Spire.Presentation 支持将HTML格式的文本插入到PowerPoint幻灯片中。html

代码演示：ide

Step 1:建立Presentation类的实例。orm

Presentation ppt = new Presentation();

Step 2:在幻灯片中插入一个自动形状（矩形）。htm

IAutoShape shape = ppt.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 50, 400, 100));

Step 3:清除形状中的默认段落。blog

shape.TextFrame.Paragraphs.Clear();

Step 4:从HTML代码添加段落形状，确保您的HTML片断是在和标签之间编写的，不然AddFromHtml方法将没法正常工做。图片

string htmlText= "<html><body><p>First paragraph</p><p>Second paragraph</p></body></html>";
shape.TextFrame.Paragraphs.AddFromHtml(htmlText);

Step 5:保存至档案。get

ppt.SaveToFile("output.pptx", FileFormat.Pptx2013);

输出：string

完整代码：io
