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:

var pres = new aspose.slides.Presentation("Presentation1.pptx");
try {
    var shape = pres.getSlides().get_Item(0).getShapes().get_Item(0);
    var localTextFrameFormat = shape.getTextFrame().getTextFrameFormat();
    var effectiveTextFrameFormat = localTextFrameFormat.getEffective();
    var localPortionFormat = shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat();
    var effectivePortionFormat = localPortionFormat.getEffective();
} finally {
    if (pres != null) {
        pres.dispose();
    }
}

Getting Effective Properties of the Camera

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

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

var pres = new aspose.slides.Presentation("Presentation1.pptx");
try {
    var threeDEffectiveData = pres.getSlides().get_Item(0).getShapes().get_Item(0).getThreeDFormat().getEffective();
    console.log("= Effective camera properties =");
    console.log("Type: " + threeDEffectiveData.getCamera().getCameraType());
    console.log("Field of view: " + threeDEffectiveData.getCamera().getFieldOfViewAngle());
    console.log("Zoom: " + threeDEffectiveData.getCamera().getZoom());
} finally {
    if (pres != null) {
        pres.dispose();
    }
}

Getting Effective Properties of Light Rig

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

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

var pres = new aspose.slides.Presentation("Presentation1.pptx");
try {
    var threeDEffectiveData = pres.getSlides().get_Item(0).getShapes().get_Item(0).getThreeDFormat().getEffective();
    console.log("= Effective light rig properties =");
    console.log("Type: " + threeDEffectiveData.getLightRig().getLightType());
    console.log("Direction: " + threeDEffectiveData.getLightRig().getDirection());

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

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

var pres = new aspose.slides.Presentation("Presentation1.pptx");
try {
    var threeDEffectiveData = pres.getSlides().get_Item(0).getShapes().get_Item(0).getThreeDFormat().getEffective();
    console.log("= Effective shape's top face relief properties =");
    console.log("Type: " + threeDEffectiveData.getBevelTop().getBevelType());
    console.log("Width: " + threeDEffectiveData.getBevelTop().getWidth());
    console.log("Height: " + threeDEffectiveData.getBevelTop().getHeight());
} finally {
    if (pres != null) {
        pres.dispose();
    }
}

Getting Effective Properties of a Text Frame

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

try {
    var shape = pres.getSlides().get_Item(0).getShapes().get_Item(0);
    var effectiveTextFrameFormat = shape.getTextFrame().getTextFrameFormat().getEffective();
    console.log("Anchoring type: " + effectiveTextFrameFormat.getAnchoringType());
    console.log("Autofit type: " + effectiveTextFrameFormat.getAutofitType());
    console.log("Text vertical type: " + effectiveTextFrameFormat.getTextVerticalType());
    console.log("Margins");
    console.log("   Left: " + effectiveTextFrameFormat.getMarginLeft());

    for (var i = 0; i <= 8; i++) {
        var effectiveStyleLevel = effectiveTextStyle.getLevel(i);
        console.log(("= Effective paragraph formatting for style level #" + i) + " =");
        console.log("Depth: " + effectiveStyleLevel.getDepth());
        console.log("Indent: " + effectiveStyleLevel.getIndent());

    if (pres != null) {
        pres.dispose();
    }
}

Getting Effective Font Height Value

Using Aspose.Slides for Node.js via 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:

var pres = new aspose.slides.Presentation();
try {
    var newShape = pres.getSlides().get_Item(0).getShapes().addAutoShape(aspose.slides.ShapeType.Rectangle, 100, 100, 400, 75, false);
    newShape.addTextFrame("");
    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().clear();
    var portion0 = new aspose.slides.Portion("Sample text with first portion");
    var portion1 = new aspose.slides.Portion(" and second portion.");
    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().add(portion0);
    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().add(portion1);
    console.log("Effective font height just after creation:");
    console.log("Portion #0: " + portion0.getPortionFormat().getEffective().getFontHeight());
    console.log("Portion #1: " + portion1.getPortionFormat().getEffective().getFontHeight());
    pres.getDefaultTextStyle().getLevel(0).getDefaultPortionFormat().setFontHeight(24);
    console.log("Effective font height after setting entire presentation default font height:");
    console.log("Portion #0: " + portion0.getPortionFormat().getEffective().getFontHeight());
    console.log("Portion #1: " + portion1.getPortionFormat().getEffective().getFontHeight());
    newShape.getTextFrame().getParagraphs().get_Item(0).getParagraphFormat().getDefaultPortionFormat().setFontHeight(40);
    console.log("Effective font height after setting paragraph default font height:");
    console.log("Portion #0: " + portion0.getPortionFormat().getEffective().getFontHeight());
    console.log("Portion #1: " + portion1.getPortionFormat().getEffective().getFontHeight());
    newShape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().setFontHeight(55);

}

Getting Effective Fill Format for Table

Using Aspose.Slides for Node.js via Java, you can get effective fill formatting for different table logic parts. For this purpose, the CellFormatEffectiveData class 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.

var pres = new aspose.slides.Presentation("Presentation1.pptx");
try {
    var tbl = pres.getSlides().get_Item(0).getShapes().get_Item(0);
    var tableFormatEffective = tbl.getTableFormat().getEffective();
    var rowFormatEffective = tbl.getRows().get_Item(0).getRowFormat().getEffective();
    var columnFormatEffective = tbl.getColumns().get_Item(0).getColumnFormat().getEffective();
    var cellFormatEffective = tbl.get_Item(0, 0).getCellFormat().getEffective();
    var tableFillFormatEffective = tableFormatEffective.getFillFormat();
    var rowFillFormatEffective = rowFormatEffective.getFillFormat();
    var columnFillFormatEffective = columnFormatEffective.getFillFormat();
    var cellFillFormatEffective = cellFormatEffective.getFillFormat();
} finally {
    if (pres != null) {
        pres.dispose();
    }
}
