This extension allows a user to generate new layers with segments of an image, outlined by rectangles formed using horizontal and vertical guides.
Users can choose whether to include the image borders in the calculations. The default behaviour is to only extract image segments enclosed within guides. At least 4 guides (2 vertical, 2 horizontal) are needed in this case.
Users can also choose to ignore sections below or above certain thresholds e.g. sections that are less than 100 pixels wide or greater than 1000 pixels tall.
