Batch Metadata updating with BIMP.

[YeboiXd]

Hello. I am very new to scripting and plug-ins in general. I am trying to create a script that works with BIMP (Batch processing of GIMP) that gets the metadata from each image and updates selected fields while keeping the non-updated ones. I mainly want to update the Copyright of each of the images that are batch processed. I know I can use exiftool for this, but I am also using BIMP for more than just editing metadata and would like to only use BIMP for all these purposes. I know I need to use pdb.gimp_image_get_metadata(image) and pdb.gimp_image_set_metadata(image,data). But I just don't know how to code the script to do what I want it to do.

Thank you in advance!

Code:

➤>import xml.etree.ElementTree as ET

➤># metadata as string
➤>metadata = pdb.gimp_image_get_metadata(image)

➤># Parse to XML Tree
➤>xmlTree=ET.fromstring(metadata)

➤># Find relevant item (the autho is the "Artist", the "Copyright" is actually
➤># the license name (for instance "CC-BY-SA")

➤># Brute force version
➤>authorItem=[item for item in xmlTree if 'Artist' in item.attrib['name']][0]

➤># Xpath version for the illuminati
➤>authorItem=xmlTree.findall("*[@name='Exif.Image.Artist']")

➤># Show what we got
➤> print authorItem.attrib['name'],'=',authorItem.text
Exif.Image.Artist = Ofnuts

➤># Update value
➤>authorItem.text='Someone Else'

➤># XML tree back to string
➤>metadataNew=ET.tostring(xmlTree)

➤># String back to image metadata
➤>pdb.gimp_image_set_metadata(image,metadataNew)

File ➤ Export as /tmp/ShowAuthor.jpg

Then in a terminal:

Code:

➤ exiftool /tmp/ShowAuthor.jpg | grep Artist
Artist                          : Someone Else

Great work! Will this work as a plug-in with BIMP? Also is the XML version of the Copyright tag just "Exif.Image.License"? If not where can I check those properties?

No, this is the core of a plugin, needs some boilerplate around it.

Got it! I will go ahead and try it.
