Java如何实现长图文生成的示例代码

@Getter @Setter @ToString public class ImgCreateOptions {       private BufferedImage bgImg;        private Integer imgW;     private Font font = new Font("宋体", Font.PLAIN, 18);       private Color fontColor = Color.BLACK;        private int leftPadding;       private int topPadding;       private int bottomPadding;       private int linePadding;     private AlignStyle alignStyle;       public enum AlignStyle {     LEFT,     CENTER,     RIGHT;       private static Map<String, AlignStyle> map = new HashMap<>();      static {       for(AlignStyle style: AlignStyle.values()) {         map.put(style.name(), style);       }     }       public static AlignStyle getStyle(String name) {       name = name.toUpperCase();       if (map.containsKey(name)) {         return map.get(name);       }        return LEFT;     }   } }
