Automatic Gravity Crop

Chooses the most important image features and objects and sets the focal point on them when cropping.

gravity=smart

gravity=auto

gravity=face

gravity=meta

Smart gravity

Sets the crop focal point on the people in the image or on the most prominent featues if no faces are detected. Useful for creating thumbnails from images with different aspect ratios.

Examples

Preview	Syntax
	/docs/mountains.jpg?w=300
	/docs/mountains.jpg?h=300&w=300&gravity=smart
	/docs/hotel.jpg?h=300
	/docs/hotel.jpg?h=300&w=300&gravity=smart

Automatic gravity (legacy)

If you prefer to use the legacy automatic crop, just set gravity operation to auto.

Examples

Preview	Syntax
	/docs/boat.jpg?h=300
	/docs/boat.jpg?h=300&w=300&gravity=auto

Face gravity

When using gravity=face, all images with one dominant face are focused on this face upon cropping. If there are many or no faces in the image, gravity falls back to auto.

If you would like to try and include multiple faces in the image, you can use gravity=smart

Examples

Preview	Syntax
	/docs/classroom.jpg?h=300&w=300&gravity=face

Metadata gravity

When using gravity=meta, all images having a custom focus point defined in the library will use this as if using the focal point crop. If there is no focus point defined in the image metadata, gravity falls back to auto.

You can override the fallback by chaining the methods, so that in case there is no focus point defined in the library's image metadata, it would proceed using another method like face, trim, or other.

eg. of use: gravity=meta,face
