使用Java在 PPT 中的幻灯片上格式化文本

要使用Java在 PowerPoint 演示文稿中设置幻灯片上的文本格式，请使用名为 Apache POI 的Java库。 Apache POI 是 Apache Software Foundation 运行的一个项目，之前是 Jakarta Project 的一个子项目，提供纯Java库，用于读写 Microsoft Office 格式的文件，例如 Word、PowerPoint 和 Excel。使用 Apache 指南为 Windows/Linux 系统安装 Apache POI 库。

方法：

1. 使用 Apache POI包中的XMLSlideShow创建一个空的 Presentation Object。
2. 创建 SlideMaster 对象并使用XSLFSlideMaster获取第一张幻灯片。
3. 使用XSLFSlideLayout对象设置幻灯片的布局。
4. 使用布局创建幻灯片。
5. 使用XSLFTextShape对象获取 Slide 的第二个标题，并使用XSLFTextParagraph对象向其中添加 Paragraph。
6. 使用XSLFTextRun对象向段落添加行并添加格式属性。

执行：

Java

// Formatting text on a slide in a PPT using java
import java.io.*;
  
// importing Apache POI environment packages
import org.apache.poi.xslf.usermodel.*;
  
public class FormatTextPPT {
    public static void main(String args[])
        throws IOException
    {
  
        // creating an empty presentation
        XMLSlideShow ppt = new XMLSlideShow();
  
        // creating the slide master object
        XSLFSlideMaster slideMaster
            = ppt.getSlideMasters().get(0);
  
        // select a layout from specified slideLayout list
        XSLFSlideLayout slidelayout = slideMaster.getLayout(
            SlideLayout.TITLE_AND_CONTENT);
  
        // creating a slide with title and content layout
        XSLFSlide slide = ppt.createSlide(slidelayout);
  
        // selection of title place holder
        XSLFTextShape title = slide.getPlaceholder(1);
        
        // clear the existing text in the slide
        title.clearText();
  
        // adding new paragraph
        XSLFTextParagraph paragraph
            = title.addNewTextParagraph();
  
        // formatting line 1
        XSLFTextRun line1 = paragraph.addNewTextRun();
        line1.setText("Formatted Bold");
        
        // making the text bold
        line1.setBold(true);
        
        // moving to the next line
        paragraph.addLineBreak();
  
        // formatting line 2
        XSLFTextRun line2 = paragraph.addNewTextRun();
        line2.setText("Formatted with Color");
        
        // setting color to the text
        line2.setFontColor(java.awt.Color.RED);
        
        // setting font size to the text
        line2.setFontSize(24.0);
        
        // moving to the next line
        paragraph.addLineBreak();
  
        // formatting line 3
        XSLFTextRun line3 = paragraph.addNewTextRun();
        line3.setText("Formatted with Underline");
        
        // underlining the text
        line3.setUnderlined(true);
        
        // setting color to the text
        line3.setFontColor(java.awt.Color.GRAY);
        
        // moving to the next line
        paragraph.addLineBreak();
  
        // formatting line 4
        XSLFTextRun line4 = paragraph.addNewTextRun();
        line4.setText("Text Formatted with Strike");
        line4.setFontSize(12.0);
        
        // making the text italic
        line4.setItalic(true);
        
        // setting color to the text
        line4.setFontColor(java.awt.Color.BLUE);
        
        // strike through the text
        line4.setStrikethrough(true);
        
        // setting font size to the text
        line4.setFontSize(24.0);
        
        // moving to the next line
        paragraph.addLineBreak();
  
        // getting path of current working directory
        // to create the pdf file in the same directory of
        // the running java program
        String path = System.getProperty("user.dir");
        path += "/FormattedText.pptx";
  
        // creating a file object with the path specified
        File file = new File(path);
        FileOutputStream out = new FileOutputStream(file);
  
        // saving the changes to a file
        ppt.write(out);
        out.close();
        ppt.close();
        System.out.println(
            "PPT with Formatted Text created successfully!");
    }
}

程序执行后：

输出：FormattedText.ppt
