Information about ppt and pptx to image conversion

[Josep Benavent <jo...@gmail.com>]

Hi!

I'm new to list. I'm interested in the conversion of ppt to images. I have
tested the available code that implements the conversion between ppt to
images. I have noticed, as is written, some limitations in this process
(some complex shapes are not supported and the code exits with
"java.lang.NegativeArraySizeException"). This is still unsupported or exist
any solution to that fact?

I'm also interested in converting pptx files to images, but I still can't
find any working example; can anybody explain me how to do it?

Thank you for the attention,

Josep Benavent

At the moment POI HSLF supports only 20 built-in shapes out of 255 defined in the .ppt format. Shape outlines are 
defined in http://svn.apache.org/repos/asf/poi/trunk/src/scratchpad/src/org/apache/poi/hslf/model/AutoShapes.java

Outlines are described in terms of java.awt.GeneralPath, this approach  is more or less corresponds to how shapes are 
described in the specification.

AutoShapes.java is easily extendable, to add more shapes you are advised to read the Office Drawing Specification which 
is avaiable at http://www.microsoft.com/interop/docs/OfficeBinaryFormats.mspx and define more shape outlines.

Rendering of PPTX files is not yet supported. Implementation of the .pptx format is in our plans, but it won't be 
earlier than the end of 2009.
