Bug ID: 62736
Summary: [PATCH] Relations on XSLFPictureShape are removed
unconditionally
Product: POI
Version: 4.0.x-dev
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: XSLF
Assignee: dev@poi.apache.org
Reporter: bmate...@gmail.com
Target Milestone: ---
It is only safe to remove a relation of a PictureShape if there are no more
relations to that media on its slide.
I created a small example pptx where I copy pasted an image on a slide and
removed only one of them using poi. The current implementation removes the
relation and the document gets corrupted because of the invalid link.
The proposed fix is to iterate on the pictures of the slide and only remove the
relation if that is the only one.
