PDF小丑:创建列表

标签: java pdf pdfclown

我希望使用Java Clown in Java以编程方式创建PDF文件。我需要使用带有子弹点的列表。这是否可以使用PDF Clown的当前稳定版本?如果是这样,我应该在API文档中查看哪个类?我在文档中搜索了列表,但是没有提到它。

在没有特定支持的情况下,我能想到的唯一方法就是使用带有X偏移的BlockComposer,但这不会有Bullet点。任何解决方案?

我意识到这个功能计划用于PDF Clown(0.2.0)的下一个版本,但是我等它太远了。

你可以这样做 enter image description here

import org.pdfclown.documents.contents.colors.DeviceRGBColor;
import org.pdfclown.documents.contents.composition.*;

. . .

DocumentComposer composer = new DocumentComposer(document);

/*
  We decide that table cells sport a solid border by default (analogous 
  to CSS styles defined through an element type selector).
*/
composer.getStyle(Cell.class)
  .withBorder(new Border(
    new QuadColor(new DeviceRGBColor(0, 0, 0)),
    new QuadBorderStyle(BorderStyleEnum.Solid),
    new QuadLength(new Length(1)),
    new QuadCornerRadius()))
  .withPadding(new QuadLength(new Length(5)));

/*
  The list will be included in a section.
*/
Section section = new Section("Hello World, this is PDF Clown!");

/*
  This is the actual list composition.
*/
List list = new List(
  new ListItem("Item 1"),
  new ListItem("Item 2"),
  new ListItem(
    /* We decide that this list item has an arbitrary 5pt margin. */
    new Style().withMargin(new QuadLength(new Length(5))),
    "Item 3 (margin: 5pt)"
    ),
