在下面给出的示例中，我们在演示文稿的第一张幻灯片中添加了一个矩形。

            
const asposeSlides = require('aspose.slides.via.net');

const { Presentation, SaveFormat, ShapeType } = asposeSlides;

var pres = new Presentation();
try
{
    var slide = pres.slides.get(0);
    slide.shapes.addAutoShape(ShapeType.Rectangle, 50, 150, 300, 200);

    pres.save("pres.pptx", SaveFormat.Pptx);
}
finally
{
    if (pres != null) pres.dispose();
}
