pdftoppm (from poppler-utils package) is several orders of magnitude quicker than ghostscript extracting PNG images from PDF documents. We add support for this tool and use it whenever set up, or using gs as before if missing. Revisited code with peer review comments. In particular: 1. Make default path for pdftoppm empty string. 2. Fix a typo on the method description for get_gs_command_for_image. 3. Added more information why is useful pdftoppm into string pathtopdftoppm_help. 4. Check that path for pdftoppm is executable to prevent errors. Otherwise, use gs.
ACTIVITY MODULES
----------------
These are main modules in Moodle, allowing various activities.
Each of these modules contains a number of expected components:
mod_form.php: a form to setup/update a module instance
version.php: defines some meta-info and provides upgrading code
pix/icon.gif: a 16x16 icon for the module
db/install.xml: an SQL dump of all the required db tables and data
index.php: a page to list all instances in a course
view.php: a page to view a particular instance
lib.php: any/all functions defined by the module should be in here.
constants should be defined using MODULENAME_xxxxxx
functions should be defined using modulename_xxxxxx
There are a number of standard functions:
modulename_add_instance()
modulename_update_instance()
modulename_delete_instance()
modulename_user_complete()
modulename_user_outline()
modulename_cron()
modulename_print_recent_activity()
