Editor to share with you how to add, modify and delete animation in C# PowerPoint, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

In order to make the PowerPoint document more beautiful, we usually add animation to the elements in the PowerPoint document, such as shapes, pictures, tables, etc. This article shows you how to use the .NET PowerPoint components Spire.Presentation and C # to programmatically animate shapes in PowerPoint and modify and delete existing animations.

Before we begin, we can take a look at the animation in PowerPoint. In PowerPoint, animation can be roughly divided into the following four categories:

1. Enter

two。 Emphasize

3. Quit

4. Action path

Among them, there are many different preset animation effects under the entry, emphasis and exit types, and some animation effects can also be added, such as the Random Line animation effects under the entry category. You can set horizontal or vertical direction sub-effects (the default is horizontal). The following figure shows how to add animation to PowerPoint:

How to add Animation in Spire.Presentation

Spire.Presentation supports about 151animation effects (which can be seen in the AnimationEffectType enumeration). See the table at the end of the article for these animation effects and their categories and sub-effects.

Before using the following code, you need to download the Spire.Presentation installation and reference Spire.Presentation.dll from the installation path to the project (or you can search for Spire.Presentation from NuGet and install it).

Add Animation

/ / load the document Presentation ppt = new Presentation (); ppt.LoadFromFile ("Input.pptx"); / / get the first slide ISlide slide = ppt.Slides [0]; RectangleF rect = new RectangleF (50,200,200,200); / / add shapes to the slide IShape cubeShape = slide.Shapes.AppendShape (ShapeType.Cube, rect); / / add animation to shapes AnimationEffectCollection sequence = slide.Timeline.MainSequence;AnimationEffect effect = sequence.AddEffect (cubeShape, AnimationEffectType.Bounce) / / Save document ppt.SaveToFile ("Output.pptx", FileFormat.Pptx2013)

Usually the animation effect we add is the "enter" effect by default. The following code describes how to add the "exit" animation effect:

/ / load the document Presentation ppt = new Presentation (); ppt.LoadFromFile ("Input.pptx"); / / get the first slide ISlide slide = ppt.Slides [0]; RectangleF rect = new RectangleF (50,200,200,200); / / add shapes to the slide IShape cubeShape = slide.Shapes.AppendShape (ShapeType.Cube, rect); / / add animation to shapes AnimationEffectCollection sequence = slide.Timeline.MainSequence;AnimationEffect effect = sequence.AddEffect (cubeShape, AnimationEffectType.RandomBars) / / change the animation effect from the default "enter" effect to "exit" effect effect.PresetClassType = TimeNodePresetClassType.Exit;// add sub-effects to the animation effect.Subtype = AnimationEffectSubtype.Vertical; / / Save the document ppt.SaveToFile ("ExitAnimationEffect.pptx", FileFormat.Pptx2013)

Modify animation

We can modify the existing animation in the document. The following code describes how to modify the type and duration of an existing animation.

Modify animation typ

/ / load the document Presentation ppt = new Presentation (); ppt.LoadFromFile ("Output.pptx"); / / get the first slide ISlide slide = ppt.Slides [0]; / / modify the type of the first animation AnimationEffectCollection sequence = slide.Timeline.MainSequence;sequence [0] .AnimationEffectType = AnimationEffectType.GrowAndTurn; / / Save text ppt.SaveToFile ("EditAnimationType.pptx", FileFormat.Pptx2013)

Modification duration

/ / load the document Presentation ppt = new Presentation (); ppt.LoadFromFile ("Output.pptx"); / / get the first slide ISlide slide = ppt.Slides [0]; / / modify the duration of the first animation AnimationEffectCollection sequence = slide.Timeline.MainSequence;sequence [0] .Timing.Duration = 5; / / Save the document ppt.SaveToFile ("EditAnimationTime.pptx", FileFormat.Pptx2013)

Delete animation

/ / load the document Presentation ppt = new Presentation (); ppt.LoadFromFile ("Output.pptx"); / / get the first slide ISlide slide = ppt.Slides [0]; / / delete the first animation AnimationEffectCollection sequence = slide.Timeline.MainSequence;sequence.RemoveAt (0); / / Save the document ppt.SaveToFile ("RemoveAnimation.pptx", FileFormat.Pptx2013)
