Export to PDF with MetaData

Question

I have a script that exports each individual page to a pdf with each page having it's own metadata.
It works fine except for on small thing.
The keyword array looks like this in the final PDF.
; "Keyword1, Keyword2, Keyword3
How do I get rid of the semicolon and quotes?
Thanks!

You mean rendered on top of the image? That info is already embedded inside the image as metadata. To render metadata on top of your image, you can use the slideshow module, add a text overlay with your custom metadata and export to jpegs. You can do similar things inside the Print module but you cannot control the placement of the text.
