Aspose.Slides for .NET是一個(gè)獨(dú)特的演示處理API，它允許應(yīng)用程序讀取、寫入、修改和轉(zhuǎn)換PowerPoint演示文稿。作為一個(gè)獨(dú)立的API，它提供了管理PowerPoint關(guān)鍵功能的功能，如管理文本、形狀、表格和動(dòng)畫、向幻燈片添加音頻和視頻、預(yù)覽幻燈片等，而不需要Microsoft PowerPoint。

Aspose.Slides for .NET迎來(lái)2020年8月更新v20.8，支持Aspsoe中的Redact文本，支持圖表數(shù)據(jù)的GetRange（）方法，支持SketchStyle屬性，并有1個(gè)功能正在研究中。（點(diǎn)擊下方按鈕即可下載）

公共API更改

添加IChartData.GetRange方法

已添加新方法 IChartData.GetRange。該方法返回圖表使用的工作簿數(shù)據(jù)范圍。IChartData.GetRange方法返回字符串值。

返回的值看起來(lái)像“ Sheet1！$ A $ 1：$ D $ 5”，其中“ Sheet1”是源工作表，$ A $ 1：$ D $ 5是一個(gè)單元格區(qū)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“形狀草圖樣式”效果

草繪樣式效果功能有助于更改幻燈片中的形狀外觀，從而迫使形狀看起來(lái)像草圖。它將手繪（或“草圖”）樣式應(yīng)用于形狀。

下圖演示了PowerPoint UI元素將此效果應(yīng)用于形狀。

在Aspose.Slides中，為了為“草繪樣式”效果提供相同的選項(xiàng)，已添加了枚舉LineSketchType和接口ISketchFormat。SketchFormat屬性（int SketchFormat類型）已添加到ILineFormat接口。

添加LineSketchType枚舉

所述LineSketchType確定預(yù)設(shè)繪制風(fēng)格。以下是LineSketchType枚舉的定義：

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

已添加帶有SketchFormat實(shí)現(xiàn)類的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財(cái)產(chǎn)ISketchFormat類型已添加到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為形狀設(shè)置草圖類型：

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);
}

通過(guò)上面的代碼片段生成的形狀邊界線樣式具有以下外觀：
