Configure DAM Plugin for Images

[gaurav6358]

I am looking to develop a custom DAM Plugin to modify image. Example is a feature to maintain image aspect ratio, and upload all images by default in 1700 X 1700 px and trim any extra part of image from right and bottom if required.

Below link mentions to update values.yaml, but I cannot locate this file in docker. Or any other option to add a DAM plugin.

Any help is appreciated to configure plugin. I have developed my custom code to rectify the image, but facing challenge to configure this with Digital Assets upload button.

1. Create a local file as dam.config.dam.extensibility_plugin_config.json and dam.config.dam.extensibility_rendition_config.json
2. Contents for these files are available in https://help.hcl-software.com/digital-experience/9.5/CF217/manage_content/digital_assets/configuration/dam_extensibility/configure_dam_extensibility/#configure-dam-extensibility
3. Try mounting using volumes to /etc/config path in dam container.
