本文将介绍如何使用Spire.Presentation for Java在PowerPoint幻灯片中创建编号列表和项目符号列表。

创建编号列表

import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;

import java.awt.*;
import java.awt.geom.Rectangle2D;

public class NumberedBullets {
    public static void main(String[] args) throws Exception {
        //创建Presentation实例
        Presentation ppt = new Presentation();

        //获取第一张幻灯片
        ISlide slide = ppt.getSlides().get(0);

        Rectangle2D rect = new Rectangle2D.Double(50, 70, 300, 200);
        //添加一个形状到幻灯片
        IAutoShape shape = slide.getShapes().appendShape(ShapeType.RECTANGLE, rect);
        shape.getShapeStyle().getLineColor().setColor(Color.white);
        shape.getFill().setFillType(FillFormatType.NONE);

        //移除形状中的默认段落
        shape.getTextFrame().getParagraphs().clear();

        String[] str = new String[] {"Item 1", "Item 2", "Item 3"};

        //添加段落并设置列表格式为编号列表
        for(int i = 0; i < str.length; i ++)
        {
            ParagraphEx paragraph = new ParagraphEx();
            paragraph.setText(str[i]);
            paragraph.getTextRanges().get(0).getFill().setFillType(FillFormatType.SOLID);
            paragraph.getTextRanges().get(0).getFill().getSolidColor().setColor(Color.black);
            paragraph.setBulletType(TextBulletType.NUMBERED);
            paragraph.setBulletStyle(NumberedBulletStyle.BULLET_ROMAN_LC_PERIOD);
            shape.getTextFrame().getParagraphs().append(paragraph);
        }

        //保存文档
        ppt.saveToFile("NumberedBullets.pptx", FileFormat.PPTX_2013);
    }
}

添加项目符号列表

import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;

import java.awt.*;
import java.awt.geom.Rectangle2D;

public class SymbolBullets {
    public static void main(String[] args) throws Exception {
        //创建Presentation实例
        Presentation ppt = new Presentation();

        //获取第一张幻灯片
        ISlide slide = ppt.getSlides().get(0);

        Rectangle2D rect = new Rectangle2D.Double(50, 70, 300, 200);
        //添加一个形状到幻灯片
        IAutoShape shape = slide.getShapes().appendShape(ShapeType.RECTANGLE, rect);
        shape.getShapeStyle().getLineColor().setColor(Color.white);
        shape.getFill().setFillType(FillFormatType.NONE);

        //清除形状中的默认段落
        shape.getTextFrame().getParagraphs().clear();

        String[] str = new String[] {"Item 1", "Item 2", "Item 3"};

        //添加段落到形状并设置列表格式为项目符号
        for(int i = 0; i < str.length; i ++)
        {
            ParagraphEx paragraph = new ParagraphEx();
            paragraph.setText(str[i]);
            paragraph.getTextRanges().get(0).getFill().setFillType(FillFormatType.SOLID);
            paragraph.getTextRanges().get(0).getFill().getSolidColor().setColor(Color.black);
            paragraph.setBulletType(TextBulletType.SYMBOL);
            shape.getTextFrame().getParagraphs().append(paragraph);
        }

        //保存文档
        ppt.saveToFile("SymbolBullets.pptx", FileFormat.PPTX_2013);
    }
}
