HTML to PDF Conversion Using ASP.NET Core in Linux Docker

Docker is a lightweight and very popular container platform that packages an application with everything it needs to run, with the necessary code, system libraries, fonts, other supported libraries, or files. 

Visual Studio 2017 and Docker support building and running .NET applications using a Windows docker container and .NET Core application on Linux docker containers.

Syncfusion HTML to PDF converter can be easily integrated into any application with five simple lines of code. Using this library, you can turn an entire webpage into a PDF file. Or just convert a portion of the page. Your PDF will just look like the webpage you converted—it preserves all graphics, images, text, fonts, links, and the layout of the original HTML document or webpage.

Furthermore, Syncfusion HTML to PDF converter is available in Windows Forms, WPF, ASP.NET, ASP.NET MVC, and ASP.NET Core. In this post, I use ASP.NET Core in a Linux Docker container.

Setup

Can you show us some code?

//Initialize HTML to PDF converter
HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter();
//Set WebKit path
htmlConverter.ConverterSettings.WebKitPath = Path.Combine(_hostingEnvironment.ContentRootPath, "QtBinaries");
//Convert URL to PDF
PdfDocument document = htmlConverter.Convert("https://www.google.com");
MemoryStream ms = new MemoryStream();
//Save and close the PDF document
document.Save(ms);
document.Close(true);

Include the below snippet in the docker file to install the dependent packages in the docker container.

This sample is made as simple as possible for converting a webpage to PDF.
