9 years ago

first i am checking whether image has icc profile embedded or not if it is not then extract it form exiftool -icc_profile -b -w icc filename then attach it to some other image with exiftool '-ICC_Profile<=%d%f.icc' same_filename

shilpi230 commented 9 years ago

With xmp format exiftool -Tagsfromfile filename out.xmp and then attach it back with this command exiftool -TagsFromFile out.mp '-xmp:all<all' filename

To reattach you could try this with mini_exiftool:

photo = MiniExiftool.new('filename')
photo.copy_tags_from('out.xmp', ['all'])

But mini_exiftool is not designed to do such things. Maybe we could implement this with https://github.com/janfri/multi_exiftool my newer approach of a wrapper for exiftool.

So if the code above doesn't work it would be the best at the moment to do it on a direct way

system "exiftool -icc_profile -b -w icc filename"
system "exiftool '-ICC_Profile<=%d%f.icc' same_filename"
# or
system "exiftool -Tagsfromfile filename out.xmp"
system "exiftool -TagsFromFile out.xmp '-xmp:all<all' filename"

But be aware, you are responsible of handling errors.

Okay sure i will try my best :)
