The area of interest (short AOI) is a rectangular area inside a source image that is of special interest. When it is set, the AOI cropping modes will always preserve the marked area.

The AOI can be embedded in the metadata of images as an IPTC record with the name "AOI" or it can be set as a request parameter.

To embed an AOI into an image, you can use exiftool with the config file that's included with Converjon:

# this will set an AOI of 800x600 pixels
# offset by 100 pixels in both direction from the top-left corner
exiftool -config <path-to-config> -AOI="100,100,800,600" <path-to-image>
