I have a problem with some PDB-files, which are 'Tagged PDFs', created with Adobe Reader for Palm OS. Those I cannot convert to any other format. Does somebody know/has an idea how I can extract the PDF (or just the text!) from the PDB again (then to convert into a common format)? Having a rather large library of those 'PDF-PDBs', so being unable to import/convert them is quite problematic. I want to get away from the PDF-format to a common, open ebook-format and reader, but this currently stops for me the proceeding. Any assistance is greatly appreciated.
