SmartArt support / replaceText

[singerla]

          @singerla I'm working on a task which replaces the text present in the pptx of a particular slide. Also all functionality has been implemented in python using python-pptx lib. But I'm struggle at replacing text present in SmartArt, Charts etc. Does this pptx-automizer supports modifying SmartArt, Charts etc?

Hi @HarshalSangme,

I was playing around with SmartArt, and I'm sorry, but it introduces a whole lot of relations.

To get replaceText working on a SmartArt, we should introduce a new shape type and apply modifiers to e.g. ppt/diagrams/data1.xml. This is where PowerPoint stores the data for each SmartArt shape.

This is a very interesting feature and I think it could be useful for some other users to be able to modify SmartArt.

@MP70, isn't this similar to OLE?

@singerla similar I suppose in XML structure although obviously OLE is using the embeddings folder.

OLE support was quite light to be honest, I really handled it as a one off case from memory.

The commit 728cf3c brings basic SmartArt support.
