Question

I am getting an error while deleting a page from an scanned pdf using TCPDF & FPDI. Other pdf are working fine.

ERROR: Unable to find object (8, 0) at expected location

Your file might be corrupted. Some scanners will produce corrupted PDF's, But nothing to worry there. You can recreate pdf if you are using linux with shell_exec

function pdf_recreate($f)
    {

        rename($f,str_replace('.pdf','_.pdf',$f));  

        $fileArray=array(str_replace('.pdf','_.pdf',$f));
        $outputName=$f;
        $cmd = "gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=$outputName ";

        foreach($fileArray as $file)
        {
          $cmd .= $file." ";
        }
        $result = shell_exec($cmd);
        unlink(str_replace('.pdf','_.pdf',$f));

    }

After recreation has completed,please delete pages . Hope this answer will solve your problems..
