Sure. Take a look at the Microsoft Developer Network documentation/example
here on the Export Method as it applies to a Presentation Object:
http://msdn.microsoft.com/library/en...asp?frame=true
The reason I recommend the Export Method (over SaveAs) is that it allows you
to optionally set the pixel resolution of the output image. Otherwise, your
image is saved to 72 DPI (for PPT XP, 2K, etc) in the size of a slide (the
default slide size is 10" x 7.5" which makes the default output image
720x540 pixels). Be forewarned that setting different aspect ratios will
cause PowerPoint to scale your image without preserving the aspect ratio of
the slide. You might want to consider using the page setup property of a
presentation to determine the output size of your pixels. See the PageSetop
property documentation here:
