Draws a string such that the specified anchor point is aligned to the given (x, y) location, and returns a bounding rectangle for the text.

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).

Returns the bounds of an aligned string.

Parameters:

text - the string (null not permitted).

g2 - the graphics target (null not permitted).

x - the x-coordinate.

y - the y-coordinate.

anchor - the anchor point that will be aligned to (x, y) (null not permitted).

Returns:

The text bounds (never null).

Returns the bounds for the specified text when it is drawn with the left-baseline aligned to the point (x, y).

Parameters:

text - the text (null not permitted).

x - the x-coordinate.

y - the y-coordinate.
