=Handling Microsoft PowerPoint (file format)=

This page discusses various available options for working with [http://en.wikipedia.org/wiki/Microsoft_PowerPoint#File_formats Microsoft PowerPoint] ''[en.wikipedia.org]'' documents in your Qt application. Please also read the general considerations outlined on the [[Handling Document Formats]] page.

One needs to distinguish between two different formats (this page deals with both of them):

{| class="infotable line" style="width: 95%; margin-left: 2.5%"
|
! Legacy “PowerPoint Presentation” format
! “Office Open <span class="caps">XML</span> Presentation” format
|-
| ''classification:''
| binary
| <span class="caps">XML</span>-based
|-
| ''main filename extension:''
| <span style="font: 1em monospace">.ppt</span>
| <font face="monospace">.pptx</font>
|-
| ''main internet media type:''
| <span style="font: 0.9em monospace">application/vnd.ms-powerpoint</span>
| <span style="font: 0.9em monospace">application/vnd.openxmlformats-officedocument.presentationml.presentation</span>
|-
| ''native format of PowerPoint:''
| until PowerPoint 2003
| since PowerPoint 2007
|}

==Reading / Writing==

===Using PowerPoint itself===

If you are exclusively targeting the Windows platform and Microsoft PowerPoint will be installed on all target machines, then you can use [http://doc.qt.io/qt-4.8/activeqt.html Qt’s ActiveX framework] ''[qt.io]'' to access PowerPoint’s .ppt and .pptx processing functionality through <span class="caps">OLE</span> automation. For an introductory code example (and a way to list the <span class="caps">API</span> provided by the PowerPoint <span class="caps">COM</span> object), consult [[Using ActiveX Object in QT|this how to]] ''[qt.io]'' (focuses on Microsoft Excel, but it works the same way for PowerPoint).

{| class="infotable line" style="width: 95%; margin-left: 2.5%"

! <span class="caps">COM</span> object name

===Using independent parser/writer libraries===

===Using manual <span class="caps">XML</span> processing===

Files using the <span class="caps">XML</span>-based (.pptx) format could be processed using Qt’s <span class="caps">XML</span> handling classes (see [[Handling Document Formats]]).

===Using batch conversion tools===

==Rendering==

===Using PowerPoint itself===

''<font size="0.9em"><font color="#530"><span class="caps">TODO</span>: If you know whether PowerPoint’s <span class="caps">COM</span> object (see above) supports rendering individual pages from a .ppt/.pptx presentation to images (e.g. for thumbnails), please edit this section.</font></font>''

…

==Interactive Viewing==

===Using PowerPoint itself===

''<font size="0.9em"><font color="#530"><span class="caps">TODO</span>: If you know whether PowerPoint provides a “viewer” ActiveX control that can be embedded in a Qt application through ActiveQT, please fill out this section (include links to relevant resources!)</font></font>''
