net core 将 ppt文件 转 图片文件

您可以使用Aspose.Slides for .NET来将PPT文件转换为图像文件。以下是一个示例代码：

using Aspose.Slides.Export;

// Load the PPT file
using (var presentation = new Presentation("Presentation.ppt"))
{
    // Define the image options
    var imageOptions = new ImageOptions
    {
        Format = ImageFormat.Png,
        Quality = 100
    };

    // Export each slide as a separate image file
    for (int i = 0; i < presentation.Slides.Count; i++)
    {
        using (var imageStream = new MemoryStream())
        {
            // Save the slide as an image
            presentation.Slides[i].Save(imageStream, SlideExportFormat.Png, imageOptions);

            // Save the image file
            using (var fileStream = new FileStream($"Slide{i + 1}.png", FileMode.Create))
            {
                imageStream.WriteTo(fileStream);
            }
        }
    }
}

此代码将在当前目录下创建一个名为 "Slide1.png"、"Slide2.png" 等的图像文件，对应于PPT文件中的每个幻灯片。您可以根据需要更改图像格式、质量和输出路径
