Please take a look at the ListWithImageAsBullet example. It takes the image of a light bulb and uses it as if it were a bullet:
Image image = Image.getInstance(IMG); image.scaleAbsolute(12, 12); image.setScaleToFitHeight(false); List list = new List(); list.setListSymbol(new Chunk(Image.getInstance(image), 0, 0)); list.add("Hello World"); list.add("This is a list item with a lot of text. It will certainly take more than one line. This shows that the list item is indented and that the image is used as bullet."); list.add("This is a test"); document.add(list);
The result look like this:
