owerPoint幻灯片中可插入公式,用于在幻灯片放映时演示相关内容的论证、推算的依据,能有效地为演讲者提供论述的数据支撑。通过后端程序代码,我们可借助特定的工具来实现在幻灯片中的插入公式,本文,将对此作详细介绍。
通过 Maven仓库 下载导入,如下配置pom.xml:
- 复制代码

spire.presentation.jar -
7.6.3 -
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:
下面是在PPT幻灯片中插入公式的主要方法和步骤:
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();
- }
- }
