添加IChartData.GetRange方法

已添加新方法 IChartData.GetRange。该方法返回图表使用的工作簿数据范围。IChartData.GetRange方法返回字符串值。

返回的值看起来像“ Sheet1！$ A $ 1：$ D $ 5”，其中“ Sheet1”是源工作表，$ A $ 1：$ D $ 5是一个单元格区域。

using (Presentation pres = new Presentation()){    IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn, 10, 10, 400, 300);    string result = chart.ChartData.GetRange();}

添加了“形状草图样式”效果

草绘样式效果功能有助于更改幻灯片中的形状外观，从而迫使形状看起来像草图。它将手绘（或“草图”）样式应用于形状。

下图演示了PowerPoint UI元素将此效果应用于形状。

在Aspose.Slides中，为了为“草绘样式”效果提供相同的选项，已添加了枚举LineSketchType和接口ISketchFormat。SketchFormat属性（int SketchFormat类型）已添加到ILineFormat接口。

添加LineSketchType枚举

所述LineSketchType确定预设绘制风格。以下是LineSketchType枚举的定义：

public enum LineSketchType { /// <summary>  /// Specifies that a shape Sketch effect is undefined.  /// </summary>  NotDefined = -1, /// <summary>  /// Specifies that a shape has no Sketch effect. This is equivalent to this property being empty.  /// </summary>  None = 0, /// <summary>  /// Specifies that a shape has the Curved effect, which turns each edge of the shape into one big gentle curve.  /// </summary>  Curved = 1, /// <summary>  /// Specifies that a shape has the Freehand effect, which most closely resembles an imperfectly drawn line.  /// </summary>  Freehand = 2, /// <summary>  /// Specifies that a shape has the Scribble effect, which has exaggerated oscillation as if drawn purposely messy.  /// </summary>  Scribble = 3 }

添加ISketchFormat接口

已添加带有SketchFormat实现类的ISketchFormat接口：

/// <summary> /// Represents properties for lines sketch format. /// </summary> public interface ISketchFormat { /// <summary>  /// Returns or sets the sketch type.  /// Read/write <see cref="Slides.LineSketchType"/>.  /// </summary>  LineSketchType SketchType { get; set; } }

SketchFormat财产ISketchFormat类型已添加到ILineFormat：

/// <summary> /// Returns the sketch format of a line. /// Read-only <see cref="ISketchFormat"/>. /// </summary> ISketchFormat SketchFormat { get; }

下面的示例演示如何为形状设置草图类型：

using (Presentation pres = new Presentation()){    IAutoShape shape = pres.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 20, 20, 300, 150);    shape.FillFormat.FillType = FillType.NoFill;    // Transform shape to sketch of a freehand style    shape.LineFormat.SketchFormat.SketchType = LineSketchType.Freehand;     pres.Save("sketch.pptx", SaveFormat.Pptx);}

通过上面的代码片段生成的形状边界线样式具有以下外观：
