[graphics-dev] PowerPoint vs Impress Rendering Inquiry

[Joseph Armbruster]

I am interested in migrating a product from Microsoft Office to OpenOffice.  I am currently evaluating the performance limitations of OpenOffice Impress as opposed to Microsoft Power Point.  Do you know if there is an efficient method of rendering several thousand shapes to an Impress 'slide'? For example, render 10,000 com.sun.star.drawing.EllipseShapes.  I have written sample code to do this in java, however it gets bogged down in one statement, namely, when my com.sun.star.drawing.XShapes object is being populated via add (and the images begin rendering).

Here are two observations with questions.

1. When I render 10,000 EllipseShapes and minimize the main Impress window, the rendering time rapdily decreases. It takes about one minute and fifteen seconds on my machine. It would probably take an hour if I kept the window up watched it.
?- Is there a way to pause rendering in Impress and start it after all shapes have been generated? Otherwise stated, is there a method that can toggle "refreshing"?

2. As the images are rendering, I noticed that the time to "add" each additional EllipseShape to my xShapes object slightly increases as more and more images appear on the slide.
?- Are there any pipelines within OO that could possibly avoid whatever overhead is being incurred during this add process?

Any insight on the topic is greatly appreciated. If you would like a copy of the test code, send me an email.

Thank You in Advance for your time
