From 713493c107e6a210ef9b87d033efd0614271483a Mon Sep 17 00:00:00 2001 From: Miklos Vajna Date: Mon, 23 Jan 2023 20:10:30 +0100 Subject: tdf#150806 ODT export: fix fallback svg:width/height for zero layout size The reported problem was that once tracked changes is enabled and an image is deleted, its aspect ratio changes on save. What happens here is that the image's frame is marked as a redline deletion, so when the ODT export writes the file, it'll have a zero size. But this zero size is nothing we should take into account on save, XMLTextParagraphExport::addTextFrameAttributes() expected to always have a valid layout size if the LayoutSize property is available. Fix the problem by adding one more condition where we ignore the layout size, which was already there since commit 80550ade305b9e68c6281a258d162bc2c413713a (tdf#150990 ODT export: fix zero layout size of scale/scale images, 2022-09-20). Note that this way the written side will be the original one, so only the aspect ratio will be correct, but that was accepted as a compromise earlier.
