Whether you're a seasoned developer or just starting your journey in the world of .NET programming, this tutorial will guide you through the essentials of Aspose.HTML, from importing namespaces to breaking down practical examples. |
| 12 | + |
| 13 | +## Introduction |
| 14 | + |
| 15 | +Aspose.HTML for .NET is a versatile library that enables developers to manipulate HTML documents with ease. Whether you need to convert HTML to other formats, extract data from HTML documents, or create dynamic HTML content, Aspose.HTML has you covered. In this tutorial, we will explore its capabilities step by step. |
| 16 | + |
| 17 | +## Prerequisites |
| 18 | + |
| 19 | +Before we dive into the code examples, you'll need a few prerequisites: |
| 20 | + |
| 21 | +1. Visual Studio: Ensure you have Visual Studio installed, as we'll be writing .NET code. |
| 22 | + |
| 23 | +2. Aspose.HTML for .NET: Download and install the Aspose.HTML for .NET library from [this link](https://releases.aspose.com/html/net/). You can choose between the free trial or purchasing a license [here](https://purchase.aspose.com/buy). |
| 24 | + |
| 25 | +3. .NET Framework or .NET Core: Make sure you have either the .NET Framework or .NET Core installed on your development machine, depending on your project requirements. |
| 26 | + |
| 27 | +4. A Code Editor: You can use Visual Studio or any other code editor of your choice. |
| 28 | + |
| 29 | +## Importing Namespaces |
| 30 | + |
| 31 | +To get started with Aspose.HTML for .NET, we first need to import the necessary namespaces. Open your project in Visual Studio, create a new C# class, and import the following namespaces: |
| 32 | + |
12 | 33 | ```csharp |
13 | | - public static void Run() |
14 | | - { |
15 | | - // ExStart:1 |
16 | | - string dataDir = "Your Data Directory"; |
17 | | - using (var document = new Aspose.Html.HTMLDocument("<style>p { color: green; }</style><p>my first paragraph</p>", @"c:\work\")) |
18 | | - { |
19 | | - using (HtmlRenderer renderer = new HtmlRenderer()) |
20 | | - using (ImageDevice device = new ImageDevice(dataDir + @"document_out.png")) |
21 | | - { |
22 | | - renderer.Render(device, document); |
23 | | - } |
24 | | - } |
25 | | - // ExEnd:1 |
26 | | - } |
| 34 | +using Aspose.Html; |
| 35 | +using Aspose.Html.Converters; |
| 36 | +using Aspose.Html.Rendering; |
| 37 | +using Aspose.Html.Rendering.Image; |
27 | 38 | ``` |
| 39 | + |
| 40 | +These namespaces provide access to various classes and methods required for working with HTML documents programmatically. |
| 41 | + |
| 42 | +## Render HTML as PNG Example |
| 43 | + |
| 44 | +Let's take a closer look at the code example you provided and break it down into multiple steps: |
| 45 | + |
| 46 | +```csharp |
| 47 | +// Render HTML as PNG in .NET with Aspose.HTML |
| 48 | +string dataDir = "Your Data Directory"; |
| 49 | + |
| 50 | +// Step 1: Create an HTML document object |
| 51 | +using (var document = new Aspose.Html.HTMLDocument("<style>p { color: green; }</style><p>my first paragraph</p>", @"c:\work\")) |
| 52 | +{ |
| 53 | + // Step 2: Create an HTML renderer |
| 54 | + using (HtmlRenderer renderer = new HtmlRenderer()) |
| 55 | + using (ImageDevice device = new ImageDevice(dataDir + @"document_out.png")) |
| 56 | + { |
| 57 | + // Step 3: Render the HTML document to PNG |
| 58 | + renderer.Render(device, document); |
| 59 | + } |
| 60 | +} |
| 61 | +``` |
| 62 | + |
| 63 | +### Step 1: Create an HTML Document Object |
| 64 | + |
| 65 | +In this step, we create an `HTMLDocument` object, which represents an HTML document. You can pass the HTML content as a string to the constructor, and you can also specify the base path for resolving relative paths. |
| 66 | + |
| 67 | +### Step 2: Create an HTML Renderer |
| 68 | + |
| 69 | +Here, we create an `HtmlRenderer` object. This is the core component responsible for rendering HTML content. |
| 70 | + |
| 71 | +### Step 3: Render the HTML Document to PNG |
| 72 | + |
| 73 | +Finally, we render the HTML document to a PNG image using the `HtmlRenderer` and an `ImageDevice`. The resulting PNG image will be saved in the specified `dataDir`. |
| 74 | + |
