Content is not compatible as a PDF, using Snappy wkhtmltopdf

I'm working on a project. I'm trying to generate a report with my charts and dynamic tables. I tried to used wkhtmltopdf but I wasn't able to deal with the complexity. However, I read most of the answered to other question on wkhtmltopdf so I decided to try snappy which was a sugeestion. below is my code.

  require_once 'C:/wamp/www/Mamca/lib/snappy/src/autoload.php';

  use Knp\Snappy\Pdf;

  $snappy = new Pdf('/usr/local/bin/wkhtmltopdf');
  header('Content-Type: application/pdf');
  header('Content-Disposition: attachment; filename="file.pdf"');
  echo $snappy->getOutput('http://www.github.com');

but the pdf generated does not open, error from the pdf reader states "cannot open file"

There is no need for working with snappy to convert html to pdf. After spending one day on snappy, i used simple exec() function of php to convert html into pdf.

$exe_path = '..path to your exe file..\wkhtmltopdf.exe';
$file_html_path = '..path of your html file..\report.html';
$file_pdf_path  = '..path of your pdf file..\report.pdf';

$cmd = <<<EOT
"$exe_path" --orientation "Landscape" --page-size "A4" --viewport-size 
"1280x1024" "$file_html_path" "$file_pdf_path" 2>&1
EOT;

//echo $cmd;die;
exec($cmd,$output,$return); 


Please note here:
$cmd is a command 
$output will return response of exec execute successfully or return error code and message
$return will return a boolean value 0 or 1 zero means success or 1 means error

require_once 'C:/wamp/www/Mamca/lib/snappy/src/autoload.php';

use Knp\Snappy\Pdf;

**$snappy = new Pdf('C://DEV/wkhtmltopdf/bin/wkhtmltopdf.exe');**
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="file.pdf"');
echo $snappy->getOutput('http://www.github.com');

I just changed the path of the wkhtmltopdf and it worked.
