I'm using pdflatex to generate a document from hundreds of single-page PDF images. (The images are originally in Postscript but I use Ghostscript to convert them to PDF prior to running pdflatex). The Postscript images are actually Matlab/Simulink block diagrams which have a structure and hierarchy..
I'd like to add references/hyperlinks to these block diagrams so the reader can navigate through the document by clicking part of the block diagrams.
I can analyse the postscript images and gather cords for each block. Using Ghostscript I can add hyperlinks to individual PDFs at these cords. What I don't know is how do individual PDF images then get merged in pdflatex to allow the references to be updated. What URI should I use when adding the hyperlink. Should I use a hypertarget (anchor) on the target page?
