Pdf Rendering Problem With Phpexcel

Hi All,

I have been trying to use the PHPExcel extension to generate PDF but keep on getting the error : "PDF Rendering library has not been defined."

I know the PDF Rending Library and the path for the library has to be defined in Yii inorder to render it to PDF. But I dont know where and how to set it.

Any one of you have tried this before. Let me know.
