Can't figure out how to use WKHTMLTOPDF and getting a hash error

Here is the code with 3 different methods, but none work and seem to be relating to what is surrounding the filenames

 
use WKHTMLTOPDF;
$filename='test.html';
$path='/temp/';
$inputfile="$path$filename";
$outputfilename='TEST';
$ext='.pdf';
$outputfile="$path$outputfilename$ext";
my $pdf = new WKHTMLTOPDF;
$pdf->_input_file('/temp/TEST.html');
$pdf->_output_file('/temp/TEST.pdf');
$pdf->_input_file('$inputfile');
$pdf->_output_file('$outputfile');
$pdf->grayscale(1);
$pdf->generate;

#system ("cd C:\Program Files\wkhtmltopdf\bin");
#system ('start "C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf $inputfi
+le $outputfile"');
#system ('start "C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf /temp/TE
+ST.html /temp/TEST.pdf"');
