Shape Effective Properties

In this topic, we will discuss effective and local properties. When we set values directly at these levels

  1. In portion properties on the portion’s slide;
  2. In prototype shape text style on layout or master slide (if portion’s text frame shape has one);
  3. In presentation global text settings;

those values are called local values. At any level, local values could be defined or omitted. But when an application needs to know what the portion should look like, it uses effective values. You can get effective values by using the getEffective() method from the local format.

This sample code shows you how to get effective values:

Presentation pres = new Presentation("Presentation1.pptx");
try {
    IAutoShape shape = (IAutoShape)pres.getSlides().get_Item(0).getShapes().get_Item(0);

    ITextFrameFormat localTextFrameFormat = shape.getTextFrame().getTextFrameFormat();
    ITextFrameFormatEffectiveData effectiveTextFrameFormat = localTextFrameFormat.getEffective();

    IPortionFormat localPortionFormat = shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat();
    IPortionFormatEffectiveData effectivePortionFormat = localPortionFormat.getEffective();
} finally {
    if (pres != null) pres.dispose();
}

Getting Effective Properties of the Camera

Aspose.Slides for Java allows developers to get effective properties of the camera. For this purpose, the ICameraEffectiveData interface was added to Aspose.Slides. The ICameraEffectiveData interface represents an immutable object that contains effective camera properties. An instance of ICameraEffectiveData interface is used as part of the IThreeDFormatEffectiveData interface, which is an effective values pair for the ThreeDFormat class.

This sample code sample shows you how to get effective properties for the camera:

Presentation pres = new Presentation("Presentation1.pptx");
try {
    IThreeDFormatEffectiveData threeDEffectiveData = pres.getSlides().get_Item(0).getShapes().get_Item(0).getThreeDFormat().getEffective();

    System.out.println("= Effective camera properties =");
    System.out.println("Type: " + threeDEffectiveData.getCamera().getCameraType());
    System.out.println("Field of view: " + threeDEffectiveData.getCamera().getFieldOfViewAngle());
    System.out.println("Zoom: " + threeDEffectiveData.getCamera().getZoom());
} finally {
    if (pres != null) pres.dispose();
}

Getting Effective Properties of Light Rig

Aspose.Slides for Java allows developers to get effective properties of Light Rig. For this purpose, the ILightRigEffectiveData interface was added to Aspose.Slides. The ILightRigEffectiveData interface represents an immutable object that contains effective light rig properties. An instance of the ILightRigEffectiveData interface is used as part of IThreeDFormatEffectiveData interface, which is an effective values pair for the ThreeDFormat class.

This sample code sample shows you how to get effective properties of Light Rig:

Presentation pres = new Presentation("Presentation1.pptx");
try {
    IThreeDFormatEffectiveData threeDEffectiveData = pres.getSlides().get_Item(0).getShapes().get_Item(0).getThreeDFormat().getEffective();

    System.out.println("= Effective light rig properties =");
    System.out.println("Type: " + threeDEffectiveData.getLightRig().getLightType());
    System.out.println("Direction: " + threeDEffectiveData.getLightRig().getDirection());
} finally {
    if (pres != null) pres.dispose();
}

Getting Effective Properties of Bevel Shape

Aspose.Slides for Java allows developers to get effective properties of Bevel Shape. For this purpose, the IShapeBevelEffectiveData interface was added to Aspose.Slides. The IShapeBevelEffectiveData interface represents an immutable object that contains effective shape’s face relief properties. An instance of the IShapeBevelEffectiveData interface is used as part of IThreeDFormatEffectiveData interface, which is an effective values pair for ThreeDFormat class.

This sample code sample shows you how to get effective properties for the Bevel Shape:

Presentation pres = new Presentation("Presentation1.pptx");
try {
    IThreeDFormatEffectiveData threeDEffectiveData = pres.getSlides().get_Item(0).getShapes().get_Item(0).getThreeDFormat().getEffective();

    System.out.println("= Effective shape's top face relief properties =");
    System.out.println("Type: " + threeDEffectiveData.getBevelTop().getBevelType());
    System.out.println("Width: " + threeDEffectiveData.getBevelTop().getWidth());
    System.out.println("Height: " + threeDEffectiveData.getBevelTop().getHeight());
} finally {
    if (pres != null) pres.dispose();
}

Getting Effective Properties of a Text Frame

Using Aspose.Slides for Java, you can get effective properties of a Text Frame. For this purpose, the ITextFrameFormatEffectiveData interface was added to Aspose.Slides. It contains effective text frame formatting properties. 

This sample code shows you how to get effective text frame formatting properties:

Presentation pres = new Presentation("Presentation1.pptx");
try {
    IAutoShape shape = (IAutoShape)pres.getSlides().get_Item(0).getShapes().get_Item(0);
    ITextFrameFormatEffectiveData effectiveTextFrameFormat = shape.getTextFrame().getTextFrameFormat().getEffective();

    System.out.println("Anchoring type: " + effectiveTextFrameFormat.getAnchoringType());
    System.out.println("Autofit type: " + effectiveTextFrameFormat.getAutofitType());
    System.out.println("Text vertical type: " + effectiveTextFrameFormat.getTextVerticalType());
    System.out.println("Margins");
    System.out.println("   Left: " + effectiveTextFrameFormat.getMarginLeft());
    System.out.println("   Top: " + effectiveTextFrameFormat.getMarginTop());
    System.out.println("   Right: " + effectiveTextFrameFormat.getMarginRight());
    System.out.println("   Bottom: " + effectiveTextFrameFormat.getMarginBottom());
} finally {
    if (pres != null) pres.dispose();
}

Getting Effective Properties of a Text Style

Using Aspose.Slides for Java, you can get effective properties of Text Style. For this purpose, the ITextStyleEffectiveData interface was added to Aspose.Slides. It contains effective text style properties.

This sample code sample shows you how to get effective text style properties:

Presentation pres = new Presentation("Presentation1.pptx");
try {
    IAutoShape shape = (IAutoShape)pres.getSlides().get_Item(0).getShapes().get_Item(0);
    ITextStyleEffectiveData effectiveTextStyle = shape.getTextFrame().getTextFrameFormat().getTextStyle().getEffective();

    for (int i = 0; i <= 8; i++)
    {
        IParagraphFormatEffectiveData effectiveStyleLevel = effectiveTextStyle.getLevel(i);
        System.out.println("= Effective paragraph formatting for style level #" + i + " =");

        System.out.println("Depth: " + effectiveStyleLevel.getDepth());
        System.out.println("Indent: " + effectiveStyleLevel.getIndent());
        System.out.println("Alignment: " + effectiveStyleLevel.getAlignment());
        System.out.println("Font alignment: " + effectiveStyleLevel.getFontAlignment());
    }
} finally {
    if (pres != null) pres.dispose();
}

Getting Effective Font Height Value

Using Aspose.Slides for Java, you can get effective properties of Font Height. Here, we are providing a code that shows the portion’s effective font height value changing after local font height values are set on different presentation structure levels:

Presentation pres = new Presentation();
try {
    IAutoShape newShape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 400, 75, false);
    newShape.addTextFrame("");
    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().clear();

    IPortion portion0 = new Portion("Sample text with first portion");
    IPortion portion1 = new Portion(" and second portion.");

    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().add(portion0);
    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().add(portion1);

    System.out.println("Effective font height just after creation:");
    System.out.println("Portion #0: " + portion0.getPortionFormat().getEffective().getFontHeight());
    System.out.println("Portion #1: " + portion1.getPortionFormat().getEffective().getFontHeight());

    pres.getDefaultTextStyle().getLevel(0).getDefaultPortionFormat().setFontHeight(24);
    System.out.println("Effective font height after setting entire presentation default font height:");
    System.out.println("Portion #0: " + portion0.getPortionFormat().getEffective().getFontHeight());
    System.out.println("Portion #1: " + portion1.getPortionFormat().getEffective().getFontHeight());

    newShape.getTextFrame().getParagraphs().get_Item(0).getParagraphFormat().getDefaultPortionFormat().setFontHeight(40);
    System.out.println("Effective font height after setting paragraph default font height:");
    System.out.println("Portion #0: " + portion0.getPortionFormat().getEffective().getFontHeight());
    System.out.println("Portion #1: " + portion1.getPortionFormat().getEffective().getFontHeight());

    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().setFontHeight(55);
    System.out.println("Effective font height after setting portion #0 font height:");
    System.out.println("Portion #0: " + portion0.getPortionFormat().getEffective().getFontHeight());
    System.out.println("Portion #1: " + portion1.getPortionFormat().getEffective().getFontHeight());

    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(1).getPortionFormat().setFontHeight(18);
    System.out.println("Effective font height after setting portion #1 font height:");
    System.out.println("Portion #0: " + portion0.getPortionFormat().getEffective().getFontHeight());
    System.out.println("Portion #1: " + portion1.getPortionFormat().getEffective().getFontHeight());

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

Getting Effective Fill Format for Table

Using Aspose.Slides for Java, you can get effective fill formatting for different table logic parts. For this purpose, the ICellFormatEffectiveData interface was added in Aspose.Slides. It contains effective fill formatting properties. Please note this: cell formatting always gets priority over row formatting; row gets priority over column; and column gets priority over the whole table.

Presentation pres = new Presentation("Presentation1.pptx");
try {
    ITable tbl = (ITable)pres.getSlides().get_Item(0).getShapes().get_Item(0);
    ITableFormatEffectiveData tableFormatEffective = tbl.getTableFormat().getEffective();
    IRowFormatEffectiveData rowFormatEffective = tbl.getRows().get_Item(0).getRowFormat().getEffective();
    IColumnFormatEffectiveData columnFormatEffective = tbl.getColumns().get_Item(0).getColumnFormat().getEffective();
    ICellFormatEffectiveData cellFormatEffective = tbl.get_Item(0, 0).getCellFormat().getEffective();

    IFillFormatEffectiveData tableFillFormatEffective = tableFormatEffective.getFillFormat();
    IFillFormatEffectiveData rowFillFormatEffective = rowFormatEffective.getFillFormat();
    IFillFormatEffectiveData columnFillFormatEffective = columnFormatEffective.getFillFormat();
    IFillFormatEffectiveData cellFillFormatEffective = cellFormatEffective.getFillFormat();
} finally {
    if (pres != null) pres.dispose();
}
