The ABCpdf .NET ABCWebKit runtime for HTML to PDF conversion using the WebKit rendering engine. The ABCWebKit engine uses a signed version of WkHtmlToPdf. It's HTML rendering is based on a modified version of the QtWebKit API from Qt4 for which support ended in 2015. It is provided as a workaround solution for more restrictive operating system environments such as with Azure App Services. Given its lack of support it is recommeneded that you do not use it with any untrusted HTML but only for HTML/JavaScript that you have complete control over.
Get Started
$ dotnet add package ABCpdf.ABCWebKitReadme
ABCWebKit
This is the ABCWebKit HTML conversion module.
It is intended for use with the ABCpdf NuGet package. ABCChrome will not function without it.
First you need to ensure you are using the correct namespace. Insert the following at the top of your C# module.
using WebSupergoo.ABCpdf13;
You select this HTML conversion module by setting the HtmlOptions.Engine property.
For example, if you are in a forms or console application, the following may be useful.
using (Doc doc = new Doc()) {
doc.HtmlOptions.Engine = EngineType.WebKit;
doc.AddImageUrl("http://www.google.com/");
doc.Save(@"C:\_output.pdf"); // adjust path for your needs
}
Alternatively if you are running under ASP.NET, you may want a Page_Load function something like this.
byte[] theData = null;
using (Doc doc = new Doc()) {
doc.HtmlOptions.Engine = EngineType.WebKit;
doc.AddImageUrl("http://www.google.com/");
theData = doc.GetData();
}
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "inline; filename=MyPDF.PDF");
Response.AddHeader("content-length", theData.Length.ToString());
Response.BinaryWrite(theData);
Response.End();
