Public API and Backwards Incompatible Changes in Aspose.Slides for .NET 15.10.0

Public API Changes

A new VideoPlayerHtmlController added to support export od media files to HTML

The new public class VideoPlayerHtmlController has been added to Aspose.Slides.Export namespace. Using the instance of this class user can export video and audio files into HTML. VideoPlayerHtmlController contructors accepts the following parameters:

path: The path where video and audio files will be generated fileName: The name of the HTML file

baseUri: The base URI which will be used to generate links Usage example:


 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);

}

Chart series animation API has been added

The new 2 methods have been added to Aspose.Slides.Animation.ISequence interface.


 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);

These methods are intended to support the chart’s elements animations: by series by categories by series elements by categories elements

The two new enums EffectChartMajorGroupingType and EffectChartMinorGroupingType related to the chart’s elements animation were introduced.

To add a series animation to the chart the following code may be used:


 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);

}

Categories animation:


 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);

}

    var chart = shapes[0] as IChart;
