Add a Paragraph to PowerPoint file

PPT file format is a vivid and explicit way to present your stuff. PPT file can be very beautiful and powerful. And text is a basic element that PPT supports. Spire.Presentation is a powerful .NET component specially designed for developers. It enables developers to manipulate PPT files easily and flexibly. In this document, I will introduce you how to add a paragraph to PPT file using Spire.Presentation.

Step 1. Create a PPT document.

Presentation presentation = new Presentation();

Step 2. Add a new shape to the document.

IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 70, 450, 150));
shape.Fill.FillType = FillFormatType.None;
shape.ShapeStyle.LineColor.Color = Color.White;

Shape represents a TextBox in PPT document.

Step 3. Add some text to the shape.

shape.TextFrame.Text = "This powerful component suite contains the most up-to-date versions of all .NET WPF Silverlight components offered by E-iceblue.";

These will form a new paragraph.

Step 4. Set the alignment of the paragraph.

shape.TextFrame.Paragraphs[0].Alignment = TextAlignmentType.Left;

Step 5. Set the indent of the paragraph.

shape.TextFrame.Paragraphs[0].Indent = 25*2;

Step 6. Set the line spacing of the paragraph.

shape.TextFrame.Paragraphs[0].LineSpacing = 250;

Step 7. Save the document.

presentation.SaveToFile("para.pptx", FileFormat.Pptx2010);

            //set background Image

            //set the linespacing
            shape.TextFrame.Paragraphs[0].LineSpacing = 150;
            shape.TextFrame.Text = "This powerful component suite contains the most up-to-date versions of all .NET WPF Silverlight components offered by E-iceblue.";

            //set the Font
            shape.TextFrame.Paragraphs[0].TextRanges[0].LatinFont = new TextFont("Arial Rounded MT Bold");
            shape.TextFrame.Paragraphs[0].TextRanges[0].Fill.FillType = FillFormatType.Solid;
            shape.TextFrame.Paragraphs[0].TextRanges[0].Fill.SolidColor.Color = Color.Black;

            //save the document
            presentation.SaveToFile("para.pptx", FileFormat.Pptx2010);
            System.Diagnostics.Process.Start("para.pptx");
