Description:
thumborpiliptcengine 7.4.7.4
thumbor-piliptc-engine
thumbor-piliptc-engine is a patched version from the legacy Pil imaging engine for thumbor.
Warning : Since Thumbor release 7.5.0 , "piliptc" feature is integrated to official thumbor : this project will no more be maintained.
IPTC tags :
JPEG IPTC (International Press Telecommunications Council) tags are a set of metadata that can be embedded into JPEG image files to provide information about the image content, including ownership and copyright information. These tags can be used by photographers, artists, and publishers to identify their work and protect their intellectual property rights. By including IPTC tags in their JPEG images, creators can ensure that their ownership and copyright information is attached to their work and remains with it as it is shared and distributed across the internet. This can be particularly important for photographers and other creators who rely on their work to generate income, as it can help deter unauthorized use and ensure that they are properly credited for their work. In this way, JPEG IPTC tags can play an essential role in protecting the intellectual property of creators and maintaining the integrity of their work.
In Europe, image copyright is protected by various laws and regulations, such as the Berne Convention for the Protection of Literary and Artistic Works and the Directive on the harmonization of certain aspects of copyright and related rights in the information society. These laws provide creators with exclusive rights over their works, including photographs and images, and require that any use of these works by others be authorized or licensed by the creator.
The use of JPEG IPTC tags can be particularly helpful in enforcing these copyright laws. In fact, some countries in Europe, such as France and Germany, have enacted specific laws that require the use of IPTC tags on certain types of images, such as those used in advertising and editorial content. These laws require that the copyright owner's name and contact information be included in the IPTC tags, making it easier for potential infringers to identify and contact the owner for permission to use the image.
Thumbor :
this project is related with this issue : Preserve IPTC metadata #1301
kkopachev This is not possible now with default Pillow engine, as Pillow itself does not have a way to save IPTC/XMP data.
scorphus You can try and use thumbor-wand-engine, which is a new engine built on top of ImageMagick with support to IPTC/XMP data.
So we must choose between legacy engine 'thumbor.engines.pil' (Pillow) or 'thumbor_wand_engine' (imagemagick) if you want to preserve original image IPTC tags.
I tried the thumbor_wand_engine : it works fine ! it's maybe slower than "pil" but "thumbor" generated image contains iptc tags.
We need this feature for european/french laws compliance" about copyright.
I don't want to speak here about avantage/disavantage from each engine : speed, memory consumption, image rendering/quality ...
I wanted to stay on "pil" engine and provide IPTC preservation : so i start this small project.
In a near futur, i will try to "merge request" this feature on thumbor official project but it can be rejected because i add a new package dependance with iptcinfo3.
Releases:
v0.1.0 : pre-release : just a proof of concept : working version but not ready for production
v0.2.0 : remove iptcinfo3 package requirement : write my own iptc raw copy class to optimize usage within thumbor
v1.0.0 : add JpegIPTC package
v7.4.7 : new version modele
Try it !
