如何使用 OpenXml 在演示文档中应用边距

Question

I wrote code to create Presentation Document using open-xml SDK. I follow this sample code. MSDD Sample Code . Now i need to apply margin before starting my text. I've tried below code but didn't get expected result.

slidePart1.Slide = new Slide(
                new CommonSlideData(
                    new ShapeTree(
                        new P.NonVisualGroupShapeProperties(
                            new P.NonVisualDrawingProperties() { Id = (UInt32Value)1U, Name = "" },
                            new P.NonVisualGroupShapeDrawingProperties(),
                            new ApplicationNonVisualDrawingProperties()),
                        new GroupShapeProperties(new A.TransformGroup()),
                        new P.Shape(
                            new P.NonVisualShapeProperties(
                                new P.NonVisualDrawingProperties() { Id = (UInt32Value)2U, Name = "Title 1" },
                                new P.NonVisualShapeDrawingProperties(new D.ShapeLocks() { NoGrouping = true }),
                                new ApplicationNonVisualDrawingProperties(new PlaceholderShape())),
                            new P.ShapeProperties(),
                            new P.TextBody(
                                new D.BodyProperties(),
                                new D.ListStyle(),
                                new A.Paragraph(new D.EndParagraphRunProperties() { Language = "en-US" }, new D.ParagraphProperties() { LeftMargin = 10 }),
                                //new A.Paragraph(new A.Run(new A.RunProperties() { Bold = true, Italic = true, Underline = D.TextUnderlineValues.Single }, new A.Text()
                                //{ Text = text })))))),
                                new A.Paragraph(textListWithStyle.ToArray()))))),
                new ColorMapOverride(new D.MasterColorMapping()));

My generated PPT File looks like:

No left margin applied but in code i applied 10 left margin.

It seems not so easy to add an indented paragraph using Open XML SDK. With Aspose.Slides for .NET , this can be done like this:

// Create a new presentation.
using var presentation = new Presentation();

// Add a text box to the first slide.
var slide = presentation.Slides[0];
var rectangle = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 20, 20, 200, 150);

// Create a new paragraph.
var paragraph = new Paragraph();
paragraph.Text = "Some text.";

// Set left margin for the paragraph.
paragraph.ParagraphFormat.MarginLeft = 10;

// Add the paragraph to the text box.
rectangle.TextFrame.Paragraphs.Add(paragraph);

// Save the presentation to PPTX format.
presentation.Save("example.pptx", SaveFormat.Pptx);

This is a paid product, but you can get a temporary license to evaluate all features of this library. I work as a Support Developer at Aspose.
