PowerPoint中的母版保存了一些固定样式，例如背景图、标题、主题颜色等，能被其它幻灯片所继承。本文介绍如何使用Spire.Presentation for Java创建母版样式并应用到其他幻灯片。

创建唯一母版

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 CreateSlideMaster {

    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/Administrator/Desktop/bg.jpg";
        String logo = "C:/Users/Administrator/Desktop/logo.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(40,40,200,60));
        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("成都冰蓝科技有限公司");
        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();
    }
}

创建多个母版并分别应用到幻灯片

public class CreateMultiSlideMasters {

    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/Administrator/Desktop/image1.png";
        String pic2 = "C:/Users/Administrator/Desktop/image2.png";
        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("MultiSlideMaters.pptx", FileFormat.PPTX_2013);
        presentation.dispose();
    }
