◆ _ungroup_compensate_source_transform()

static void _ungroup_compensate_source_transform	(	SPItem *	item,
		SPItem const *const	expected_source,
		Geom::Affine const &	source_transform
	)

static

Helper function for ungrouping.

Compensates the transform of linked items (clones, linked offset, text-on-path, text with shape-inside) who's source is a direct child of the group being ungrouped (or will be moved to a different group or layer).

Parameters

item	An object which may be linked to `expected_source`
expected_source	An object who's transform attribute (but not its i2doc transform) will change (later) due to moving to a different group
source_transform	A transform which will be applied to `expected_source` (later) and needs to be compensated in its linked items

Postcondition: item and its representation are updated
