f:object-contentheight(	`$info` as map(*),

Description

Returns the content height, for reasons of historical accident, in the contentdepth attribute. This function returns the height of an object as a length (see Section 5.2, “Lengths and units”), if it has one.

If $image-ignore-scaling is true, or no contentdepth is specified for the object, the empty sequence is returned.
