Java Foundation Classes in a Nutshell

java.awt.geom.FlatteningPathIterator,animplementation of PathIterator that

appr oximates the curved segments in a given path with multiple line segments.

The

flatness argument to getPathIterator() is a measure of how closely these

line segments must approximate the original curve segments, where smaller values

of

flatness imply a better approximation.

Stroking Lines

One of the new graphic attributes defined by Java 2D is the java.awt.Stroke;itis

set with the

setStroke() method of a Graphics2D object. The Stroke attribute is

used by Java 2D whenever it draws a line. Conceptually, the

Stroke describes the

pen or brush that is used to draw the line: it controls all line-drawing attributes,

such as line width and dash pattern. Java 2D defines a single implementation of

the

Stroke inter face, java.awt.BasicStroke, that is suitable for almost all line

drawing needs.

BasicStroke

A BasicStroke object encapsulates several differ ent line drawing attributes: the

line width, the dash pattern, the end cap style for the line, and the join style for

the line. You specify values for these attributes when you call the

BasicStroke()

constructor. BasicStroke objects are immutable, so that they can be safely cached

and shared. This means, however, that they don’t have

set() methods that allow

you to change the attribute values.

The line-width attribute specifies (obviously) the width of the line. This line width

is measured in ...
