==PDF annotation assignment plugin==

The PDF assignment submission and feedback plugins allow a teacher to annotate and return PDF files that have been submitted by students. It is based on the previous [https://moodle.org/plugins/view.php?plugin=assignment_uploadpdf UploadPDF] assignment type by Davo Smith, updated to work with the Moodle 2.3+ 'assign' module (rather than the Moodle 2.0-2.2 'assignment' module).

Teachers can add and position comments and draw lines, ovals, stamps, rectangles and highlights onto the student's work, from within the browser, before returning the work to the student.

This plugin is available in Moodle 2.3+, Moodle 2.0-2.2 and Moodle 1.9 versions.

This is the Moodle 2.3+ version - you can download the Moodle 1.9 version from here: https://github.com/davosmith/moodle-uploadpdf/zipball/MOODLE_19_STABLE

and the Moodle 2.0-2.2 version here: https://github.com/davosmith/moodle-uploadpdf/zipball/master

'''THERE ARE A FEW IMPORTANT ITEMS TO NOTE IN THE INSTALLATION, PLEASE READ CAREFULLY'''

===Installation===

''Note - the [https://moodle.org/plugins/view.php?plugin=assignsubmission_pdf assignsubmission_pdf] plugin can, theoretically, be used without the [https://moodle.org/plugins/view.php?plugin=assignfeedback_pdf assignfeedback_pdf] plugin. On its own, however, it has little advantage over the standard 'file' submission plugin (other than coversheet handling). The assignfeedback_pdf will not do anything on its own (and cannot be installed without the submission plugin).''

# Download and install GhostScript ( http://pages.cs.wisc.edu/~ghost ) - or install from standard respositories, if using Linux.
# Under Windows, do not install to a path with a space in it - that means you should install to something like 'c:\gs' NOT 'c:\Program Files\gs' (note you only need the files 'gswin32c.exe' and the dll file from the 'bin' folder, all other files are unnecessary for this to work).
# Unzip the submission pdf and feedback pdf plugin files to folders on your local machine
# Upload the plugin files to <siteroot>/mod/assign/submission/pdf and <siteroot>/mod/assign/feedback/pdf
# Log in to Moodle as administrator, then click on 'Home'.
# Visit 'Site admin > Plugins > Assignment plugins > Submission Plugins > PDF Submission'. Adjust the 'Ghostscript path' to where ghostscript is installed (should not need changing on a Linux install).
# All being well, you should now be able to add submission and feedback type 'pdf' to assignments.

===How to use===

* Add a new Assignment to a course.
* Configure all the usual settings - you should be aware of the following additions:
** PDF submission - set to 'Yes' to allow students to submit PDFs for annotation
** PDF feedback - set to 'Yes' to allow the submitted PDFs to be annotated (note this ONLY works with PDFs submitted via the 'PDF submission' plugin).
** Coversheet - this is a PDF that will be automatically added to the start of any files submitted by your students
** Template - before submission your students can be (optionally) asked to fill in some text fields, the template is used to add these entries to the coversheet (this is ignored, if no coversheet is selected).
** Edit Templates... - see section below
It is recommended this is used with the 'Require students click submit button' option, as then the processing and combining of the submission PDFs is only done once they click that button. Otherwise, the processing is done every time the student updates their submission.

* When a student uploads their files and clicks 'Submit' they will be combined them together into a single submission (along with the coversheet).
(Hint: to help students generate PDF files, install a PDF printer, such as PDF Creator - http://sourceforge.net/projects/pdfcreator).
* The teacher can then log in, go to the usual marking screen and click on 'Annotate submission', which will bring up the first page of the student's work on screen.
* Click anywhere on the image of the PDF to add a comment. Use the resize handle in the bottom-right corner of a comment to resize it, click & drag on a comment to move it. Click (without dragging) on a comment to edit it, delete all the text in a comment to remove it.
* Right-click on a comment to add it to a 'Comment Quicklist'. You can then right-click anywhere on a page to insert comments from this 'Comment Quicklist' (with the same text, width and background as the original). Comments can be deleted from the 'Comment Quicklist' by clicking on the 'X' to the right of the comment.
* You can add lines to the PDF by holding 'Ctrl' ('Alt' on Apple Macs) whilst you click and drag with the mouse (or alternatively hold 'Ctrl' then click once for the start and once for the end of the line).
* You can also choose different drawing tools by clicking on the icons or by using the keys c (comments), l (lines), r (rectangles), o (ovals), f (freehand lines), e (erase lines), [ & ] (change comment colour), { & } (change line colour)
* Navigate between the pages by clicking on the 'Next' and 'Prev' buttons or by pressing 'n' and 'p' on the keyboard.
* Click on 'Save Draft and Close' (or just navigate to a different page) to save the work in progress.
* Click on the 'Generate Response' icon to create a new PDF with all your annotations present (that the student will be able to access).
* You can view the comments you have made on a student's previous submissions by choosing that submission from the 'compare to' list
* You can quickly find comments you have previously made by clicking on the 'find comment' list.
* Add any feedback / grades to the usual form and save them.

===Edit Templates===

* Click on the 'Edit Templates...' link on the 'Settings' page
* Choose the name of the Template to edit (or select 'New Template...')
* You can change the name of the template, delete the template or make it available to everyone on the site (administrators only, for this last option). Only administrators can edit site templates.
Note: you cannot delete templates that are in use (click 'show' to find out where it is currently being used)
* The list at the bottom allows you to choose an item in the template to edit, or choose 'New Item...' to add a new one.
* The types of item you can add are:
** text - a block of text, which will re-flow at 'width' pixels, 'value' will be the prompt the student sees to fill this in
** shorttext - similar to text, but without word-wrapping useful for 'name' or 'type your initials to state this is all your own work'
** date - fills in the date that the assignment was submitted, 'value' is the format to record the date
* To position the items on the template, upload an example PDF coversheet (using the bottom form) then type in the position you want to place the PDF (x position, y position, in pixels).
* Alternatively, click on the coversheet image to set the position of that template item.
* When you are finished, save any items you have changed, then close the window. The list of templates on the 'settings' page should have been updated.

===Known issues===

There is no way to annotate the PDFs without JavaScript.

Backup & restore will not transfer coversheet templates to a different site (it will work fine on a single site). This is a limitation of the assignment backup & restore process.

===Thanks===

This makes use of GhostScript and the FPDI and TCPDF libraries for PDF manipulation; Mootools is used to help with the JavaScript and Raphael provides the cross-browser annotation support.

Thanks to the creators of all those libraries, as this wouldn't have been possible without their hard work (and their free software licensing)
