Method Detail

getEnclosingShape

public Shape getEnclosingShape()

Returns a shape that encloses the text on the page. The shape's coordinate system is in 'display' coordinates: The origin of the coordinates are page.getCropBox().getX() and page.getCropBox().getY().

Returns:

A Shape that holds the string.

getText

public String getText()

Returns the text string.

Specified by:

getText in interface TextSelection

Returns:

The text.

getQuadrilateral

public Point2D[] getQuadrilateral()

Returns a quadrilateral with the four corners for this text string. The coordinates of the quadrilaterals is in MediaBox space.

Returns:

An array of 4 Point2D object. The points in can be connected by lines in the array order to form the quadrilateral enclosing the text.

getAngle

public double getAngle()

Returns the angle that this text is displayed at on the page.

Returns:

The angle of the text

getQuadrilaterals

public Vector getQuadrilaterals()

Returns a list of quadrilaterals that will enclose the text elements in this object. This method is here to fulfill the TextSelection interface and will always return a Vector with a single element.

Specified by:

getQuadrilaterals in interface TextSelection

Returns:

A list of one quadrilateral - the four around the text

getSelectionShape

public Shape getSelectionShape()

Returns the shape that will enclose the text on the display. This method is here to fulfill the TextSelection interface.

Specified by:

getSelectionShape in interface TextSelection

Returns:

The shape that will enclose the text on the screen.

getPageNumber

public int getPageNumber()
