Informations about the package focus

The plugin does two things:
- It provides a custom field that allows you to set a focus point. The focus point is saved to the meta data file.
- It provides a new method
focusCrop(), which uses the focus point saved in the meta data file to crop an image in such a way that the focus point is in the center of the cropped image – or (if that's not possible) at least isn't cropped.
⚙️ Requirements
- Kirby CMS, Version 3.6
- GD Library or ImageMagick
Please check out the kirby-3.5 branch, if you are using Kirby 3.5 or a version even older than that.
