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.

Presentation pres = new Presentation();
try {
    IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.ClusteredColumn, 10, 10, 400, 300);
    String result = chart.getChartData().getRange();
} finally {
    if (pres != null) pres.dispose();
}

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.

or

In Aspose.Slides, to provide the same options for the Sketched Style effect, LineSketchType class and interface ISketchFormat interface have been added. getSketchFormat()  method (of ISketchFormat type) has been added to the ILineFormat interface.

LineSketchType Enum

The LineSketchType determines the preset sketched style.

Below is the definition of the LineSketchType class: 

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

ISketchFormat Interface

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

/**
 * <p>
 * Represents properties for lines sketch format.
 * </p>
 */
public interface ISketchFormat
{
    /**
     * <p>
     * Returns or sets the sketch type.
     * Read/write {@link LineSketchType}.
     * </p>
     */
    public int getSketchType();
    /**
     * <p>
     * Returns or sets the sketch type.
     * Read/write {@link LineSketchType}.
     * </p>
     */
    public void setSketchType(int value);
}

SketchFormat property of ISketchFormat type has been added into ILineFormat:

/**
 * <p>
 * Returns the sketch format of a line.
 * Read-only {@link ISketchFormat}.
 * </p>
 */
public ISketchFormat getSketchFormat();

Example

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

Presentation pres = new Presentation();
try {
    IAutoShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 20, 20, 300, 150);
    shape.getFillFormat().setFillType(FillType.NoFill);

    // Transform shape to sketch of a freehand style
    shape.getLineFormat().getSketchFormat().setSketchType(LineSketchType.Freehand);

    pres.save("sketch.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

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