When you set an attribute, you pass in the appropriate
attribute object. For example, to change the paint attribute to a blue-green
gradient fill, you would construct a
GradientPaint object and then
gp = new GradientPaint(0f,0f,blue,0f,30f,green); g2.setPaint(gp);
Graphics2D holds references
to its attribute objects--they are not cloned. If you alter an attribute object
that is part of the
Graphics2D context, you need to call the appropriate
set method to notify the context. Modifying an attribute object
during rendering causes unpredictable behavior.
Graphics2D provides the following general
rendering methods that can be used to draw any geometry primitive, text, or
fill--renders any geometry primitive by filling its interior with the color or pattern specified by the paint attribute.
drawString--renders any text string. The font attribute is used to convert the string to glyphs, which are then filled with the color or pattern specified by the paint attribute.
drawImage--renders the specified image.
Graphics2D supports the
methods for particular shapes, such as
