// PHPThumb Output Filter
//
// By Jared Loman a.k.a jtech - http://www.jaredloman.com
//
// GitHub: http://github.com/jaredloman/PHPthumb-Output-Filter
//
// Revision by Djordje Dimitrijev (dj13 on Modx forum)
//
// Revision Notes:
//
// Choose the output from a script:
// 1. Full image tag.
// 2. Only src value (additional attributes will not be used).
// Added possibility use or not high security password from phpThumb config.
// Possibility to add as much as you want default image attributes through the array.
// New way to add attributes in filter:
// attribute_html_name || attribute_value
//
// Version 0.6 beta
//
// Current Version Notes:
// Fixed the removal of source only option (oops!)
// Added support to make image urls generated W3C compliant
//
// Previous Version Notes:
// v.0.5: Now utilizes the default phpthumb included with Revo!
// v.0.5: I'm not sure if the high security options continue to be functional.
// v.0.4: Added Source only option (by DJ13)
// v.0.3: Added possibility use or not high security password from phpThumb config.
// v.0.3: Possibility to add as much as you want default image attributes through the array.
// v.0.3: New way to add attributes in filter:
// v.0.3: attribute_html_name || attribute_value
//
// v.0.2: Added array to handle "class" & "alt" options with defaults.
// v.0.2: Added a space removal fool-proof in case someone trys to skip the class and add an alt.
// v.0.2: Added Readme
// v.0.2: Still haven't tested all phpthumb modifiers.
//
// v.0.1: I haven't tested all of the phpthumb modifiers, but I think they should work
// ReadMe:
//
// Notes:
// I created the PHPThumb output filter so that I could have some flexibility with my images that an output modifier
// couldn't offer me. This output filter is essentially useless for anything other than images (Obviously!), but I
// figured I'd at least mention this.
//
// This does not support PHPThumbs ability to create new images from nothing. It would be kind of silly to use a
// TV and Output filter for this purpose anyhow.
//
// INSTRUCTIONS:
// Step 1.) Create a TV with an input type of "IMAGE" and an output type of "TEXT".
// Step 2.) Add an image to the TV.
// Step 3.) Add your TV to your page content or template and modify in the format of the example.
//
// OPTIONS:
// Option 1.) The first option is the phpthumb modifications. You can add any modifier that phpthumb supports. (AFIK)
//
// IMPORTANT:
// TV Output Type MUST be "TEXT"!!
//
// Examples:
//
// Filter full image tag: [[*mytvImage:phpthumb=`&w=100&h=50&zc=1,class||myClass,title||myTitle,style||border: 1px solid #333`]]
// Filter only src output: [[*mytvImage:phpthumb=`&w=100&h=50&zc=1,onlysrc||1`]]
//
// Snippet full image tag: [[phpthumb? &input=`files/myImage.jpg` &options=`&w=100&h=50&zc=1,class||myClass,title||myTitle`]]
// Snippet only src output v1 (best way if You want only src): [[phpthumb? &input=`files/myImage.jpg` &options=`&w=100&h=50&zc=1` &onlysrc=`1`]]
// Snippet only src output v2: [[phpthumb? &input=`files/myImage.jpg` &options=`&w=100&h=50&zc=1,onlysrc||1`]]
//
$phpthumb_path = 'connectors/system';
// Define attribute name - value separator
$attribute_sep = '||';
$base = $modx->config['base_url'];
// Default array of attributes with key name like html attribute name. Lowercase for keys.
// Examples:
// $attributes['style'] = 'border:1px solid #ccc;'
// $attributes['title'] = 'My Title';
// $attributes['class'] = 'myClass';
//
// IMPORTANT! If You set:
// $output_onlysrc = 1;
// all returns from snippet will be only src
$output_onlysrc = false;
$error = "You need to specify at least one option, otherwise this filter is pointless!";
if(!empty($options)){$phpthmbOptions = explode(",", $options);}else{$output = $error; return $output;}
// Include phpThumb config file.
// require_once($modx->getOption('base_path') . $phpthumb_path . '/phpThumb.config.php');
