+When the [crop](#crop) info option is used with the `obj`/`objw` gravity type, the `objects_position` option allows you to adjust the position of the detected objects on the crop area.

+This option takes the same arguments as the [objects_position](./processing.mdx#objects-position) processiong option.

+If you need to get info about the objects position in the original image, you should use the [detect_objects](#detect-objects) info option.

 * `gravity:objw:%class_name1:%class_weight1:%class_name2:%class_weight2:...:%class_nameN:%class_weightN`: ((pro)) object-oriented gravity with weights. The same as `gravity:obj` but with custom weights for each class. You can use the `all` pseudo-class to set the weight for all the detected objects. For example, `gravity:objw:all:2:face:3` will set the weight of all the detected objects to `2` and the weight of the detected faces to `3`. The default weight is `1`.
 * `gravity:fp:%x:%y`: the gravity focus point. `x` and `y` are floating point numbers between 0 and 1 that define the coordinates of the center of the resulting image. Treat 0 and 1 as right/left for `x` and top/bottom for `y`.

+* `type` - specifies the position type. Available values:
+  * `no`: north (top edge)
+  * `so`: south (bottom edge)
+  * `ea`: east (right edge)
+  * `we`: west (left edge)
+  * `noea`: north-east (top-right corner)
+  * `nowe`: north-west (top-left corner)
+  * `soea`: south-east (bottom-right corner)
+  * `sowe`: south-west (bottom-left corner)
+  * `ce`: center
+* `x_offset`, `y_offset` - (optional) specifies the position offset along the X and Y axes.

+**Special positions**:
+
+* `objects_position:fp:%x:%y`: the focus point position. `x` and `y` are floating point numbers between 0 and 1 that define the coordinates of the center of the objects' area in the resulting image. Treat 0 and 1 as right/left for `x` and top/bottom for `y`.
+* `objects_position:prop`: the proportional position. imgproxy will try to set object offsets in the resulting image proportional to their offsets in the original image. This position type allows the picture scene to be maintained after cropping.
