Animera PowerPoint-diagram i .NET

Introduktion

Aspose.Slides för .NET stöder animering av diagrammets element. Serier, Kategorier, Serieelement, Kategorielelement kan animeras med ISequence.AddEffect metoden och två uppräkningar EffectChartMajorGroupingType och EffectChartMinorGroupingType.

Diagramserieanimation

Om du vill animera en diagramserie, skriv koden enligt stegen nedan:

  1. Läs in en presentation.
  2. Hämta referensen till diagramobjektet.
  3. Animera serien.
  4. Skriv presentationsfilen till disk.

I exemplet nedan animerade vi diagramserier.

 // Instansiera Presentation-klass som representerar en presentationsfil 
using (Presentation presentation = new Presentation("ExistingChart.pptx"))
{
    // Hämta referensen till diagramobjektet
    var slide = presentation.Slides[0] as Slide;
    var shapes = slide.Shapes as ShapeCollection;
    var chart = shapes[0] as IChart;

    // Animera serien
    slide.Timeline.MainSequence.AddEffect(chart, EffectType.Fade, EffectSubtype.None,
    EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
    EffectChartMajorGroupingType.BySeries, 0,
    EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
    EffectChartMajorGroupingType.BySeries, 1,
    EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
    EffectChartMajorGroupingType.BySeries, 2,
    EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
    EffectChartMajorGroupingType.BySeries, 3,
    EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    // Skriv den modifierade presentationen till disk 
    presentation.Save("AnimatingSeries_out.pptx", SaveFormat.Pptx);
}

Diagramkategorianimation

Om du vill animera en diagramkategori, skriv koden enligt stegen nedan:

  1. Läs in en presentation.
  2. Hämta referensen till diagramobjektet.
  3. Animera kategorin.
  4. Skriv presentationsfilen till disk.

I exemplet nedan animerade vi diagramkategorier.

using (Presentation presentation = new Presentation("ExistingChart.pptx"))
{
    // Hämta referensen till diagramobjektet
    var slide = presentation.Slides[0] as Slide;
    var shapes = slide.Shapes as ShapeCollection;
    var chart = shapes[0] as IChart;

    // Animera kategoriernas element
    slide.Timeline.MainSequence.AddEffect(chart, EffectType.Fade, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 0, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 0, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 0, 2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 0, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 1, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 1, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 1, 2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 1, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 2, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 2, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 2, 2, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart, EffectChartMinorGroupingType.ByElementInCategory, 2, 3, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    // Skriv presentationsfilen till disk
    presentation.Save("AnimatingCategoriesElements_out.pptx", SaveFormat.Pptx);
}

FAQ

Stöds olika effektstyper (t.ex. inträde, betoning, utgång) för diagram på samma sätt som för vanliga former?

Ja. Ett diagram behandlas som en form, så det stöder de standardanimatieffekttyperna, inklusive inträde, betoning och utgång, med full kontroll via bildens tidslinje och animationssekvenser.

Kan jag kombinera diagramanimation med bildövergångar?

Ja. Transitions gäller hela bilden, medan animationseffekter gäller objekt på bilden. Du kan använda båda tillsammans i samma presentation och styra dem oberoende.

Behålls diagramanimationer när du sparar till PPTX?

Ja. När du sparar till PPTX bevaras alla animationseffekter och deras ordning eftersom de är en del av presentationens inbyggda animationsmodell.

Kan jag läsa befintliga diagramanimationer från en presentation och ändra dem?

Ja. API ger åtkomst till bildens tidslinje, sekvenser och effekter, så att du kan inspektera befintliga diagramanimationer och justera dem utan att återskapa allt från början.

Kan jag skapa en video som inkluderar diagramanimationer med Aspose.Slides?

Ja. Du kan exportera en presentation till video samtidigt som du bevarar animationerna, konfigurerar tidsinställningar och andra exportalternativ så att den resulterande klippet återger den animerade uppspelningen.
