3-D is the abbreviation for three-dimensional. After adding a shape into the slide, we could set its format as 3-D, which looks more fresh and attractive. We could use options like Bevel, Contours, and Surface Material to customize 3-D shapes. This article is going to introduce the method to set 3-D shapes in C# using Spire.Presentation.
Note: before start, please download the latest version of Spire.Presentation and add the .dll in the bin folder as the reference of Visual Studio.
Step 1: Create a new presentation document.
Presentation presentation = new Presentation();
Step 2: Add shape1 and fill it with color.
IAutoShape shape1 = presentation.Slides[0].Shapes.AppendShape(ShapeType.RoundCornerRectangle, new RectangleF(150, 150, 150, 150)); shape1.Fill.FillType = FillFormatType.Solid; shape1.Fill.SolidColor.KnownColor = KnownColors.RoyalBlue;
Step 3: Initialize a new instance of the 3-D class for shape1 and set its properties.
ShapeThreeD Demo1 = shape1.ThreeD.ShapeThreeD;
Demo1.PresetMaterial = PresetMaterialType.Powder;
Demo1.TopBevel.PresetType = BevelPresetType.ArtDeco;
Demo1.TopBevel.Height = 4;
Demo1.TopBevel.Width = 12;
Demo1.BevelColorMode = BevelColorType.Contour;
Demo1.ContourColor.KnownColor = KnownColors.LightBlue;
Demo1.ContourWidth = 3.5;
Step 4: Set 3-D format for shape2 as comparison.
IAutoShape shape2 = presentation.Slides[0].Shapes.AppendShape(ShapeType.Pentagon, new RectangleF(400, 150, 150, 150));
shape2.Fill.FillType = FillFormatType.Solid;
shape2.Fill.SolidColor.KnownColor = KnownColors.LawnGreen;
ShapeThreeD Demo2 = shape2.ThreeD.ShapeThreeD;
Demo2.PresetMaterial = PresetMaterialType.SoftEdge;
Demo2.TopBevel.PresetType = BevelPresetType.SoftRound;
Demo2.TopBevel.Height = 12;
Demo2.TopBevel.Width = 12;
Demo2.BevelColorMode = BevelColorType.Contour;
Demo2.ContourColor.KnownColor = KnownColors.LawnGreen;
Demo2.ContourWidth = 5;
Step 5: Save the document and launch to see effects.
presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");

RTF (Rich Text Format) is a cross-platform document developed by Microsoft in the 1980s. RTF can be opened by most word processors, and it is also convenient for editing. But when it comes to sharing and printing documents in daily work, it’s more recommended to convert the RTF to PDF for further processing. In this article, you will learn how to convert RTF to PDF programmatically using Spire.Doc for .NET.
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for .NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Doc
Convert RTF to PDF in C# and VB.NET
Spire.Doc for .NET enables you to directly load a file with .rtf extension and then convert it to PDF with only three lines of code. The detailed steps are as follows.
- Create a Document instance.
- Load a sample RTF document using Document.LoadFromFile() method.
- Save the document as a PDF file using Document.SaveToFile() method.

After finishing designs of shapes in slides, accidental changes might happen if we haven't made necessary protecting settings. Locking shapes from being selected firstly or preventing changes to shape attributes (like size, position, rotation etc.) can be used to prevent changes to shapes. It's necessary to mention that Spire.Presentation supports the features to prevent changes to shapes. This article is going to introduce how to prevent or allow changes to shapes in C# using Spire.Presentation.
Note: before start, please download the latest version of Spire.Presentation and add the .dll in the bin folder as the reference of Visual Studio.
Step 1: create a presentation file and add a sample shape.
Presentation presentation = new Presentation();
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 100, 450, 150));
Step 2: format the sample shape.
shape.Fill.FillType = FillFormatType.None;
shape.ShapeStyle.LineColor.Color = Color.DarkGreen;
shape.TextFrame.Paragraphs[0].Alignment = TextAlignmentType.Justify;
shape.TextFrame.Text = "Demo for locking shapes:\n Green/Black stands for editable.\n Grey points stands for non-editable.";
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;
Step 3: set which operations are disabled on the shape to prevent changes. Here the selection and rotation changing of the shape are allowed while the changes of size, position, shape type, text, rotation, handles, and aspect ratio are not allowed.
shape.Locking.RotationProtection = false;
shape.Locking.SelectionProtection = false;
shape.Locking.ResizeProtection = true;
shape.Locking.PositionProtection = true;
shape.Locking.ShapeTypeProtection = true;
shape.Locking.AspectRatioProtection = true;
shape.Locking.TextEditingProtection = true;
shape.Locking.AdjustHandlesProtection = true;

In the class of DocOleObject, a method named AppendOleObject(Stream oleStream, DocPicture olePicture, string fileExtension) is available for users to insert media file with the extension of mp3, mp4, avi or any other format into a Word document. The three parameters in this method represent:
- oleStream: The OLE file stream.
- olePicture: The image (icon) that is displayed in Word to show the OLE object.
- fileExtension: The file extension.
Code Snippet:
Step 1: Initialize a new instance of Document class and add a new section.
Document doc = new Document(); Section section = doc.AddSection();
Step 2: Add a new paragraph, append some formatted text into the paragraph.
Paragraph para1 = section.AddParagraph();
para1.AppendText("Double click the PLAY button to view the video file");
ParagraphStyle style1 = new ParagraphStyle(doc);
style1.Name = "Style";
style1.CharacterFormat.FontName = "Calibri";
style1.CharacterFormat.FontSize = 15;
style1.CharacterFormat.Bold = true;
style1.CharacterFormat.TextColor = Color.Red;
doc.Styles.Add(style1);

How to Mark a Presentation as Final using Spire.Presentation in C#, VB.NET
2015-08-06 05:54:52 Written by KoohjiThe Mark as Final command makes a presentation read-only and prevents changes to the document. When you share a presentation that is marked as final, you're telling viewers the presentation is final and no changes on it are wanted. In this article, I'll make a brief introduction about how to mark a presentation as final using Spire.Presentation in C#, VB.NET.
In Spire.Presentation, the presentation class contains a property of DocumentProperty which enables developers to set document properties easily. Here in this case, you are able to mark a presentation as final by setting the Boolean value of MarkAsFinal as true.
Code Snippet:
Step 1: Initialize a new instance of presentation class and load the sample file.
Presentation ppt = new Presentation();
ppt.LoadFromFile("sample.pptx",FileFormat.Pptx2010);
Step 2: Set the value of MarkAsFinal property as true.
ppt.DocumentProperty["_MarkAsFinal"] =true;
Step 3: Save and launch the file.
ppt.SaveToFile("result.pptx",FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");

Inserting paragraphs in Word is a fundamental skill for creating well-structured and organized documents. Paragraphs can break down large blocks of text, making it easier for readers to follow the flow of ideas and find specific information. In Word, you can add new paragraphs to represent new ideas or add additional information. This article will demonstrate how to insert a new paragraph in Word in C# using Spire.Doc for .NET.
- Add a Paragraph at the End of a Word Document in C#
- Insert a Paragraph at a Specified Location in Word in C#
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for .NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Doc
Add a Paragraph at the End of a Word Document in C#
To add a new paragraph at the end, you need to get the last section of the Word document through the Document.LastSection property, and then add a paragraph at the end of the section through the Section.AddParagraph() method. The following are the detailed steps:
- Create a Document instance.
- Load a Word document using Document.LoadFromFile() method.
- Get the last section of the document using Document.LastSection property.
- Add a paragraph at the end of the section using Section.AddParagraph() method, and then add text to it using Paragraph.AppendText() method.
- Create a ParagraphStyle object and set the font name, size, style of the paragraph text.
- Apply the paragraph style using Paragraph.ApplyStyle() method
- Save the result document using Document.SaveToFile() method.
- C#
using Spire.Doc;
using Spire.Doc.Documents;
using System.Drawing;
namespace AddParagraph
{
class Program
{
static void Main(string[] args)
{
//Create a Document object
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("Test.docx");
//Get the last section
Section section = doc.LastSection;
//Add a paragraph at the end and set its text content
Paragraph para = section.AddParagraph();
para.AppendText("Add a paragraph to the end of the document.");
//Set the paragraph style
ParagraphStyle style = new ParagraphStyle(doc);
style.Name = "Style1";
style.CharacterFormat.FontName = "Times New Roman";
style.CharacterFormat.FontSize = 12;
style.CharacterFormat.TextColor = Color.Blue;
style.CharacterFormat.Bold = true;
doc.Styles.Add(style);
para.ApplyStyle("Style1");
para.Format.BeforeSpacing = 10;
//Save the result file
doc.SaveToFile("AddParagraph.docx", FileFormat.Docx2016);
}
}
}
Insert a Paragraph at a Specified Location in Word in C#
You can also add a paragraph and then insert it to a specified position through the Section.Paragraphs.Insert(int index, IParagraph paragraph) method. The following are the detailed steps:
- Create a Document instance.
- Load a Word document using Document.LoadFromFile() method.
- Get a specified section using Document.Sections[] property.
- Add a paragraph using Section.AddParagraph() method, and then add text to it using Paragraph.AppendText() method.
- Set the font name, size, style of the paragraph text.
- Insert the newly added paragraph at a specified index using Section.Paragraphs.Insert(int index, IParagraph paragraph) method.
- Save the result document using Document.SaveToFile() method.
- C#
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;
namespace InsertParagraph
{
class Program
{
static void Main(string[] args)
{
//Create a Document object
Document doc = new Document();
//Load a Word document
doc.LoadFromFile("Test.docx");
//Get the first section
Section section = doc.Sections[0];
//Add a paragraph and set its text content
Paragraph para = section.AddParagraph();
TextRange textRange = para.AppendText("Insert a paragraph at a specified location in the Word document.");
//Set the font name, size, color and style
textRange.CharacterFormat.TextColor = Color.Blue;
textRange.CharacterFormat.FontName = "Times New Roman";
textRange.CharacterFormat.FontSize = 14;
textRange.CharacterFormat.UnderlineStyle = UnderlineStyle.Single;
//Insert the paragraph as the third paragraph
section.Paragraphs.Insert(2, para);
//Set spacing after the paragraph
para.Format.AfterSpacing = 10;
//Save the result file
doc.SaveToFile("InsertParagraph.docx", FileFormat.Docx2016);
}

In order to distinguish nested bookmarks more clearly, you can set different font style and font color for parent and child bookmarks respectively. In this article, I’ll introduce how to modify bookmarks in the terms of font style, font color and text using Spire.PDF in C#, VB.NET.
Main Steps:
Step 1: Initialize a new object of PdfDocument and load the existing PDF file.
PdfDocument doc = new PdfDocument("Bookmark.Pdf");
Step 2: Get all bookmarks from the test file.
PdfBookmarkCollection bookmarks = doc.Bookmarks;
Step 3: Traverse very first-level bookmark in the bookmark tree. Change the properties of selected or all bookmarks, including title, color and display style.
foreach (PdfBookmark parentBookmark in bookmarks)
{
//change "Word Bookmarks" to "M BookMark"
bookmarks[0].Title = "Modified BookMarks";
//set the color of the bookmark
parentBookmark.Color = Color.Black;
parentBookmark.DisplayStyle = PdfTextStyle.Bold;
//edit child bookmark of parent bookmark
EditChildBookmark(parentBookmark);
}
Step 4: In step 3, there is a nested method predefined as below. By invoking this method, we are able to modify child bookmarks of the upper level bookmark. In this example, we have two nested level bookmarks under the first-level bookmark.
static void EditChildBookmark(PdfBookmark parentBookmark)
{
foreach (PdfBookmark childBookmark in parentBookmark)
{
childBookmark.Color = Color.Brown;
childBookmark.DisplayStyle = PdfTextStyle.Regular;
EditChild2Bookmark(childBookmark);
}
}
static void EditChild2Bookmark(PdfBookmark childBookmark)
{
foreach (PdfBookmark child2Bookmark in childBookmark)
{
child2Bookmark.Color = Color.LightSalmon;
child2Bookmark.DisplayStyle = PdfTextStyle.Italic;
}
}
Step 5: Save and launch the file.
doc.SaveToFile("Result.Pdf");
System.Diagnostics.Process.Start("Result.Pdf");

With Spire.Presentation for .NET, developers can add different shapes to slides in C#. We can also use Spire.Presentation to formatting the lines of shape, such as the style, width, dash style and color of the line, etc. This article will show you how to set the format for the shape lines in C#. We will use rectangle for example. Here comes to the code snippet:
Step 1: Create a PPT document.
Presentation presentation = new Presentation();
Step 2: Add a rectangle shape to the slide.
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 100, 100, 100));
Step 3: Set the fill color of the rectangle shape.
shape.Fill.FillType = FillFormatType.Solid; shape.Fill.SolidColor.Color = Color.White;
Step 4: Apply some formatting on the line of the rectangle.
shape.Line.Style = TextLineStyle.ThickThin; shape.Line.Width = 5; shape.Line.DashStyle = LineDashStyleType.Dash;
Step 5: Set the color of the line of the rectangle.
shape.ShapeStyle.LineColor.Color = Color.Red;
Step 6: Save the document to file.
presentation.SaveToFile("shape.pptx", FileFormat.Pptx2010);
