    • drawAlignedString

      public static Rectangle2D drawAlignedString(String text, Graphics2D g2, float x, float y, TextAnchor anchor)
      Draws a string such that the specified anchor point is aligned to the given (x, y) location.
      Parameters:
      text - the text.
      g2 - the graphics device.
      x - the x coordinate (Java 2D).
      y - the y coordinate (Java 2D).
      anchor - the anchor location.
      Returns:
      The text bounds (adjusted for the text position).

    • getTextBounds

      public static Rectangle2D getTextBounds(String text, Graphics2D g2, FontMetrics fm)
      Returns the bounds for the specified text.
      Parameters:
      text - the text (null permitted).
      g2 - the graphics context (not null).
      fm - the font metrics (not null).
      Returns:
      The text bounds (null if the text argument is null).

    • drawRotatedString

      public static void drawRotatedString(String text, Graphics2D g2, float x, float y, TextAnchor textAnchor, double angle, float rotationX, float rotationY)
      Draws a string that is aligned by one anchor point and rotated about another anchor point.
      Parameters:
      text - the text.
      g2 - the graphics device.
      x - the x-coordinate for positioning the text.
      y - the y-coordinate for positioning the text.
      textAnchor - the text anchor.
      angle - the rotation angle.
      rotationX - the x-coordinate for the rotation anchor point.
      rotationY - the y-coordinate for the rotation anchor point.

    • drawRotatedString

      public static void drawRotatedString(String text, Graphics2D g2, float x, float y, TextAnchor textAnchor, double angle, TextAnchor rotationAnchor)
      Draws a string that is aligned by one anchor point and rotated about another anchor point.
      Parameters:
      text - the text.
      g2 - the graphics device.
      x - the x-coordinate for positioning the text.
      y - the y-coordinate for positioning the text.
      textAnchor - the text anchor.
      angle - the rotation angle (in radians).
      rotationAnchor - the rotation anchor.

    • drawRotatedString

      public static void drawRotatedString(String text, Graphics2D g2, double angle, float x, float y)
      A utility method for drawing rotated text.

      A common rotation is -Math.PI/2 which draws text 'vertically' (with the top of the characters on the left).

      Parameters:
      text - the text.
      g2 - the graphics device.
      angle - the angle of the (clockwise) rotation (in radians).
      x - the x-coordinate.
      y - the y-coordinate.

    • drawRotatedString

      public static void drawRotatedString(String text, Graphics2D g2, float textX, float textY, double angle, float rotateX, float rotateY)
      A utility method for drawing rotated text.

      A common rotation is -Math.PI/2 which draws text 'vertically' (with the top of the characters on the left).

      Parameters:
      text - the text.
      g2 - the graphics device.
      textX - the x-coordinate for the text (before rotation).
      textY - the y-coordinate for the text (before rotation).
      angle - the angle of the (clockwise) rotation (in radians).
      rotateX - the point about which the text is rotated.
      rotateY - the point about which the text is rotated.
