MS Office Forum / General PowerPoint Questions / February 2007extracting images from placeholder objs
Hi, I'm using the C# API to extract images and text from PowerPoint slides. I have no problems extracting text and pictures when they are the msoPicture type. However, when pictures are within the Placeholder I don't know how to determine that the ppPlaceholderObject contains a picture, and assuming that it does and attempting to export it doesn't work. I'm pretty new to the PowerPoint Object Model and its API so any help is appreciated. Thanks! > Hi, > [quoted text clipped - 4 lines] > it does and attempting to export it doesn't work.

If not, delete it. ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ Thanks for your response, Steve. I'm not sure that I follow how to just "copy the picture". Wouldn't copying the shape just make a copy of a placeholderformat shape of type ppPlaceholderObject? How do you copy the picture if you don't even know it's a picture? The ppPlaceholderObject could also be a diagram, chart, table, media clip, etc. Moreover, I don't know how to access the shape within the placeholder shape. I'd appreciate any clarification to this. Thanks!

No, because you can't create your own placeholders in PPT, nor can there be more than one placeholder of a given type on a slide, so when you copy the placeholder, PPT converts it to a normal shape (of the type contained in the original placeholder). > How do you copy the picture if you don't even know it's a picture?The > ppPlaceholderObject could also be a diagram, chart, table, media clip, etc. You copy first, then test to see what the .Type of the new shape is. If it's something you want to work with, you're off to the races. If not, you delete it. Make more sense? > Moreover, I don't know how to access the shape within the placeholder shape. > I'd appreciate any clarification to this. There's no shape within the placeholder shape. It *IS* a placeholder shape, but one that happens to contain other content. > Thanks! > Melanie [quoted text clipped - 17 lines] > > PPTools: www.pptools.com > > ================================================ ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ Thanks a lot, Steve!
