public class FirstMain {
public static void main(String[] args) throws Exception {
Document doc = newDocument();
PdfWriter.getInstance(doc ,new FileOutputStream("f:\target.pdf"));
doc.open();
//定义一个块
Chunk chunk = newChunk("Cat");
//设置块的背景色
chunk.setBackground(Color.blue);
//字体
Font font =FontFactory.getFont(FontFactory.TIMES_BOLD);
font.setColor(Color.white);
chunk.setFont(font);
//增加块到文档
doc.add(chunk);
chunk = newChunk("DOG");
doc.add(chunk);
doc.close();
}
}
