text-image-generator example

As a follow-up on my previous post, here is an example of how to use the text-image generation library. Consider the following code:

        TextImage   testImage = new TextImageImpl(400, 250, new Margin(0, -5));
    
        // Declare or read the fonts you need
        Font header = new Font("Sans-Serif", Font.BOLD, 15);
        Font plain = new Font("Sans-Serif", Font.PLAIN, 12);
        
        // Read in any images you need
        InputStream is = Test.class.getResourceAsStream("/warning.jpg");
        Image warning = ImageIO.read(is);
        // Put close() in try-finally block with production code! 
        is.close();
        
        // 1. specify font and write text with a newline
        testImage.useFont(header).writeLine("Example usage text-image-generator.").newLine();
        // 2. enabled the wrapping of text and write text which is automatically wrapped 
        testImage.useFont(plain).wrap(true).write("This is an example of how to use the text-image generation library. With this library you can dynamically generated textbased content as images (png or jpeg). Notice how this sentence is automatically wrapped. See the code at http://code.google.com/p/textimagegenerator/ for more examples.").newLine();
        
        // 3. Disable text-wrapping again. Write underlined text.
        testImage.wrap(false).useColor(Color.BLUE).useFontStyle(Style.UNDERLINED).write("This line of text is underlinedand blue.").useFontStyle(Style.PLAIN).newLine();
        testImage.writeLine("You can also embed images in your generated image:");
        // 4. embed the actual image. Here we use absolute positioning
        testImage.write(warning, 175, 175);
        
        // 5. Write the image as a png to a file
        OutputStream os = new FileOutputStream(new File("example.png"));
        testImage.createPng(os);
        os.close();

The code above generates the following image:
