|

<p>It is possible to change the text via
|
||||
<code>TextRun.setText(String)</code>. However, if the length of
|
||||
the text is changed, things will break because PowerPoint has
|
||||
internal file references in byte offsets. We currently update all
|
||||
of these byte references that we know about when writing out, but
|

there are a few more still to be found.

<code>RichTextRun.setText(String)</code>. It is not yet possible
|
||||
to add additional TextRuns or RichTextRuns.</p>
|
||||
<p>When calling <code>TextRun.setText(String)</code>, all
|
||||
the text will end up with the same formatting. When calling
|
||||
<code>RichTextRun.setText(String)</code>, the text will retain
|
||||
the old formatting of that <code>RichTextRun</code>.

<p>You may add new slides by calling

<code>SlideShow.createSlide()</code>, which will add a new slide

to the end of the SlideShow. It is not currently possible to

adding Escher objects to new slides is supported).
