Get Paragraph and Portion Coordinates in TextFrame

Using Aspose.Slides for Node.js via Java, developers can now get the rectangular coordinates for Paragraph inside paragraphs collection of TextFrame. It also allows you to get the coordinates of portion inside portion collection of a paragraph. In this topic, we are going to demonstrate with the help of an example that how to get the rectangular coordinates for paragraph along with position of portion inside a paragraph.

var shape = pres.getSlides().get_Item(0).getShapes().get_Item(0);
var textFrame = shape.getTextFrame();
for (let i = 0; i < textFrame.getParagraphs().getCount(); i++) {
    const paragraph = textFrame.getParagraphs().get_Item(i);
    for (let j = 0; j < paragraph.getPortions().getCount(); j++) {
        const portion = paragraph.getPortions().get_Item(j);
        var point = portion.getCoordinates();
    }
}

Get Rectangular Coordinates of Paragraph

Using getRect() method developers can get paragraph bounds rectangle.

var pres = new aspose.slides.Presentation("HelloWorld.pptx");
try {
    var shape = pres.getSlides().get_Item(0).getShapes().get_Item(0);
    var textFrame = shape.getTextFrame();
    var rect = textFrame.getParagraphs().get_Item(0).getRect();
    console.log("X: " + rect.x + " Y: " + rect.y + " Width: " + rect.width + " Height: " + rect.height);
} finally {
    if (pres != null) {
        pres.dispose();
    }
}

Get size of paragraph and portion inside table cell text frame

To get the Portion or Paragraph size and coordinates in a table cell text frame, you can use the Portion.getRect and Paragraph.getRect methods.

This sample code demonstrates the described operation:

var pres = new aspose.slides.Presentation("pres.pptx");
try {
    var tbl = pres.getSlides().get_Item(0).getShapes().get_Item(0);
    var cell = tbl.getRows().get_Item(1).get_Item(1);
    var x = tbl.getX() + tbl.getRows().get_Item(1).get_Item(1).getOffsetX();
    var y = tbl.getY() + tbl.getRows().get_Item(1).get_Item(1).getOffsetY();
    
    for (let i = 0; i < cell.getTextFrame().getParagraphs().getCount(); i++) {
        const para = cell.getTextFrame().getParagraphs().get_Item(i);
        if (para.getText() === "") {
            continue;
        }
        var rect = para.getRect();
        var shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(aspose.slides.ShapeType.Rectangle, java.newFloat(rect.getX() + x), java.newFloat(rect.getY() + y), java.newFloat(rect.getWidth()), java.newFloat(rect.getHeight()));
        shape.getFillFormat().setFillType(java.newByte(aspose.slides.FillType.NoFill));
        shape.getLineFormat().getFillFormat().getSolidFillColor().setColor(java.getStaticFieldValue("java.awt.Color", "YELLOW"));
        shape.getLineFormat().getFillFormat().setFillType(java.newByte(aspose.slides.FillType.Solid));
        for (let j = 0; j < para.getPortions().getCount(); j++) {
            const portion = para.getPortions().get_Item(j);
            if (portion.getText().includes("0")) {
                rect = portion.getRect();
                shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(aspose.slides.ShapeType.Rectangle, java.newFloat(rect.getX() + x), java.newFloat(rect.getY() + y), java.newFloat(rect.getWidth()), java.newFloat(rect.getHeight()));
                shape.getFillFormat().setFillType(java.newByte(aspose.slides.FillType.NoFill));
            }
        }
    }
    pres.save("output.pptx", aspose.slides.SaveFormat.Pptx);
} finally {
    if (pres != null) {
        pres.dispose();
    }
