Get Text Location in a Table Cell

Method IPortion.getRect() has been added. This method extends and actually replaces method IPortion.getCoordinates() which is marked as obsolete now. Methods IPortion.getRect() and IParagraph.getRect() can be applied to text within table cells.

The following example shows how those properties work. Let’s say we have a table with some text inside and simple AutoShape nearby.

The code snippet below generates those objects.

Presentation pres = new Presentation();
try
{
    ITable tbl = pres.getSlides().get_Item(0).getShapes().addTable(50, 50, new double[] { 50, 70 }, new double[] { 50, 50, 50 });

    IParagraph paragraph0 = new Paragraph();
    paragraph0.getPortions().add(new Portion("Text "));
    paragraph0.getPortions().add(new Portion("in0"));
    paragraph0.getPortions().add(new Portion(" Cell"));

    IParagraph paragraph1 = new Paragraph();
    paragraph1.setText("On0");

    IParagraph paragraph2 = new Paragraph();
    paragraph2.getPortions().add(new Portion("Hi there "));
    paragraph2.getPortions().add(new Portion("col0"));

    ICell cell = tbl.get_Item(1, 1);
    cell.getTextFrame().getParagraphs().clear();
    cell.getTextFrame().getParagraphs().add(paragraph0);
    cell.getTextFrame().getParagraphs().add(paragraph1);
    cell.getTextFrame().getParagraphs().add(paragraph2);

    IAutoShape autoShape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 400, 100, 60, 120);
    autoShape.getTextFrame().setText("Text in shape");
} finally {
    if (pres != null) pres.dispose();
}

The source code snippet below will add a yellow frame to all paragraphs and blue frame to all portions which contain substring “0”.

1. In the first step, We’re getting coordinates of the left top corner of the table cell.

double x = tbl.getX() + cell.getOffsetX();
double y = tbl.getY() + cell.getOffsetY();

2. In the next step we’re using IParagrap.getRect() and IPortion.getRect() methods in order to add frame to portions and paragraphs.

for (IParagraph para : cell.getTextFrame().getParagraphs())
{
    if (para.getText().equals(""))
        continue;
    Rectangle2D.Float rect = para.getRect();
    IAutoShape shape =
            pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle,
                    rect.getX() + (float)x, rect.getY)( + (float)y, rect.getWidth(), rect.getHeight());
    shape.getFillFormat().setFillType(FillType.NoFill);
    shape.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.YELLOW);
    shape.getLineFormat().getFillFormat().setFillType(FillType.Solid);

    for (IPortion portion : para.getPortions())
    {
        if (portion.getText().contains("0"))
        {
            rect = portion.getRect();
            shape =
                    pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle,
                            rect.getX() + (float)x, rect.getY() + (float)y, rect.getWidth(), rect.getHeight());
            shape.getFillFormat().setFillType(FillType.NoFill);
        }
    }
}

3. Add frame to AutoShape paragraphs.

for (IParagraph para : autoShape.getTextFrame().getParagraphs())
{
    Rectangle2D.Float rect = para.getRect();
    IAutoShape shape =
            pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 
                    (float) (rect.getX() + autoShape.getX()), (float) (rect.getY() + autoShape.getY()), (float) rect.getWidth(), (float) rect.getHeight());
    shape.getFillFormat().setFillType(FillType.NoFill);
    shape.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.YELLOW);
    shape.getLineFormat().getFillFormat().setFillType(FillType.Solid);
}
