Converting HTML to GIF – Step by Step

Let’s break down the process of converting an HTML document to a GIF image into multiple steps:

Step 1: Prepare an HTML Code

String code = "<span>Hello</span> <span>World!!</span>";
try (java.io.FileWriter fileWriter = new java.io.FileWriter("document.html")) {
    fileWriter.write(code);
}

In this step, we create a simple HTML code containing the text “Hello World!!” and save it to a file named “document.html.”

Step 2: Initialize an HTML Document

HTMLDocument document = new HTMLDocument("document.html");

We initialize an HTML document by loading the HTML file created in Step 1.

ImageSaveOptions options = new ImageSaveOptions(ImageFormat.Gif);

Here, we create an ImageSaveOptions object and specify the output format as GIF.

Step 4: Convert HTML to GIF

Converter.convertHTML(document, options, "output.gif");

In this final step, we use the Converter class to convert the HTML document into a GIF image with the given options. The output GIF image will be saved as “output.gif.”
