[R] "transparent" background for PDF

[Francisco J. Zagmutt]

Hi Dennis

Out of curiosity, how did you import the pdf to Power Point?  I am running 
windows so it may be different (and completelly irrelevant to you!) but when 
I want to place a pdf image in a PPT slide I copy the file to the clipboard 
and then paste it in Power Point.  Then in Power Point you can right click 
on the image-> show picture toolbar and then use the tool "Set Transparent 
Color".  That will give you a transparent background but you may not get be 
the best quality, so in general I prefer to save the image as a bmp or some 
other format and then insert that into Power Point directly using the Insert 
menu in PPT.

I hope this helps


Francisco
