The PDF Parts module enables a teacher to provide a set of freely selected pages from a PDF file as a course resource.

1. Add a new PDFParts to a course.
2. Configure all of the standard settings: name, description etc.
3. Select PDF file setting - upload a PDF file.
4. Display setting - choose the display type (currently, only Force download and Open are implemented).
5. Pages setting - it is similar to the setting from any Print dialog that allows you to select a page or page ranges for printing. The values must be set in a format like 2-4,7,8,10-12.

Now when a student clicks on this resource link he gets only the pages specified in Pages setting.

The Teacher can add only one PDFParts instance to a course and set it to dynamically choosing of page ranges. The module accepts an optional GET parameter called "pages" which will override the corresponding base setting.

Suppose the Teacher added a PDFParts module to course with the id: 4720. Then he can build links in this format:

    http://<MOODLE_SERVER>/mod/pdfparts/view.php?id=4720&pages=2,4
    http://<MOODLE_SERVER>/mod/pdfparts/view.php?id=4720&pages=2-4,7,8,10-12

in order to provide the students with the precise pages where the needed information resides, for example the page with the solution to an exercise, or a page with the definition of a term.

• If the Pages setting is empty then the whole document is served to user.
• The Open display type may not work in all browser.
• Not all PDF files of version higher than 1.4 are processed without errors.

The PDFParts module was created based on an idea that came to me after seeing the PDF Page Limiter (mod_pdfpager) module by Geoff Eggins.

• The extracted pages are generated on demand; more efficient is to generate once and store the result in the server file cache; then serve to users the file from the cache.
• Add support for PDFtk (http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/)
