Take Website Screenshots with ASP.NET
There are several ways that the GrabzIt API can be used to take screenshots and more in ASP.NET. To get started with the API follow these steps:
- Get your free Application Key and Secret.
- Download the free ASP.NET Library and try out the Demo Application.
- Find out the basics about how GrabzIt's API works by reading the below overview.
ASP.NET API Overview
To use the API you will first need to create an instance of the GrabzItClient class, passing your application key and application secret from your GrabzIt account to the constructor. As shown in the below example, note that while all of our ASP.NET examples are written in C# any ASP.NET language will work with this library.
//Create the GrabzItClient class
//Replace "APPLICATION KEY", "APPLICATION SECRET" with the values from your account!
private GrabzItClient grabzIt = GrabzItClient.Create("Sign in to view your Application Key", "Sign in to view your Application Secret");
Then use one of the image, PDF, animation or table methods to capture a URL or convert HTML.
// To take a image screenshot
// Or to take a PDF screenshot
// Or to convert online videos into animated GIF's
// Or to capture table(s)
// To convert HTML into a image
// Or convert HTML into a PDF document
// Or convert HTML into a CSV, XLSX or JSON document
// To convert HTML file into a image
// Or convert HTML file into a PDF document
// Or convert HTML file into a CSV, XLSX or JSON document
Next call either the
SaveTo method. Below are two examples of the calling the
Save method, one using MVC and another using Web Forms, both of these examples include the URL to the handler, which will process the callback from the service and save the resulting capture. As this method requires a callback handler it is usually only possible to use this approach in a web application.
Alternatively the synchonous SaveTo method, this will force your application to wait while the screenshot is created so it should only be used were the Save method cannot be used, such as in a desktop application. Once the screenshot is created it is saved to the file path provided.
string filepath = "images/result.jpg";
All of our services such as creating web captures, animated GIF's or converting HTML have many customizable options including; configuring the browser height, browser width, screenshot height, screenshot width, the delay before a screenshot is taken and the image format of the screenshot. For all these options please see the Client documentation.
