1. Requirements
2. Usage

This extension generates thumbnails by images jpg/jpeg, png or gif format. There are many parameters like width,height, source, destination folder etc that you can manage

Requirements ¶

Developed and tested with Yii 1.1.12 but may working with older versions too. GD library PHP

Usage ¶

1) Extract archive in your extensions folder 2) In the site root create a folder named "images" if it not exist and extract your images

3) in components part of config/main.php put this code

'ThumbsGen' => array(
                  'class' => 'application.extensions.ThumbsGen.ThumbsGen',
            ),

Alternatively you could put this code in your controller that have to generate the thumbnails

Yii::app()->setComponents(array('ThumbsGen' => array(
                'class' => 'ext.ThumbsGen.ThumbsGen',
            )));

4) Now you can generate the thumbnails in Controller by this code

Yii::app()->ThumbsGen->createThumbnails();

5) If you want to get the full pathname of thumbnails in array, call

Yii::app()->ThumbsGen->getThumbsUrl();

Notes: You could use this components with full parameters issue (initialize):

Yii::app()->setComponents(array('ThumbsGen' => array(
'class' => 'ext.ThumbsGen.ThumbsGen',
'scaleResize' => null, //if it is not null $thumbWidth and $thumbHeight will be ommited. for example 'scaleResize'=>0.5 generate image with half dimension
//one of $thumbWidth or $thumbHeight is optional but not both!
'thumbWidth' => 200, //the width of created thumbnail on pixel. if height is null the aspect ratio will be reserved
'thumbHeight' => null, //the height of created thumbnail on pixel. if width is null the aspect ratio will be reserved
'baseSourceDir' =>  Yii::getPathOfAlias('webroot.images'), //the main direcory of source images. if set to null the destination dir is the <webroot>/images
'baseDestDir' =>  Yii::getPathOfAlias('webroot.images.thumbs'), //the main direcory of thumbnails. if set to null the destination dir is the <webroot>/images/thumbs
'postFixThumbName' => '_thumb', //the postfix name of thumbnail for example if it set = '_thumb' then  image1.jpg become image1_thumb.jpg
'nameImages' => array('*'), //the names of images into $baseSourceDir, for example ('01.jpg','03.jpg'). the asterisk means all files jpg/jpeg, png or gif
'recreate' => true, //force to create each thumbnail either exist or not, when is set to false the tumbnails created only in the first time
          )));
