CropAround plugin

Provided a set of focus rectangles, will crop the image while preserving the specified areas.

Coordinates must be in the source image coordinates.

Requires mode=crop and width and height to be specified to activate.


  1. Reference ImageResizer.Plugins.Faces.dll
  2. Add <add name="CropAround" /> to the <plugins /> section.


  • c.focus=x1,y1,x2,y2
  • c.focus=x1,y1,x2,y2,x1,y2,x2,y2…..
  • c.zoom=true (Crop as closely as possible to rectangles)
  • c.zoom=false (Crop minimally to meet required aspect ratio)
  • c.finalmode=crop|pad|max|stretch|carve (If we can't meet the desired aspect ratio given our constraints, what do we do next?)

Special ability when installed alongside the Faces plugin

  • c.focus=faces - Performs on-the-fly face detection and uses those coordinates. Can be resource intensive, so disk caching is recommended.

This plugin (CropAround plugin) is part of the Elite Edition
