C# Set animation effect for the animate text on the presentation slides
We have already demonstrated how to set the animations on shapes in PowerPoint. Now Spire.Presentation starts to support set the Animation Effect for the type and time of the animate text. This article will show you how to use IterateType property and IterateTimeValue property for animation Effect to set the type and time of animate text in C#.
Firstly, view the original sample document with animate text effect with "All at once".
Step 1: Create a presentation instance and load the sample document from file.
Presentation ppt = new Presentation();
ppt.LoadFromFile("Sample.pptx",FileFormat.Pptx2010);
Step 2: Set the AnimateType as Letter.
ppt.Slides[0].Timeline.MainSequence[0].IterateType = Spire.Presentation.Drawing.TimeLine.AnimateType.Letter;
Step 3: Set the IterateTimeValue for the animate text.
ppt.Slides[0].Timeline.MainSequence[0].IterateTimeValue = 10;
Step 4: Save the document to file.
ppt.SaveToFile("Result.pptx", FileFormat.Pptx2010);

Reset the size and position for the shape on presentation slides in C#
Every time when we change the slide's size, we need to reset the size and position for the shape to ensure the shape on the slide shows orderly. This tutorial will focus on demonstrating how to reset the size and position for the shape in C#.
Firstly, please view the original shape:
Code snippet of how to set the size and position of the shape:
Step 1: Create a new presentation document and load the document from file.
Presentation presentation = new Presentation();
presentation.LoadFromFile("Sample.pptx");
Step 2: Define the original slide size.
float currentHeight = presentation.SlideSize.Size.Height; float currentWidth = presentation.SlideSize.Size.Width;
Step 3: Change the slide size as A3.
presentation.SlideSize.Type = SlideSizeType.A3;
Step 4: Define the new slide size.
float newHeight = presentation.SlideSize.Size.Height; float newWidth = presentation.SlideSize.Size.Width;
Step 5: Define the ratio from the old and new slide size.
float ratioHeight = newHeight / currentHeight; float ratioWidth = newWidth / currentWidth;
Step 6: Reset the size and position of the shape on the slide.
foreach (ISlide slide in presentation.Slides)
{
foreach (IShape shape in slide.Shapes)
{
//Reset the shape size
shape.Height = shape.Height * ratioHeight;
shape.Width = shape.Width * ratioWidth;
//Reset the shape position
shape.Left = shape.Left * ratioHeight;
shape.Top = shape.Top * ratioWidth;
}
Step 7: Save the document to file.
presentation.SaveToFile("resize.pptx", FileFormat.Pptx2010);

How to Add an Image to Slide Master in C#, VB.NET
A slide master is the top slide that stores the information about the theme and slide layouts, which will be inherited by other slides in the presentation. In other words, when you modify the style of slide master, every slide in the presentation will be changed accordingly, including the ones added later.
This quality makes it possible that when you want to insert an image or watermark to every slide, you only need to insert the image in slide master. In this article, you'll learn how to add an image to slide master using Spire.Presenation in C#, VB.NET.
Screenshot of original file:
Detailed Steps:
Step 1: Initialize a new Presentation and load the sample file
Presentation presentation = new Presentation(); presentation.LoadFromFile(@"sample.pptx");
Step 2: Get the master collection.
IMasterSlide master = presentation.Masters[0];
Step 3: Insert an image to slide master.
String image = @"logo.png"; RectangleF rff = new RectangleF(40, 40, 100, 80); IEmbedImage pic=master.Shapes.AppendEmbedImage(ShapeType.Rectangle, image, rff); pic.Line.FillFormat.FillType = FillFormatType.None;
Step 4: Add a new blank slide to the presentation.

How to set 3-D format for shapes in slides
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;

How to prevent or allow changes to shapes
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;
