前言

在PowerPoint文档中，幻灯片母版可供用户设置幻灯片的样式，比如标题文字、背景、属性等。预先设定好的幻灯片母版可用于所有幻灯片，此外，也可创建多个幻灯片母版分别应用到幻灯片中。本文将介绍如何创建并应用单个或多个幻灯片母版。

环境构建

文中演示代码用到的工具是Free Spire.Presentation for Java，可通过官网下载获取。解压后将位于lib文件夹下的Spire.Presentation.jar导入Java程序。此外，还可通过maven仓库安装导入。

Java代码示例

示例1 创建唯一母版，并应用于所有幻灯片

import com.spire.presentation.*;
import com.spire.presentation.drawing.BackgroundType;
import com.spire.presentation.drawing.FillFormatType;
import com.spire.presentation.drawing.IImageData;
import com.spire.presentation.drawing.PictureFillType;
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.geom.Rectangle2D;
import java.awt.image.BufferedImage;
import java.io.FileInputStream;

public class UniqueSlideMaster {
  public static void main(String[] args) throws Exception {

    //创建PPT文档，指定幻灯片大小
    Presentation presentation = new Presentation();
    presentation.getSlideSize().setType(SlideSizeType.SCREEN_16_X_9);

    //获取第一张母版
    IMasterSlide masterSlide = presentation.getMasters().get(0);

    //获取图片地址
    String backgroundPic = "C:\\Users\\Test1\\Desktop\\Background.jpg";
    String logo = "C:\\Users\\Test1\\Desktop\\logo2.png";

    //设置母版背景
    BufferedImage image = ImageIO.read(new FileInputStream(backgroundPic));
    IImageData imageData = presentation.getImages().append(image);
    masterSlide.getSlideBackground().setType(BackgroundType.CUSTOM);
    masterSlide.getSlideBackground().getFill().setFillType(FillFormatType.PICTURE);
    masterSlide.getSlideBackground().getFill().getPictureFill().setFillType(PictureFillType.STRETCH);
    masterSlide.getSlideBackground().getFill().getPictureFill().getPicture().setEmbedImage(imageData);

    //添加图片（公司Logo）到母版
    image = ImageIO.read(new FileInputStream(logo));
    imageData = presentation.getImages().append(image);
    IEmbedImage imageShape = masterSlide.getShapes().appendEmbedImage(ShapeType.RECTANGLE,imageData,new Rectangle2D.Float(40,40,200,100));
    imageShape.getLine().setFillType(FillFormatType.NONE);

    //添加文字（公司名称）到母版
    IAutoShape textShape = masterSlide.getShapes().appendShape(ShapeType.RECTANGLE, new Rectangle2D.Float((float) presentation.getSlideSize().getSize().getWidth()-200,(float) presentation.getSlideSize().getSize().getHeight()-60,200,30));//Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(ppt.SlideSize.Size.Width-200, ppt.SlideSize.Size.Height-60, 200, 30));
    textShape.getTextFrame().setText("鹰翔传媒有限公司");
    textShape.getTextFrame().getTextRange().setFontHeight(15f);
    textShape.getTextFrame().getTextRange().getFill().setFillType(FillFormatType.SOLID);
    textShape.getTextFrame().getTextRange().getFill().getSolidColor().setColor(Color.blue);
    textShape.getTextFrame().getTextRange().getParagraph().setAlignment(TextAlignmentType.CENTER);
    textShape.getFill().setFillType(FillFormatType.NONE);
    textShape.getLine().setFillType(FillFormatType.NONE);

    //添加一张幻灯片
    presentation.getSlides().append();

    //保存文档
    presentation.saveToFile("output/SlideMaster.pptx", FileFormat.PPTX_2013);
    presentation.dispose();
  }
}

示例2 创建多个母版并分别应用到幻灯片

import com.spire.presentation.*;
import com.spire.presentation.drawing.BackgroundType;
import com.spire.presentation.drawing.FillFormatType;
import com.spire.presentation.drawing.IImageData;
import com.spire.presentation.drawing.PictureFillType;

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.FileInputStream;
public class MultiSlideMasters {
  public static void main(String[] args)throws Exception {
    //新建PPT文档
    Presentation presentation = new Presentation();
    presentation.getSlideSize().setType(SlideSizeType.SCREEN_16_X_9);

    //插入4页幻灯片(连同默认的幻灯片，文档中共5页)
    for (int i = 0; i < 4; i++)
    {
      presentation.getSlides().append();
    }

    //获取默认的母版
    IMasterSlide first_master = presentation.getMasters().get(0);

    //创建并获取第二个母板
    presentation.getMasters().appendSlide(first_master);
    IMasterSlide second_master = presentation.getMasters().get(1);

    //为两个母版分别设置不同的背景图片
    String pic1 = "C:\\Users\\Test1\\Desktop\\Image1.jpg";
    String pic2 = "C:\\Users\\Test1\\Desktop\\Image2.jpg";
    BufferedImage image = ImageIO.read(new FileInputStream(pic1));
    IImageData imageData = presentation.getImages().append(image);
    first_master.getSlideBackground().setType(BackgroundType.CUSTOM);
    first_master.getSlideBackground().getFill().setFillType(FillFormatType.PICTURE);
    first_master.getSlideBackground().getFill().getPictureFill().setFillType(PictureFillType.STRETCH);
    first_master.getSlideBackground().getFill().getPictureFill().getPicture().setEmbedImage(imageData);
    image = ImageIO.read(new FileInputStream(pic2));
    imageData = presentation.getImages().append(image);
    second_master.getSlideBackground().setType(BackgroundType.CUSTOM);
    second_master.getSlideBackground().getFill().setFillType(FillFormatType.PICTURE);
    second_master.getSlideBackground().getFill().getPictureFill().setFillType(PictureFillType.STRETCH);
    second_master.getSlideBackground().getFill().getPictureFill().getPicture().setEmbedImage(imageData);

    //在第一页应用第一个母版及版式（板式6为空板式）
    presentation.getSlides().get(0).setLayout(first_master.getLayouts().get(6));

    //在剩下的幻灯片应用第二个母版及版式
    for (int i = 1; i < presentation.getSlides().getCount(); i++)
    {
      presentation.getSlides().get(i).setLayout(second_master.getLayouts().get(6));
    }

    //保存文档
    presentation.saveToFile("output/MultiSlideMaters.pptx", FileFormat.PPTX_2013);
    presentation.dispose();
  }
}
