Animera PowerPoint-diagram i JavaScript

Introduktion

Aspose.Slides för Node.js via Java stöder animering av diagrammets element. Series, Categories, Series Elements, Categories Elements kan animeras med Sequence.addEffect metoden och två uppräkningar EffectChartMajorGroupingType och EffectChartMinorGroupingType.

Animering av diagramserie

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 har vi animerat diagramserien.

// Skapa en Presentation-klass som representerar en presentationsfil
var pres = new aspose.slides.Presentation("ExistingChart.pptx");
try {
    // Hämta referensen till diagramobjektet
    var slide = pres.getSlides().get_Item(0);
    var shapes = slide.getShapes();
    var chart = shapes.get_Item(0);
    // Animera serien
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectType.Fade, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectChartMajorGroupingType.BySeries, 0, aspose.slides.EffectType.Appear, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectChartMajorGroupingType.BySeries, 1, aspose.slides.EffectType.Appear, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectChartMajorGroupingType.BySeries, 2, aspose.slides.EffectType.Appear, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectChartMajorGroupingType.BySeries, 3, aspose.slides.EffectType.Appear, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    // Skriv den ändrade presentationen till disk
    pres.save("AnimatingSeries_out.pptx", aspose.slides.SaveFormat.Pptx);
} finally {
    if (pres != null) {
        pres.dispose();
    }
}

Animering av diagramkategori

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 har vi animerat diagramkategorin.

// Skapa Presentation-klass som representerar en presentationsfil
var pres = new aspose.slides.Presentation("ExistingChart.pptx");
try {
    var slide = pres.getSlides().get_Item(0);
    var shapes = slide.getShapes();
    var chart = shapes.get_Item(0);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectType.Fade, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectChartMajorGroupingType.ByCategory, 0, aspose.slides.EffectType.Appear, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectChartMajorGroupingType.ByCategory, 1, aspose.slides.EffectType.Appear, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectChartMajorGroupingType.ByCategory, 2, aspose.slides.EffectType.Appear, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    slide.getTimeline().getMainSequence().addEffect(chart, aspose.slides.EffectChartMajorGroupingType.ByCategory, 3, aspose.slides.EffectType.Appear, aspose.slides.EffectSubtype.None, aspose.slides.EffectTriggerType.AfterPrevious);
    pres.save("Sample_Animation_C.pptx", aspose.slides.SaveFormat.Pptx);
} finally {
    if (pres != null) {
        pres.dispose();
    }
}

  3. Animera serieelement.
  4. Skriv presentationsfilen till disk.

Vanliga frågor

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

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

Kan jag kombinera diagramanimation med bildövergångar?

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

Behålls diagramanimationer när man sparar till PPTX?

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

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

Ja. API:et ger åtkomst till bildens tidslinje, sekvenser och effekter, vilket låter dig inspektera befintliga diagramanimationer och justera dem utan att återskapa allt från början.

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

Ja. Du kan exportera en presentation till video medan du bevarar animationerna, konfigurerar tidsinställningar och andra exportinställningar så att den resulterande videon återspeglar den animerade uppspelningen.
