NAME
   RT::Extension::Captcha - solve a CAPTCHA before some actions in RT

DESCRIPTION
   This extension is for RT 3.8.1 or newer. It requires solving captchas
   when a user creates a ticket (using either regular interface or quick
   create) and on replies/comments (updates).

INSTALLATION
   perl Makefile.PL
   make
   make install
       May need root permissions

   Edit your /opt/rt4/etc/RT_SiteConfig.pm
       If you are using RT 4.2 or greater, add this line:

           Plugin('RT::Extension::Captcha');

       For RT 4.0, add this line:

           Set(@Plugins, qw(RT::Extension::Captcha));

       or add RT::Extension::Captcha to your existing @Plugins line.

   Clear your mason cache
           rm -rf /opt/rt4/var/mason_data/obj

   Restart your webserver

CONFIGURATION
 No CAPTCHA rights
   Users who have right 'NoCaptchaOnCreate' or 'NoCaptchaOnUpdate' will see
   no captchas on corresponding actions.

 Font
   As GD's builtin font is kinda small. A ttf font is used instead. By
   default font defined by ChartFont option (RT's option to set fonts for
   charts) is used for CAPTCHA images.

   As well, you can set font for cpatchas only using "%Captcha option"
   described below.

 %Captcha option
   See etc/Captcha_Config.pm for defaults and example. %Captcha option is a
   hash. Now, only ImageProperties key has meaning:

       Set(%Captcha,
           ImageProperties => {
               option => value,
               option => value,
               ...
           },
       );

   ImageProperties are passed into "new" in GD::SecurityImage. Read
   documentation for the module for full list of options.
