How to POST Highcharts Image?

Question

I need to create a PDF file which contains Highcharts.js chart and just wondering if there is a way to optimize the Export module to POST the image (png or jpeg) to a PHP file which I want to create the PDF files there.

As you know the exporting module normally exports the output as downloadable files but I do not want to download them just send them on the server.

Thanks

You can use highchart's exporting module along with TCPDF Library. The TCPDF library Support svg rendaring.

You can use the exportApi

   chart.exportChart({
             url : 'export.php',
             filename: 'my-chart'
        }); 

Then use the example script a modified version from original SVG pdf example

Main part of the code is

$pdf->ImageSVG expect first parameter as string Name of the SVG file or a '@' character followed by the SVG data string.

$pdf->ImageSVG("@".$_POST['svg'], $x=15, $y=30, $w=200);

Happy coding!!

NB: You need to download the TCPDF library
