PHP ImageManager::_getImageSize方法代碼示例

 /**
  * Create thumbnails and update the corresponding Product records
  *
  * Scans the Products with the given IDs.  If a non-empty picture string
  * with a reasonable extension is encountered, determines whether
  * the corresponding thumbnail is available and up to date or not.
  * If not, tries to load the file and to create a thumbnail.
  * If it succeeds, it also updates the picture field with the base64
  * encoded entry containing the image width and height.
  * Note that only single file names are supported!
  * Also note that this method returns a string with information about
  * problems that were encountered.
  * It skips records which contain no or invalid image
  * names, thumbnails that cannot be created, and records which refuse
  * to be updated!
  * The reasoning behind this is that this method is currently only called
  * from within some {@link _import()} methods.  The focus lies on importing
  * Products; whether or not thumbnails can be created is secondary, as the
  * process can be repeated if there is a problem.
  * @param   integer     $arrId      The array of Product IDs
  * @return  boolean                 True on success, false on any error
  * @global  ADONewConnection  $objDatabase    Database connection object
  * @global  array
  * @static
