Path issues

Very handy!

In the documentation, it would be good to specify the font file type required -- took me a little digging to figure out that I needed to call TTF fonts with the basename of the font and that my font needed to have a lowercase extension on it.

Also, it did not work by default with alternate path routines-- I had to alter the ETextimage.php run method as follows (now it will work no matter what configuration the application uses):

/**

• Renders the widget. */ public function run() { $this->textImage=urlencode(base64_encode($this->textImage)); $base = $this->getController()->getId().'/'.$this->thisAction; $params = array( 'textImage'=>$this->textImage, 'fontSize'=>$this->fontSize, 'fontFile'=>$this->fontFile, 'backColor'=>$this->backColor, 'foreColor'=>$this->foreColor, 'transparent'=>$this->transparent, 'v'=>rand(0,10000) );

echo CHtml::image( Yii::app()->createUrl( $base, $params ) ,''); }

没看明白具体怎么用？ 请教
