If the EVO PDF Server is installed on the same Windows machine where you run your application then the HTML to PDF Converter client object constructor does not need additional parameters.
A typical scenario for this usage case is when you install the EVO PDF Server in a Windows Service on the same machine running the client library.
The client HTML to PDF Converter object above will try to connect to the EVO PDF Server installed on the localhost default IP address 127.0.0.1 on the default TCP port 40001.
using EvoPdfClient; HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(); byte[] outPdfBuffer = htmlToPdfConverter.ConvertUrl(url);
If the EVO PDF Server was installed as a TCP/IP server on a remote machine then you'll have to specify the HTML to PDF Service IP address in the HTML to PDF Converter client object constructor.
A typical scenario for this usage case is when you install the EVO PDF Server in an Azure Cloud Service Worker Role, in an in an Azure Service Fabric Application or in a Windows Service on a remote Windows machine.
The code below initializes a HTML to PDF Converter object that will connect to to a server running on a specified IP address and TCP port. If the port is not specified then the default port 40001 will be used.
using EvoPdfClient; HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(serverIP, serverPort); byte[] outPdfBuffer = htmlToPdfConverter.ConvertUrl(url);
If the EVO PDF Server was installed as a HTTP server on a remote machine then you'll have to specify the HTML to PDF Service HTTP URL address in the HTML to PDF Converter client object constructor.
A typical scenario for this usage case is when you install the EVO PDF Server in an Azure Cloud Service Web Role or in an IIS ASP.NET Web Application.
The code below initializes a HTML to PDF Converter object that will connect to to a server running at a specified HTTP URL.
using EvoPdfClient; HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(true, serverHttpUrl); byte[] outPdfBuffer = htmlToPdfConverter.ConvertUrl(url);
