Pageviewer

For collections that have page images, PB tags are inserted into the SGML with various attributes: image file name, page sequence number, book page number, feature (type of page), image format, etc. This information allows pageviewer to navigate the pages, which are displayed as GIFs or PDFs.

• Data
  • page images are stored as TIFF, but delivered as GIF and PDF
  • tools: tif2gif for GIF converstion and psprint and distiller (changing over to c42pdf) for PDF
  • pageview.dat: each SGML document has a pageview.dat file created containing all the page information from the PB tags (example pageview.dat file and sgml file from which it is created) (also see encoding workshop for information on creation of this file)
