Animasi Diagram PowerPoint di Android

Pendahuluan

Aspose.Slides for Android via Java mendukung animasi elemen diagram. Series, Categories, Series Elements, Categories Elements dapat dianimasikan dengan ISequence.addEffect method dan dua enum EffectChartMajorGroupingType dan EffectChartMinorGroupingType.

Animasi Seri Diagram

Jika Anda ingin menganimasi seri diagram, tulis kode sesuai langkah-langkah di bawah ini:

  1. Muat presentasi.
  2. Dapatkan referensi objek diagram.
  3. Animasi seri.
  4. Tuliskan file presentasi ke disk.

Pada contoh di bawah, kami menganimasi seri diagram.

// Instansiasi kelas Presentation yang mewakili file presentasi
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    // Dapatkan referensi objek diagram
    ISlide slide = pres.getSlides().get_Item(0);
    IShapeCollection shapes = slide.getShapes();
    IChart chart = (IChart) shapes.get_Item(0);

    // Animasi seri
    slide.getTimeline().getMainSequence().addEffect(chart, EffectType.Fade, EffectSubtype.None,
            EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.BySeries, 0,
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.BySeries, 1,
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.BySeries, 2,
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.BySeries, 3,
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    // Tuliskan presentasi yang dimodifikasi ke disk
    pres.save("AnimatingSeries_out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Animasi Kategori Diagram

Jika Anda ingin menganimasi kategori diagram, tulis kode sesuai langkah-langkah di bawah ini:

  1. Muat presentasi.
  2. Dapatkan referensi objek diagram.
  3. Animasi Kategori.
  4. Tuliskan file presentasi ke disk.

Pada contoh di bawah, kami menganimasi kategori diagram.

// Instansiasi kelas Presentation yang mewakili file presentasi
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    ISlide slide = pres.getSlides().get_Item(0);
    IShapeCollection shapes = slide.getShapes();
    IChart chart = (IChart) shapes.get_Item(0);

    slide.getTimeline().getMainSequence().addEffect(chart, EffectType.Fade, EffectSubtype.None,
            EffectTriggerType.AfterPrevious);

    ((Sequence) slide.getTimeline().getMainSequence()).addEffect(chart,
            EffectChartMajorGroupingType.ByCategory, 0, 
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    
    ((Sequence) slide.getTimeline().getMainSequence()).addEffect(chart, 
            EffectChartMajorGroupingType.ByCategory, 1, 
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    
    ((Sequence) slide.getTimeline().getMainSequence()).addEffect(chart, 
            EffectChartMajorGroupingType.ByCategory, 2, 
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    
    ((Sequence) slide.getTimeline().getMainSequence()).addEffect(chart, 
            EffectChartMajorGroupingType.ByCategory, 3, 
            EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    pres.save("Sample_Animation_C.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Animasi pada Elemen Seri

Jika Anda ingin menganimasi elemen seri, tulis kode sesuai langkah-langkah di bawah ini:

  1. Muat presentasi.
  2. Dapatkan referensi objek diagram.
  3. Animasi elemen seri.
  4. Tuliskan file presentasi ke disk.

Pada contoh di bawah, kami telah menganimasi elemen seri.

// Instansiasi kelas Presentation yang mewakili file presentasi
Presentation pres = new Presentation("ExistingChart.pptx");
try {
    // Dapatkan referensi objek diagram
    ISlide slide = pres.getSlides().get_Item(0);
    IShapeCollection shapes = slide.getShapes();
    IChart chart = (IChart) shapes.get_Item(0);

    // Animasi elemen seri
    slide.getTimeline().getMainSequence().addEffect(chart, EffectType.Fade, EffectSubtype.None, EffectTriggerType.AfterPrevious);

    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            0, 0, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.getTimeline().getMainSequence()).addEffect(chart, EffectChartMinorGroupingType.ByElementInSeries, 
            0, 1, EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);

Jika Anda ingin menganimasi elemen kategori, tulis kode sesuai langkah-langkah di bawah ini:

  1. Muat presentasi.
  2. Dapatkan referensi objek diagram.
  3. Animasi elemen kategori.
  4. Tuliskan file presentasi ke disk.

FAQ

Apakah tipe efek yang berbeda (mis., entrance, emphasis, exit) didukung untuk diagram seperti pada bentuk biasa?

Ya. Diagram diperlakukan sebagai bentuk, sehingga mendukung tipe efek animasi standar, termasuk entrance, emphasis, dan exit, dengan kontrol penuh melalui timeline slide dan urutan animasi.

Apakah saya dapat menggabungkan animasi diagram dengan transisi slide?

Ya. Transitions diterapkan pada slide, sementara efek animasi diterapkan pada objek di slide. Anda dapat menggunakan keduanya bersama dalam presentasi yang sama dan mengontrolnya secara independen.

Apakah animasi diagram dipertahankan saat menyimpan ke PPTX?

Ya. Ketika Anda save to PPTX, semua efek animasi dan urutannya dipertahankan karena merupakan bagian dari model animasi asli presentasi.

Apakah saya dapat membaca animasi diagram yang ada dari presentasi dan memodifikasinya?

Ya. API memberikan akses ke timeline slide, urutan, dan efek, memungkinkan Anda memeriksa animasi diagram yang ada dan menyesuaikannya tanpa harus membuat semuanya dari awal.

Apakah saya dapat menghasilkan video yang menyertakan animasi diagram menggunakan Aspose.Slides?

Ya. Anda dapat export a presentation to video sambil mempertahankan animasi, mengonfigurasi waktu dan pengaturan ekspor lainnya sehingga klip yang dihasilkan mencerminkan pemutaran animasi.
