PPT file format is commonly used for office and educational slide shows. With Spire.Presentation, you can generate beautiful and powerful PPT files and edit them without utilizing Microsoft PowerPoint. The PPT files generated are compatible with PowerPoint.
In this document, I will introduce you how to set Font of text in PPT file. First add IAutoShape to the slide. The IAutoShape is a TextBox. You have to add it first. Then add text to the IAutoShape using the method AppendTextFrame. Then you can get the property TextRange of the shape. Using TextRange, you can set Font of text finally.
Step 1: Add the shape to the slide.
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle,
new RectangleF(50, 70, 400, 50));
Step 2: Add the text to the shape.
shape.AppendTextFrame("This is a demo of text font and color.");
Step 3: Get the property TextRange of the text.
TextRange textRange = shape.TextFrame.TextRange;
Step 4: Set the Font of the text in shape.
textRange.FontHeight = 21;
textRange.IsItalic = TriState.True;
textRange.TextUnderlineType = TextUnderlineType.Single;
textRange.LatinFont = new TextFont("Gulim");
Step 5: Save the document.
presentation.SaveToFile("text.pptx", FileFormat.Pptx2007);
Full code:
using Spire.Presentation;
using System.Drawing;
namespace SetFont
{
class Program
{
static void Main(string[] args)
{
//create PPT document
Presentation presentation = new Presentation();
//set background Image
string ImageFile = @"..\..\..\..\..\..\Data\bg.png";
RectangleF rect = new RectangleF(0, 0, presentation.SlideSize.Size.Width, presentation.SlideSize.Size.Height);
presentation.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, ImageFile, rect);
presentation.Slides[0].Shapes[0].Line.FillFormat.SolidFillColor.Color = Color.FloralWhite;
//append new shape
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle,
new RectangleF(50, 70, 400, 50));
//set the LineColor
shape.ShapeStyle.LineColor.Color = Color.Black;
//set the color and fill style
shape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.Solid;
shape.Fill.SolidColor.Color = Color.LightGray;
shape.AppendTextFrame("This is a demo of text font and color.");
//set the color of text in shape
TextRange textRange = shape.TextFrame.TextRange;
textRange.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.Solid;
textRange.Fill.SolidColor.Color = Color.Green;
//set the Font of text in shape
textRange.FontHeight = 21;
textRange.IsItalic = TriState.True;
textRange.TextUnderlineType = TextUnderlineType.Single;
textRange.LatinFont = new TextFont("Gulim");
//save the document
presentation.SaveToFile("text.pptx", FileFormat.Pptx2007);
System.Diagnostics.Process.Start("text.pptx");
}
}
}
Screenshot:
PPT text Alignment can be taken as one kind of text format tools. It allows users to align text with the following styles: Left, Right, Center and Justify. By default, text will be aligned right. Also, users can customize alignment. Below demonstrate the effect by a screenshot which shows the text is corresponding to the alignment, for example, text Left is aligned left and Center is aligned center.
Spire.Presentation for .NET, a professional .NET PPT component to allow users to manipulate PPT documents without automation. This guide will introduce a method to align text with C#, VB.NET via Spire.Presentation for .NET.
The method is:
First, new a PPT document, and set its slide. Then, traversal all alignment and use the new paragraph to show them. Last set the font and fill style for added paragraphs.
Download and install Spire.Presentation for .NET and use below code to experience this method to align text in PPT document.
The full code:
using System;
using System.Drawing;
using Spire.Presentation;
using Spire.Presentation.Drawing;
namespace Alignment
{
class Program
{
static void Main(string[] args)
{
Presentation presentation = new Presentation();
//set background Image
string ImageFile = @"bg.png";
// set the rectangle size and position
RectangleF rect = new RectangleF(0, 0, presentation.SlideSize.Size.Width, presentation.SlideSize.Size.Height);
//set the slide's shapes,background image and rectangle .
presentation.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, ImageFile, rect);
//set the shape's solidFillColor
presentation.Slides[0].Shapes[0].Line.FillFormat.SolidFillColor.Color = Color.FloralWhite;
//append new shape
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 70, 600, 400));
shape.TextFrame.Paragraphs[0].Alignment = TextAlignmentType.Left;
shape.Fill.FillType = FillFormatType.None;
shape.TextFrame.Text = "Demo about Alignment";
foreach (TextAlignmentType textAlign in Enum.GetValues(typeof(TextAlignmentType)))
{
//create a text range
TextRange textRange = new TextRange(textAlign.ToString());
//create a new paragraph
TextParagraph paragraph = new TextParagraph();
//apend the text range
paragraph.TextRanges.Append(textRange);
//set the alignment
paragraph.Alignment = textAlign;
//append to shape
shape.TextFrame.Paragraphs.Append(paragraph);
}
//set the font and fill style
foreach (TextParagraph paragraph in shape.TextFrame.Paragraphs)
{
paragraph.TextRanges[0].LatinFont = new TextFont("Arial Black");
paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
paragraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;
}
//save the document
presentation.SaveToFile("alignment.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("alignment.pptx");

In this document, we will quickly help you finish a simple demo about Spire.Presentation using Visual Studio. As usual, it's a HelloWorld demo. Before you get started, please make sure the Spire.Presentation and Visual Studio (2005 or later) are installed on your computer.
1. In Visual Studio, click, File, New, and then Project. If you want to create a C# project, select Visual C#, Windows and choose Windows Forms Application and name the project HelloWorld. Click OK. If you want to create a Visual Basic project, select Visual Basic, Windows Forms Application and name the project HelloWorld. Click OK.
2. In Solution Explorer, right-click the project HelloWorld and click Add Reference. In the Browse tab, find the folder which you installed the Spire.Presentation in, default is "C:\ProgramFiles\e-iceblue\ Spire.Presentation", double-click the folder Bin. If the target framework of the project HelloWorld
- is .NET 2.0, double-click folder NET2.0
- is .NET 3.5, double-click folder NET3.5
- is .NET 4.0, double-click folder NET4.0
Select assembly Spire.Presentation.dll and click OK to add it to the project.
3. In Solution Explorer, double-click the file Form1.cs/Form1.vb to open the form design view, add a button into the form, and change its name to 'btnRun', change its text to 'Run'.
4. Double-click the button 'Run', you will see the code view and the following method has been added automatically:
private void btnRun_Click(object sender, EventArgs e)
Private Sub btnRun_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRun.Click
5. Add the following codes to the top of the file:
using Spire.Presentation; using Spire.Presentation.Drawing;
Imports Spire.Presentation Imports Spire.Presentation.Drawing
6. Add the following codes to the method btnRun_Click
//create PPT document
Presentation presentation = new Presentation();
//add new shape to PPT document
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle,
new RectangleF(0, 50, 200, 50));
shape.ShapeStyle.LineColor.Color = Color.White;
shape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.None;
//add text to shape
shape.AppendTextFrame("Hello World!");
//set the Font fill style of text
TextRange textRange = shape.TextFrame.TextRange;
textRange.Fill.FillType = Presentation.Drawing.FillFormatType.Solid;
textRange.Fill.SolidColor.Color = Color.Black;
textRange.LatinFont = new TextFont("Arial Black");
//save the document
presentation.SaveToFile("hello.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("hello.pptx");
'create PPT document
Dim presentation As New Presentation()
'add new shape to PPT document
