Thanks For Help Arshad 

I have the same problem of getting a white horizontal line through the center of images when open  PowerPoint 2007 to PDFCreator.  It looks like the image is processed in two halves and they don't quite line up in the middle.  I am using PDFCreator 1.2.1 on Windows 7 64 bit pro.
