Winnovative Server

Winnovative Server package contains the server files and detailed installation instructions for each platform. You can start by installing Winnovative Server as a Windows Service on the local development machine with default options. In this case the assigned IP address is 127.0.0.1.

After the Winnovative Server was installed, you are ready to use the Winnovative HTML to PDF Client Library for UWP in your applications.

C# Code Samples

Copy the C# code lines from the section below to create a PDF document from a web page or from a HTML string and save the resulted PDF to a memory buffer for further processing or to a PDF file.

The server IP address is assigned during server installation and it can be omitted from HtmlToPdfConverter constructor if the server was installed on the localhost IP address 127.0.0.1 . There are also variants of the constructor accepting an URL instead of IP address if the server was installed as a web service in Azure or in IIS.

At the top of your C# source file add the using Winnovative.HtmlToPdfClient; statement to make available the Winnovative HTML to PDF Client API for your .NET application.

// add this using statement at the top of your C# file
using Winnovative.HtmlToPdfClient;

To convert in your UWP application a HTML string to a PDF document in a memory buffer, save it to a file and open that file a in PDF viewer you can use the C# code below.

// create the converter object in your code where you want to run conversion
// change the serverIP value if the server was installed on a remote machine
string serverIP = "127.0.0.1";
HtmlToPdfConverter converter = new HtmlToPdfConverter(serverIP);

// convert a HTML string to a memory buffer
byte[] htmlToPdfBuffer = converter.ConvertHtml("<b>Hello World</b> from Winnovative !", null);

// write the memory buffer to a PDF file
Windows.Storage.StorageFolder installedLocation = Windows.Storage.ApplicationData.Current.LocalFolder;
StorageFile htmlToPdfStorageFile = installedLocation.CreateFileAsync("HtmlToMemory.pdf", 
            CreationCollisionOption.ReplaceExisting).AsTask().Result;
FileIO.WriteBytesAsync(htmlToPdfStorageFile, htmlToPdfBuffer).AsTask().Wait();

// open the PDF file in a PDF viewer
await Windows.System.Launcher.LaunchFileAsync(htmlToPdfStorageFile);

To convert in your UWP application an URL to a PDF document in a memory buffer, save it to a file and open that file in a PDF viewer you can use the C# code below.

// create the converter object in your code where you want to run conversion
// change the serverIP value if the server was installed on a remote machine
string serverIP = "127.0.0.1";
HtmlToPdfConverter converter = new HtmlToPdfConverter(serverIP);

// convert an URL to a memory buffer
string htmlPageURL = "http://www.winnovative-software.com";
byte[] urlToPdfBuffer = converter.ConvertUrl(htmlPageURL);

// write the memory buffer to a PDF file
Windows.Storage.StorageFolder installedLocation = Windows.Storage.ApplicationData.Current.LocalFolder;
StorageFile urlToPdfStorageFile = installedLocation.CreateFileAsync("UrlToMemory.pdf", 
            CreationCollisionOption.ReplaceExisting).AsTask().Result;
FileIO.WriteBytesAsync(urlToPdfStorageFile, urlToPdfBuffer).AsTask().Wait();
            
// open the PDF file in a PDF viewer
await Windows.System.Launcher.LaunchFileAsync(urlToPdfStorageFile);
