JavaFx Pattern Fill Shapes

JavaFx allows filling the closed shapes with a color. It is also possible to create an image and use it to fill the closed shapes. JavaFx provides the ImagePattern class which defines how the image pattern paints the target 2d shape. The ImagePattern class needs an Image object and fill rectangle (also called as Anchor Rectangle) definition. In this example, we will explore the ImagePattern class and fill the shapes rectangle and circle.
