def w = 400;
def h = 200;
def circle = Circle {
centerX:w/2 centerY:h/2
radius:75
fill:
CustomPaint
{url:"{__DIR__}texture.png"}
stroke:Color.BLACK
strokeWidth:3
};
When the code is executed, it renders a circle that is painted with the textured paint returned
by the
CustomPaint
class as shown in the following screenshot:.
How it works...
The previous code snippet shows how to extend the
Paint
class to create a customized
Paint
class that can be used to fill shapes. In this recipe, we will create class
CustomPaint
to be used as textured paint. The class takes an arbitrary image file and use its content as the
textured paint applied to the shape object. Let's examine how that is done in the code:
F
CustomPaint
class
—is used to create our customized paint, we extend the abstract
class
Paint
. Our class exposes the
url:String
property, which is a value that
contains the URL location of the image to be used as the textured background for
the paint.
F
Function
impl_getPlatformPaint
—this is a required function that must be
implemented when extending the
Paint
class. It is expected to return an
Object
instance that can be used as
Paint
instance.
