I run into situations when I get customer PDFs that need to be edited. When they load in Acrobat Reader it works fine. However if I load it into Illustrator it asks me to point it to the linked file. The question is how does Acrobat Reader open a PDF file and show a linked file when it is not embedded? Why can't Illustrator do the same thing?
This is more of a technical question, but any information would be helpful. Thanks.
For linked images, your PDF file contains a thumbnail image along with the reference or address of the actual image. Reader will display this thumbnail. Now, wanting to edit the PDF in Illustrator, it wants to enable you working on the actual image. Hence it asks you to point to the linked file.
