Subject Re: Issue regarding PPT

Hi Sailaja,

Regarding 2). I'm doing the same indeed by scanning all text runs in all
text paragraphs. For tables, you indeed need to walk through all tables and
their cells, I guess.

Regarding 3). I'm doing something similar. But note that Powerpoint might
store a text in a text paragraph in several textruns. E.g. the text "Hello
world!" in one text paragraph, might be stored one, two, three or even more
textruns. You can simply call .setText on a text paragraph, but this will
clear all textruns and might mess up your text layout. The workaround I
created for this is to only call setText on the first textrun in the first
text paragraph with the appropriate text and call setText("") on all other
textruns in that text paragraph. An example can be found on
http://pastebin.com/Y7vFUcEN. It's Scala code, but you should be able to
map it to Java code.

Regarding 4). I'm not sure how to replace pictures, but you can simply
create new ones based on existing images on disk. See:
