From c22ab1cba13d59d7982d8972ece7e8a64e9a74fa Mon Sep 17 00:00:00 2001 From: Miklos Vajna Date: Fri, 11 Sep 2020 17:30:27 +0200 Subject: oox smartart: add support for syncing font heights of multiple shapes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When 2 or more shapes have their text set to autofit and they have a constraint like: Then make sure that the automatic font size is the same for all shapes and all content fits, by using the smallest scaling factor from all relevant shapes. Some rework is needed, because normally oox::drawingml::Shapes don't have access to their parents, at the same time there can be multiple SmartArts on a single slide, so storing the grouping info in the filter is problematic, too. Solve this by storing the grouping in the toplevel oox::drawingml::Shape and exposing them in XmlFilterBase just during the time the children of the toplevel shape of the SmartArt are added. This works, because we know SmartArts can't be nested.
