Winnovative PDF Chromium for .NET
|
|
Winnovative PDF Chromium for .NET integrates a new rendering engine enabling the conversion of all modern HTML, CSS and JavaScript content in conformance with the latest standards and technologies currently available.
The library can run on various Windows and Linux platforms and is compatible with Azure App Service and Azure Functions for both Windows and Linux.
The product is bundled and distributed as two separate NuGet packages for Windows and Linux including the same .NET Standard 2.0 library and different native runtimes. Targeting .NET Standard 2.0, makes the packages compatible with a large spectrum of .NET Core and .NET Framework versions.
The main functionality of the library is to convert HTML to PDF, HTML to image and Word (DOCX) to PDF. But the library does much more than this. You can automatically generate an outline with bookmarks for the generated PDF document, set permissions, password protect or digitally sign the generated PDF document.

| The ZIP package you can download from the link below includes a Visual Studio project for the ASP.NET Core demo application with C# sample code for all major library features.
The two folders for Windows and Linux include the same application, the only difference is the NuGet package referenced by each of them.
|
|
|
|
|
| On Windows, you can run the demo application from this package without any special setup.
On Linux, before running the demo application, you should first follow the steps from
online documentation
to setup the Linux machine.

HtmlToPdfConverter converter = new HtmlToPdfConverter();
// convert a HTML string to a memory buffer
byte[] htmlToPdfBuffer = converter.ConvertHtml("<b>Hello World</b> from EVO PDF !", null);
// write the memory buffer to a PDF file
System.IO.File.WriteAllBytes("HtmlToMemory.pdf", htmlToPdfBuffer);
|
|
|
To convert an URL to a PDF document in a memory buffer and then save the data from buffer into a file you can use the C# code below.
|
|
// create the converter object in your code where you want to run conversion
HtmlToPdfConverter converter = new HtmlToPdfConverter();
// convert an URL to a memory buffer
string htmlPageURL = "http://www.evopdf.com";
byte[] urlToPdfBuffer = converter.ConvertUrl(htmlPageURL);
// write the memory buffer to a PDF file
System.IO.File.WriteAllBytes("UrlToMemory.pdf", urlToPdfBuffer);

// convert a HTML string to a memory buffer
byte[] htmlToPdfBuffer = converter.ConvertHtml("<b>Hello World</b> from EVO PDF !", null);
FileResult fileResult = new FileContentResult(htmlToPdfBuffer, "application/pdf");
fileResult.FileDownloadName = "HtmlToPdf.pdf";
return fileResult;
|
