Public API Changes

IChartData.GetRange method has been added

IChartData.GetRange method has been added. The method returns the workbook data range that is used by the chart. IChartData.GetRange method returns a string value.

The returned value looks like “Sheet1!$A$1:$D$5” where “Sheet1” is a source worksheet and $A$1:$D$5 is a cell range.

Using IChartData.GetRange() method example.

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

Shape Sketched Style effect has been added

Sketched Style effect feature helps to change the appearance of shapes in a slide forcing shapes to look like a sketch. It applies a hand-drawn (or “sketched”) styling to shapes.

The picture below demonstrates PowerPoint UI elements to apply this effect to a shape.

todo:image_alt_text or todo:image_alt_text

In Aspose.Slides, to provide the same options for the Sketched Style effect, enum LineSketchType and interface ISketchFormat have been added. SketchFormat property (int SketchFormat type) has been added to the ILineFormat interface.

LineSketchType Enum

The LineSketchType determines the preset sketched style.

Below is the definition of the LineSketchType enum:

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

ISketchFormat Interface

The ISketchFormat interface with the SketchFormat implementation class has been added:

/// <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 property of ISketchFormat type has been added into ILineFormat:

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


The example below demonstrates how to set sketchy type for a shape:

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);

The shape border line style generated via the code snippet above has the following appearance:
