Jar包引入

通过 Maven仓库下载导入，如下配置pom.xml：

<repositories>
    <repository>
        <id>com.e-iceblue</id>
        <url>https://repo.e-iceblue.cn/repository/maven-public/</url>
    </repository>
</repositories>
<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.presentation.jar </artifactId>
        <version>7.6.3</version>
    </dependency>
</dependencies>

如需手动导入，需要下载jar包到本地，然后解压，找到lib文件夹下的Spire.Presentation.jar文件。在IDEA中打开“Project Structure”界面，执行如图步骤将本地路径下的jar文件手动引入Java程序：

插入公式

下面是在PPT幻灯片中插入公式的主要方法和步骤：

创建Presentation类的对象，并通过Presentation.getSlides().get(int index)方法获取第一张幻灯片。
通过ISlide.getShapes().appendShape(ShapeType shapeType, Rectangle2D rectangle)方法添加形状到幻灯片。
通过IAutoShape.getTextFrame().getParagraphs().clear()方法删除形状中默认的段落后，通过IAutoShape.getTextFrame().getParagraphs().addParagraphFromLatexMathCode(String latexMathCode)方法添加公式到形状。LaTeX公式字符串可先行定义好，如本次代码示例。
最后，调用Presentation.saveToFile(String file, FileFormat fileFormat)方法保存文档到指定路径。

Java

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

import java.awt.geom.Rectangle2D;

public class AddFormula {
    public static void main(String[] args) throws Exception{
        //定义LaTeX公式代码
        String latexCode1 = "x^{2} + \\sqrt{x^{2}+1}=2";
        String latexCode2 = "F(x) &= \\int^a_b \frac{1}{3}x^3";
        String latexCode3 = "\\alpha + \\beta  \\geq \\gamma";
        String latexCode4 = "\\overrightarrow{abc}";
        String latexCode5 =" H_x=\\frac{1}{3}\\times{ \\left[ \\begin{array}{ccc}1 & 0 & -1\\\\1 & 0 & -1\\\\1 & 0 & -1\\end{array} \\right ]}";
        String latexCode6 = "\\log_a{b}";

        //创建Presentation类的实例
        Presentation ppt = new Presentation();

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

        //添加形状到幻灯片
        IAutoShape shape = slide.getShapes().appendShape(ShapeType.TRIANGLE, new Rectangle2D.Double(30, 100, 320, 50));
        shape.getTextFrame().getParagraphs().clear();
        //使用LaTeX代码添加数学公式到形状
        shape.getTextFrame().getParagraphs().addParagraphFromLatexMathCode(latexCode1);

        //重复以上操作，添加形状，并添加公式到形状
        shape = slide.getShapes().appendShape(ShapeType.TRIANGLE, new Rectangle2D.Double(280, 80, 380, 70));
        shape.getTextFrame().getParagraphs().clear();
        shape.getTextFrame().getParagraphs().addParagraphFromLatexMathCode(latexCode2);

        shape = slide.getShapes().appendShape(ShapeType.TRIANGLE, new Rectangle2D.Double(60, 190, 240, 40));
        shape.getTextFrame().getParagraphs().clear();
        shape.getTextFrame().getParagraphs().addParagraphFromLatexMathCode(latexCode3);

        shape = slide.getShapes().appendShape(ShapeType.TRIANGLE, new Rectangle2D.Double(350, 190, 200, 40));
        shape.getTextFrame().getParagraphs().clear();
        shape.getTextFrame().getParagraphs().addParagraphFromLatexMathCode(latexCode4);

        shape = slide.getShapes().appendShape(ShapeType.TRIANGLE, new Rectangle2D.Double(10, 240, 400, 100));
        shape.getTextFrame().getParagraphs().clear();
        shape.getTextFrame().getParagraphs().addParagraphFromLatexMathCode(latexCode5);

        shape = slide.getShapes().appendShape(ShapeType.TRIANGLE, new Rectangle2D.Double(350, 280, 200, 40));
        shape.getTextFrame().getParagraphs().clear();
        shape.getTextFrame().getParagraphs().addParagraphFromLatexMathCode(latexCode6);

        //设置形状边框和填充类型
        for (int i = 0; i < slide.getShapes().getCount(); i++)
        {
            slide.getShapes().get(i).getFill().setFillType(FillFormatType.NONE);
            slide.getShapes().get(i).getLine().setFillType(FillFormatType.NONE);
        }

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