Above versus below: Object not on top of any other object
The property "Object not on top of other object(s)" detects whether an object does not have other object belows it that it visibly overlaps.
The configuration options for a check based on the "Object not on top of other object(s)" property can be seen below.
The "Consider" option defines the set of objects for which it shall be determined which of these objects do not visibly overlap any other object from the set of objects defined by "Check against".
The example and exercise below make use of the check Text object not on top of other objects.kfpx and the PDF file Yummy Pumpkin Yoghurt.pdf which are available for download:
Running the check Text object not on top of other object(s) detects all text objects that do not visibly overlap any other object below them. As a consequence, this check will find all text objects "have nothing below them", as can be seen in the screenshot below: in the example, when the text "Squashes your hunger instantly" will be painted, nothing will have been painted in that text area before.
In order to find text objects that do visibly overlap other objects, see the article Above versus below: Object on top of other object(s).
