From 3c5f6a7f81c5882de6bcd0afcc528e8643d95f35 Mon Sep 17 00:00:00 2001 From: Miklos Vajna <vmiklos@collabora.com> Date: Wed, 10 Jun 2020 11:07:43 +0200 Subject: [PATCH] PPTX import: handle adjust values from both the shape and its placeholder The direct problem is a crash in CustomShapeProperties::pushToPropSet(), the code just hoped that the input file doesn't have more adjust values than the # of adjust values we allocate based on the preset type. Fix the crash, but there is a deeper problem here... The shape can inherit custom shape properties from a placeholder, then later it can have its own custom shape properties. When it comes to adjust values specifically, we used to just append own adjust values to the end of the list. This way we got the double of expected adjust values. And later rendering took the N expected adjust values from the start of the 2N element list, so we used the adjust values of the placeholder, not of the actual shape. Fix this by clearing the custom shape geometry once we know we have our own preset geometry.
