Web/HTML to PDF

Apryse SDK allows you to convert html pages to PDF documents.

Android

Convert HTML to PDF in Xamarin.Android

This tutorial only applies to Xamarin.Android. See Xamarin.iOS equivalent here .

HTML to PDF conversion is available for Android API 19 and above.

Internet connection is not required when converting local HTML files. However, it is required for converting HTTP/HTTPS links.

The HTML to PDF conversion API accepts different sources, such as HTTP/HTTPS URLs, HTML strings, and everything that can be loaded in a WebView.

From link

To convert a link URL to PDF, simply:

HTML2PDF hTML2PDF = new HTML2PDF(this);
hTML2PDF.FromUrl("http://developer.android.com/about/index.html");
hTML2PDF.ConversionFinished += (sender, e) =>
{
    // do something with e.PdfOutput
};
hTML2PDF.ConversionFailed += (sender, e) =>
{
    // error handling
};

From HTML string

To convert an HTML string to PDF, simply:

HTML2PDF hTML2PDF = new HTML2PDF(this);
hTML2PDF.FromHTMLDocument(myBaseUrl, myHtmlData);
hTML2PDF.ConversionFinished += (sender, e) =>
{
    // do something with e.PdfOutput
};
hTML2PDF.ConversionFailed += (sender, e) =>
{
    // error handling
};

where myBaseUrl is the URL to use as the page's base URL. If null defaults to about:blank and myHtmlData is a String of data in the UTF-8 encoding.

From other sources

If none of the above fit your needs, you can also pass in a WebView directly for conversion:

HTML2PDF hTML2PDF = new HTML2PDF(myWebview);
hTML2PDF.DoHtml2Pdf();
hTML2PDF.ConversionFinished += (sender, e) =>
{
    // do something with e.PdfOutput
};
hTML2PDF.ConversionFailed += (sender, e) =>
{
    // error handling
};

iOS

Convert HTML to PDF in Xamarin.iOS

This tutorial only applies to Xamarin.iOS. See Xamarin.Android equivalent here .

Internet connection is not required when converting local HTML files. However, it is required for converting HTTP/HTTPS links.

The platform-specific conversion API also supports HTML to PDF conversion, either with the +convertOfficeToPDF:paperSize:completion: method for .html files or the +convertHTMLStringToPDF:baseURL:paperSize:completion: for raw HTML text.

The following code shows how to convert an HTML string to PDF:

pdftronprivate.PTConvert.ConvertHTMLStringToPDF(htmlString, baseURL, CGSize.Empty, (pathToPDF) => { 
    if (pathToPDF == null) {
        // Failed to convert HTML to PDF.
        return;
    }

    var documentDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

    var urlToPdf = new NSUrl(pathToPDF);
    var destinationURL = (new NSUrl(documentDirectory)).Append(urlToPdf.LastPathComponent, false);
    var destinationFileURL = NSUrl.CreateFileUrl(destinationURL.Path, null);

    NSError error = null;
    var result = NSFileManager.DefaultManager.Copy(urlToPdf, destinationFileURL, out error);
    if (!result) {
        // Failed to copy PDF to persistent location.
    }

    // Do something with PDF output.
});

where baseURL is the URL to use as the page's base URL for resolving relative links in the document.
