在文档中添加超链接，可以快速从当前文档跳转至指定的网页或打开指定的外部文件。前文中我们介绍过如何使用Java程序来为Word文档和Excel工作表添加超链接。本文将演示如何在PPT中添加文本和图片超链接。
使用工具：Free Spire.Presentation for Java（免费版）Jar文件获取及导入：
方法1：通过官网下载获取jar包。解压后将lib文件夹下的Spire.Presentation.jar文件导入Java程序。（如下图）
方法2：通过maven仓库安装导入。具体安装教程参见此网页。
【示例1】添加文本超链接
import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;
import java.awt.*;
import java.awt.geom.Rectangle2D;
public class TextHyperlink {
public static void main(String[] args) throws Exception {
//创建一个PPT文档,默认包含一张幻灯片
Presentation presentation = new Presentation();
//在文档最后追加一张幻灯片并填充一些内容，方便之后添加超链接链接到此幻灯片
presentation.getSlides().append();
Rectangle2D.Double rec = new Rectangle2D.Double(presentation.getSlideSize().getSize().getWidth() / 2 - 255, 120, 500, 280);
IAutoShape shape = presentation.getSlides().get(1).getShapes().appendShape(ShapeType.RECTANGLE, rec);
shape.getFill().setFillType(FillFormatType.NONE);
shape.getLine().setWidth(0);
ParagraphEx para1 = new ParagraphEx();
PortionEx tr1 = new PortionEx();
tr1.setText("这是第二页！");
para1.getTextRanges().append(tr1);
shape.getTextFrame().getParagraphs().append(para1);
para1.setAlignment(TextAlignmentType.CENTER);
tr1.getFill().setFillType(FillFormatType.SOLID);
tr1.getFill().getSolidColor().setColor(Color.blue);
shape.getTextFrame().getParagraphs().append(new ParagraphEx());
//在第一张幻灯片上添加形状
IAutoShape shape1 = presentation.getSlides().get(0).getShapes().appendShape(ShapeType.RECTANGLE, rec);
shape1.getFill().setFillType(FillFormatType.NONE);
shape1.getLine().setWidth(0);
//添加链接到网页的超链接
ParagraphEx para2 = new ParagraphEx();
PortionEx tr2 = new PortionEx();
tr2.setText("点击链接到网页");
tr2.getClickAction().setAddress("https://www.jianshu.com/");
para2.getTextRanges().append(tr2);
shape1.getTextFrame().getParagraphs().append(para2);
shape1.getTextFrame().getParagraphs().append(new ParagraphEx());
//添加链接到邮箱地址的超链接
ParagraphEx para3 = new ParagraphEx();
PortionEx tr3 = new PortionEx();
tr3.setText("点击链接到邮箱地址");
tr3.getClickAction().setAddress("mailto:Tina.tang@e-iceblue.com");
para3.getTextRanges().append(tr3);
shape1.getTextFrame().getParagraphs().append(para3);
shape1.getTextFrame().getParagraphs().append(new ParagraphEx());
//添加链接到其他文档的超链接
ParagraphEx para4 = new ParagraphEx();
PortionEx tr4 = new PortionEx();
tr4.setText("点击链接到其他文档");
tr4.getClickAction().setAddress("C:\\Users\\Test1\\Desktop\\月销售统计表.xlsx");
para4.getTextRanges().append(tr4);
shape1.getTextFrame().getParagraphs().append(para4);
shape1.getTextFrame().getParagraphs().append(new ParagraphEx());
//添加超链接跳转到其他幻灯片
ParagraphEx para5 = new ParagraphEx();
PortionEx tr5 = new PortionEx("点击跳转到第二张幻灯片");
ClickHyperlink link = new ClickHyperlink(presentation.getSlides().get(1));
tr5.setClickAction(link);
para5.getTextRanges().append(tr5);
shape1.getTextFrame().getParagraphs().append(para5);
//保存文档
presentation.saveToFile("output/TextHyperlink.pptx", FileFormat.PPTX_2010);
}
}
添加效果：
注：需幻灯片放映时方能显示超链接地址！
【示例2】添加图片超链接
import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;
import java.awt.geom.Rectangle2D;
public class ImageHyperlink {
public static void main(String[] args) throws Exception {
//创建Presentation对象
Presentation presentation = new Presentation();
//获取第一张幻灯片
ISlide slide = presentation.getSlides().get(0);
//添加图片到幻灯片
String imaPath = "C:\\Users\\Test1\\Desktop\\Signature.png";
Rectangle2D.Float rect = new Rectangle2D.Float(50, 50, 220, 100);
IEmbedImage image = slide.getShapes().appendEmbedImage(ShapeType.RECTANGLE, imaPath, rect);
//将图片形状的边线设置为无
image.getLine().setFillType(FillFormatType.NONE);
//添加超链接到图片
ClickHyperlink hyperlink = new ClickHyperlink("https://www.jianshu.com/u/96431825b792");
image.setClick(hyperlink);
//保存文档
presentation.saveToFile("output/ImageHyperLink.pptx", FileFormat.PPTX_2013);
}
}
