How to set Smooth Start and End for animated shapes in Presentation
The PowerPoint framework is a feature rich .NET PowerPoint class library that can be used by developers to create, read, edit and convert PowerPoint files to PDFs and images programmatically without Office or interop dependencies.
Steps to set Smooth Start and Smooth End effects for the Shapes in presentation:
- Create a new C# console application project.
- Install the Syncfusion.Presentation.WinForms NuGet package as a reference to your .NET Framework applications from NuGet.org
- Include the following namespace in the Program.cs file.
C#
using Syncfusion.Presentation;
VB
Imports Syncfusion.Presentation
- Use the following code example to set Smooth Start and Smooth End effects for the Shapes in presentation
C#
// Create a new presentation.
IPresentation ppDoc = Presentation.Create();
// Add a slide to the presentation.
ISlide slide = ppDoc.Slides.Add(SlideLayoutType.Blank);
// Add shape on the slide
IShape shape = slide.Shapes.AddShape(AutoShapeType.Diamond, 150, 150, 250, 150);
// Add animation effect on the slide with shape
IEffect effect = ppDoc.Slides[0].Timeline.MainSequence.AddEffect(shape, EffectType.PathSineWave, EffectSubtype.None, EffectTriggerType.OnClick);
// Set smooth start as 2 seconds in Accelerate property
// Note: Set Accelerate and Decelerate property value in 0.5 ratio.
// For example, if you need to set 1 sec means, set value as 0.5f.
effect.Timing.Accelerate = 1f;
// Set smooth end as 0 seconds in Decelerate property
effect.Timing.Decelerate = 0;
// Save the presentation file
ppDoc.Save("Sample.pptx");
// Close the presentation file
ppDoc.Close();
VB
' Create a new presentation.
Dim ppDoc As IPresentation = Presentation.Create()
' Add a slide to the presentation.
Dim slide As ISlide = ppDoc.Slides.Add(SlideLayoutType.Blank)
' Add shape on the slide
Dim shape As IShape = slide.Shapes.AddShape(AutoShapeType.Diamond, 150, 150, 250, 150)
'Add animation effect on the slide with shape
Dim effect As IEffect = ppDoc.Slides(0).Timeline.MainSequence.AddEffect(shape, EffectType.PathSineWave, EffectSubtype.None, EffectTriggerType.OnClick)
' Set smooth start as 2 seconds in Accelerate property
' Note Set Accelerate And Decelerate property value in 0.5 ratio.
' For example, if you need to set 1 sec means, set value as 0.5f.
effect.Timing.Accelerate = 1.0F
' Set smooth end as 0 seconds in Decelerate property
effect.Timing.Decelerate = 0
' Save the presentation file
ppDoc.Save("Sample.pptx")
'Close the presentation file
ppDoc.Close()
