EVO PDF Client for .NET Documentation

EVO HTML to PDF Converter also allows you to easily convert in just a few lines of code HTML pages and HTML strings to vector images in SVG format. In this section you can learn about the basic settings of the converter.

You can choose the HTML document to convert which can be:

The basic options you can set are grouped in a few categories.

HTML Viewer Options

  • HTML Viewer Width. This option is the equivalent in converter of the browser window width. The property you can set in your code to control the browser window width is HtmlToSvgConverterHtmlViewerWidth. When the browser window width is changed the HTML content displayed inside the window can have a different layout and something similar happens when you change the HTML Viewer width of the converter. At a given viewer width, the converter will capture by default the whole height of the HTML content, but you can set the HTML Viewer height to capture only the top part of the HTML page

  • HTML Viewer Height. This option is the equivalent in converter of the browser window height and can be used to limit the conversion to the top part of the HTML page. If this property is not set the entire page will be converted. The property you can set in your code to control the browser window height is HtmlToSvgConverterHtmlViewerHeight

C#
protected void convertToSvg()
{
    // Get the server IP and port
    String serverIP = textBoxServerIP.Text;
    uint serverPort = uint.Parse(textBoxServerPort.Text);

    // Create a HTML to SVG converter object
    HtmlToSvgConverter htmlToSvgConverter = null;
    if (radioButtonUseTcpService.Checked)
        htmlToSvgConverter = new HtmlToSvgConverter(serverIP, serverPort);
    else
        htmlToSvgConverter = new HtmlToSvgConverter(true, textBoxWebServiceUrl.Text);

    // Set optional service password
    if (textBoxServicePassword.Text.Length > 0)
        htmlToSvgConverter.ServicePassword = textBoxServicePassword.Text;

    // Set license key received after purchase to use the converter in licensed mode
    // Leave it not set to use the converter in demo mode
    htmlToSvgConverter.LicenseKey = "4W9+bn19bn5ue2B+bn1/YH98YHd3d3c=";

    // Set HTML Viewer width in pixels which is the equivalent in converter of the browser window width
    htmlToSvgConverter.HtmlViewerWidth = int.Parse(htmlViewerWidthTextBox.Text);

    // Set HTML viewer height in pixels to convert the top part of a HTML page 
    // Leave it not set to convert the entire HTML
    if (htmlViewerHeightTextBox.Text.Length > 0)
        htmlToSvgConverter.HtmlViewerHeight = int.Parse(htmlViewerHeightTextBox.Text);

    // Set the maximum time in seconds to wait for HTML page to be loaded 
    // Leave it not set for a default 60 seconds maximum wait time
    htmlToSvgConverter.NavigationTimeout = int.Parse(navigationTimeoutTextBox.Text);

    // Set an adddional delay in seconds to wait for JavaScript or AJAX calls after page load completed
    // Set this property to 0 if you don't need to wait for such asynchcronous operations to finish
    if (conversionDelayTextBox.Text.Length > 0)
        htmlToSvgConverter.ConversionDelay = int.Parse(conversionDelayTextBox.Text);

    // The buffer to receive the generated SVG document
    byte[] outSvgBuffer = null;

    if (convertUrlRadioButton.Checked)
    {
        string url = urlTextBox.Text;

        // Convert the HTML page given by an URL to a SVG document in a memory buffer
        outSvgBuffer = htmlToSvgConverter.ConvertUrl(url);
    }
    else
    {
        string htmlString = htmlStringTextBox.Text;
