动画图表

Aspose.Slides for Python via .NET 支持对图表元素进行动画处理。系列、类别、系列元素、类别元素可以通过 ISequence.AddEffect 方法和两个枚举 EffectChartMajorGroupingType 和 EffectChartMinorGroupingType 进行动画处理。

图表系列动画

如果要动画图表系列，请按照以下步骤编写代码：

  1. 加载演示文稿。
  2. 获取图表对象的引用。
  3. 动画系列。
  4. 将演示文稿文件写入磁盘。

在下面的示例中，我们对图表系列进行了动画处理。

import aspose.slides.animation as anim;
import aspose.slides as slides

# 实例化 Presentation 类表示一个演示文稿文件 
with slides.Presentation(path + "ExistingChart.pptx") as presentation:
    # 获取图表对象的引用
    slide = presentation.slides[0]
    shapes = slide.shapes
    chart = shapes[0]

    # 动画系列
    slide.timeline.main_sequence.add_effect(chart, 
        anim.EffectType.FADE, 
        anim.EffectSubtype.NONE, 
        anim.EffectTriggerType.AFTER_PREVIOUS)

    slide.timeline.main_sequence.add_effect(chart, 
        anim.EffectChartMajorGroupingType.BY_SERIES, 0, 
        anim.EffectType.APPEAR, 
        anim.EffectSubtype.NONE, 
        anim.EffectTriggerType.AFTER_PREVIOUS)

    slide.timeline.main_sequence.add_effect(chart,
        anim.EffectChartMajorGroupingType.BY_SERIES, 1,
        anim.EffectType.APPEAR, 
        anim.EffectSubtype.NONE, 
        anim.EffectTriggerType.AFTER_PREVIOUS)

    slide.timeline.main_sequence.add_effect(chart,
        anim.EffectChartMajorGroupingType.BY_SERIES, 2,
        anim.EffectType.APPEAR, 
        anim.EffectSubtype.NONE, 
        anim.EffectTriggerType.AFTER_PREVIOUS)

    slide.timeline.main_sequence.add_effect(chart,
        anim.EffectChartMajorGroupingType.BY_SERIES, 3,
        anim.EffectType.APPEAR, 
        anim.EffectSubtype.NONE, 
        anim.EffectTriggerType.AFTER_PREVIOUS)

    # 将修改后的演示文稿写入磁盘 
    presentation.save("AnimatingSeries_out.pptx", slides.export.SaveFormat.PPTX)

图表类别动画

如果要动画图表类别，请按照以下步骤编写代码：

  1. 加载演示文稿。
  2. 获取图表对象的引用。
  3. 动画类别。
  4. 将演示文稿文件写入磁盘。

在下面的示例中，我们对图表类别进行了动画处理。

import aspose.slides.animation as anim;
import aspose.slides as slides

with slides.Presentation(path + "ExistingChart.pptx") as presentation:
    # 获取图表对象的引用
    slide = presentation.slides[0]
    shapes = slide.shapes
    chart = shapes[0]

    # 动画类别元素
    slide.timeline.main_sequence.add_effect(chart, anim.EffectType.FADE, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 0, 0, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 0, 1, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 0, 2, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 0, 3, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)

    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 1, 0, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 1, 1, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 1, 2, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 1, 3, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)

    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 2, 0, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 2, 1, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 2, 2, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_CATEGORY, 2, 3, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)

    # 将演示文稿文件写入磁盘
    presentation.save("AnimatingCategoriesElements_out.pptx", slides.export.SaveFormat.PPTX)

系列元素中的动画

如果要动画系列元素，请按照以下步骤编写代码：

  1. 加载演示文稿。
  2. 获取图表对象的引用。
  3. 动画系列元素。

    # 动画系列元素
    slide.timeline.main_sequence.add_effect(chart, anim.EffectType.FADE, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)

    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_SERIES, 0, 0, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_SERIES, 0, 1, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
    slide.timeline.main_sequence.add_effect(chart, anim.EffectChartMinorGroupingType.BY_ELEMENT_IN_SERIES, 0, 2, anim.EffectType.APPEAR, anim.EffectSubtype.NONE, anim.EffectTriggerType.AFTER_PREVIOUS)
