公共 API 更改

添加的接口、方法和属性

新增 Aspose.Slides.Charts.IErrorBarsFormat 接口

此接口表示图表系列的误差条。

在自定义值类型的情况下，要指定一个值，请使用系列的 DataPoints 集合中特定数据点的 ErrorBarCustomValues 属性。

 using (Presentation pres = new Presentation())

{

    IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.Bubble, 50, 50, 400, 300, true);

    IErrorBarsFormat errBarX = chart.ChartData.Series[0].ErrorBarsXFormat;

    IErrorBarsFormat errBarY = chart.ChartData.Series[0].ErrorBarsYFormat;

    errBarX.IsVisible = true;

    errBarY.IsVisible = true;

    errBarX.ValueType = ErrorBarValueType.Fixed;

    errBarX.Value = 0.1f;

    errBarY.ValueType = ErrorBarValueType.Percentage;

    errBarY.Value = 5;

    errBarX.Type = ErrorBarType.Plus;

    errBarY.Format.Line.Width = 2;

    errBarX.HasEndCap = true;

    pres.Save("ErrorBars.pptx", SaveFormat.Pptx);

}

新增 Aspose.Slides.Charts.IErrorBarsCustomValues 接口

当 IErrorBarsFormat.ValueType 属性等于 Custom 时，要指定一个值，请使用 DataPoints 集合中特定数据点的 ErrorBarCustomValues 属性。

 using (Presentation pres = new Presentation())

{

    IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.Bubble, 50, 50, 400, 300, true);

    IChartSeries series = chart.ChartData.Series[0];

    IErrorBarsFormat errBarX = series.ErrorBarsXFormat;

    IErrorBarsFormat errBarY = series.ErrorBarsYFormat;

    errBarX.IsVisible = true;

    errBarY.IsVisible = true;

    errBarX.ValueType = ErrorBarValueType.Custom;

    errBarY.ValueType = ErrorBarValueType.Custom;

    IChartDataPointCollection points = series.DataPoints;

    points.DataSourceTypeForErrorBarsCustomValues.DataSourceTypeForXPlusValues = DataSourceType.DoubleLiterals;

    points.DataSourceTypeForErrorBarsCustomValues.DataSourceTypeForXMinusValues = DataSourceType.DoubleLiterals;

    points.DataSourceTypeForErrorBarsCustomValues.DataSourceTypeForYPlusValues = DataSourceType.DoubleLiterals;

    points.DataSourceTypeForErrorBarsCustomValues.DataSourceTypeForYMinusValues = DataSourceType.DoubleLiterals;

    for (int i = 0; i < points.Count; i++)

    {

        points[i].ErrorBarsCustomValues.XMinus.AsLiteralDouble = i + 1;

        points[i].ErrorBarsCustomValues.XPlus.AsLiteralDouble = i + 1;

        points[i].ErrorBarsCustomValues.YMinus.AsLiteralDouble = i + 1;

        points[i].ErrorBarsCustomValues.YPlus.AsLiteralDouble = i + 1;

    }

    pres.Save("ErrorBarsCustomValues", SaveFormat.Pptx);

}

新增 Aspose.Slides.Charts.IDataSourceTypeForErrorBarsCustomValues 接口

指定 ChartDataPoint.ErrorBarsCustomValues 属性列表中值的类型。

 using (Presentation pres = new Presentation())

{

    IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.Bubble, 50, 50, 400, 300, true);

    IChartSeries series = chart.ChartData.Series[0];

    IErrorBarsFormat errBarX = series.ErrorBarsXFormat;

    IErrorBarsFormat errBarY = series.ErrorBarsYFormat;

    errBarX.IsVisible = true;

    errBarY.IsVisible = true;

    errBarX.ValueType = ErrorBarValueType.Custom;

    errBarY.ValueType = ErrorBarValueType.Custom;

    IChartDataPointCollection points = series.DataPoints;

    points.DataSourceTypeForErrorBarsCustomValues.DataSourceTypeForXPlusValues = DataSourceType.DoubleLiterals;

    points.DataSourceTypeForErrorBarsCustomValues.DataSourceTypeForXMinusValues = DataSourceType.DoubleLiterals;

    points.DataSourceTypeForErrorBarsCustomValues.DataSourceTypeForYPlusValues = DataSourceType.DoubleLiterals;

    points.DataSourceTypeForErrorBarsCustomValues.DataSourceTypeForYMinusValues = DataSourceType.DoubleLiterals;

    for (int i = 0; i < points.Count; i++)

    {

        points[i].ErrorBarsCustomValues.XMinus.AsLiteralDouble = i + 1;

        points[i].ErrorBarsCustomValues.XPlus.AsLiteralDouble = i + 1;

        points[i].ErrorBarsCustomValues.YMinus.AsLiteralDouble = i + 1;

        points[i].ErrorBarsCustomValues.YPlus.AsLiteralDouble = i + 1;

    }

    pres.Save("ErrorBarsCustomValues", SaveFormat.Pptx);

}

新增 Aspose.Slides.IShapeCollection.AddClone(…)、.InsertClone(…) 方法

以下方法将指定形状的副本添加/插入到集合中。

• Aspose.Slides.IShapeCollection.AddClone(IShape sourceShape)
• Aspose.Slides.IShapeCollection.AddClone(IShape sourceShape, float x, float y)
• Aspose.Slides.IShapeCollection.AddClone(IShape sourceShape, float x, float y, float width, float height)
• Aspose.Slides.IShapeCollection.InsertClone(int index, IShape sourceShape)
• Aspose.Slides.IShapeCollection.InsertClone(int index, IShape sourceShape, float x, float y)
• Aspose.Slides.IShapeCollection.InsertClone(int index, IShape sourceShape, float x, float y, float width, float height)

 using (Presentation srcPres = new Presentation(dataPath_ShapeCloning + "Source Frame.pptx"))

{

    IShapeCollection sourceShapes = srcPres.Slides[0].Shapes;

    ILayoutSlide blankLayout = srcPres.Masters[0].LayoutSlides.GetByType(SlideLayoutType.Blank);

    ISlide destSlide = srcPres.Slides.AddEmptySlide(blankLayout);

    IShapeCollection destShapes = destSlide.Shapes;

    destShapes.AddClone(sourceShapes[1], 50, 150 + sourceShapes[0].Height);

    destShapes.AddClone(sourceShapes[2]);

    destShapes.AddClone(sourceShapes[3], 50, 200, 50, 50);

    destShapes.AddClone(sourceShapes[4]);

    destShapes.AddClone(sourceShapes[5], 300, 300, 50, 200);

    destShapes.InsertClone(0, sourceShapes[0], 50, 150);

}

新增 ViewType 枚举、IViewProperties 接口、ViewProperties 类和 IPresentation.ViewProperties 属性

IPresentation.ViewProperty 允许开发者在 PowerPoint 中打开演示文稿时更改演示文稿视图类型和备注的可见性。

 using(Presentation p = new Presentation())

{

    p.ViewProperties.LastView = ViewType.SlideMasterView;

}
