Aspose.Slides for .NET 15.10.0 中的公共 API 和向后不兼容的更改

此页面列出了所有在 Aspose.Slides for .NET 15.10.0 API 中添加或删除的类、方法、属性等，以及其他更改。

公共 API 更改

新增 VideoPlayerHtmlController 以支持将媒体文件导出为 HTML

已在 Aspose.Slides.Export 命名空间中添加了公共类 VideoPlayerHtmlController。使用该类的实例，用户可以将视频和音频文件导出为 HTML。
VideoPlayerHtmlController 构造函数接受以下参数：

path: 将生成视频和音频文件的路径
fileName: HTML 文件的名称
baseUri: 用于生成链接的基准 URI

使用示例：

 using (Presentation pres = new Presentation("example.pptx"))
{
    const string path = "path";
    const string fileName = "video.html";
    const string baseUri = "http://www.example.com/";
    VideoPlayerHtmlController controller = new VideoPlayerHtmlController(path: path, fileName: fileName, baseUri: baseUri);
    HtmlOptions htmlOptions = new HtmlOptions(controller);
    SVGOptions svgOptions = new SVGOptions(controller);
    htmlOptions.HtmlFormatter = HtmlFormatter.CreateCustomFormatter(controller);
    htmlOptions.SlideImageFormat = SlideImageFormat.Svg(svgOptions);
    pres.Save(Path.Combine(path, fileName), SaveFormat.Html, htmlOptions);
}

已添加 Chart Series Animation API

在 Aspose.Slides.Animation.ISequence 接口中添加了两个新方法。

 IEffect AddEffect(IChart chart, EffectChartMajorGroupingType type, int index, EffectType effectType, EffectSubtype subtype, EffectTriggerType triggerType);
IEffect AddEffect(IChart chart, EffectChartMinorGroupingType type, int seriesIndex, int categoriesIndex, EffectType effectType, EffectSubtype subtype, EffectTriggerType triggerType);

这些方法用于支持图表元素的动画：

按系列
按类别
按系列元素
按类别元素

此外，新增了两个枚举 EffectChartMajorGroupingType 和 EffectChartMinorGroupingType，用于图表元素动画。

为图表添加系列动画的示例代码：

 using (Presentation pres = new Presentation(inFileName))
{
    var slide = pres.Slides[0] as Slide;
    var shapes = slide.Shapes as ShapeCollection;
    var chart = shapes[0] as IChart;
    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);
    pres.Save(outFileName, SaveFormat.Pptx);
}

类别动画示例：

 using (Presentation pres = new Presentation(inFileName))
{
    var slide = pres.Slides[0] as Slide;
    var shapes = slide.Shapes as ShapeCollection;
    var chart = shapes[0] as IChart;
    slide.Timeline.MainSequence.AddEffect(chart, EffectType.Fade, EffectSubtype.None,
        EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
        EffectChartMajorGroupingType.ByCategory, 0,
        EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
        EffectChartMajorGroupingType.ByCategory, 1,
        EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
        EffectChartMajorGroupingType.ByCategory, 2,
        EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
        EffectChartMajorGroupingType.ByCategory, 3,
        EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    pres.Save(outFileName, SaveFormat.Pptx);
}

系列元素动画示例：

 using (Presentation pres = new Presentation(inFileName))
{
    var slide = pres.Slides[0] as Slide;
    var shapes = slide.Shapes as ShapeCollection;
    var chart = shapes[0] as IChart;
    slide.Timeline.MainSequence.AddEffect(chart, EffectType.Fade, EffectSubtype.None,
        EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
        EffectChartMinorGroupingType.ByElementInSeries, 0, 0,
        EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
        EffectChartMinorGroupingType.ByElementInSeries, 0, 1,
        EffectType.Appear, EffectSubtype.None, EffectTriggerType.AfterPrevious);
    ((Sequence)slide.Timeline.MainSequence).AddEffect(chart,
