使用java aspose库将html转换为ppt

我正在用java将html代码传递给一个变量。使用aspose库，应该执行html代码并将其呈现到ppt中（我还在html中引用css）。

---

如果ppt是可编辑的，我将不胜感激。

我已注意到您的要求，很抱歉与您分享。幻灯片是用于管理PowerPoint幻灯片的API，不支持将HTML转换为ppt/PPTX的功能。但是，它支持在幻灯片文本框中导入HTML文本，您可以使用这些文本框

// Create Empty presentation instance// Create Empty presentation instance
using (Presentation pres = new Presentation())
{
    // Acesss the default first slide of presentation
    ISlide slide = pres.Slides[0];

    // Adding the AutoShape to accomodate the HTML content
    IAutoShape ashape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 10, 10, pres.SlideSize.Size.Width - 20, pres.SlideSize.Size.Height - 10);

    ashape.FillFormat.FillType = FillType.NoFill;

    // Adding text frame to the shape
    ashape.AddTextFrame("");

    // Clearing all paragraphs in added text frame
    ashape.TextFrame.Paragraphs.Clear();

    // Loading the HTML file using stream reader
    TextReader tr = new StreamReader(dataDir + "file.html");

    // Adding text from HTML stream reader in text frame
    ashape.TextFrame.Paragraphs.AddFromHtml(tr.ReadToEnd());

    // Saving Presentation
    pres.Save("output_out.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
}

我注意到了您的评论，希望与大家分享导入HtmlTextInParagraphs.class指向文件路径的内容。我已经更新了与此相关的代码

其次，您需要在自己的位置调用import com.aspose.slides.IAutoShape来解决问题。
