class="MsoNormal">本次内容介绍在C#程序中给PPT幻灯片添加Latex数学公式,添加公式前,首先需要在幻灯片中插入一个Shape形状,在形状的段落中通过方法 Paragraphs.AddParagraphFromLatexMathCode( string latexMathCode)写入公式,最后保存。
本次使用PPT库?Spire.Presentation for .NET Version 6.9.2,在VS程序中添加引用Spire.Presentation.dll。2种引用方法:
?
?
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
namespace AddFormula
{
class Program
{
static void Main(string[] args)
{
//新建一个PPT幻灯片文档,并获取第一张幻灯片(新建的幻灯片已默认包含一张幻灯片)
Presentation ppt = new Presentation();
ISlide slide = ppt.Slides[0];
//添加形状到幻灯片
IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(30, 100, 400, 30));
shape.Fill.FillType = FillFormatType.None;
shape.ShapeStyle.LineColor.Color = Color.White;
shape.TextFrame.Paragraphs.Clear();
//添加公式
string latexMathCode = @"$ f(x,y) = \sqrt[n]{{x^2}{y^3}} $";
shape.TextFrame.Paragraphs.AddParagraphFromLatexMathCode(latexMathCode);
//保存
ppt.SaveToFile("AddLatexMathCode.pptx", FileFormat.Pptx2013);
System.Diagnostics.Process.Start("AddLatexMathCode.pptx");
}
}
}
