I would like to know how to do the following in Powerpoint 2007

1) Import entire PDF Document into PowerPoint and then edit this in Powerpoint
2) Copy graophics or designs in a PDF document into Powerpoint and then edit these if necessary

Your assistance in this regard will be most appreciated

Read this article by Microsoft, It answers both of your questions I believe.
Click on where it says Can I import PDF content into a PowerPoint presentation?

This is the process that they give for inserting a .pdf into powerpoint.

To insert a PDF into a PowerPoint presentation, do the following:

1. Click the Insert tab.
2. In the Text group, click Object.
3. In the Insert Object dialog box, click Adobe Acrobat Document, and then click OK.
4. Browse to the .pdf file you want to insert, and then click Open.

Thanks for the reply, much appreciated
