Textures swing

                  Textures in java Swing

  A texture is a bitmap image applied to the surface in computer graphics. Besides colors and gradients, we can fill our graphics shapes with textures.

            URL url3 = ClassLoader.getSystemResource("texture3.png");

            URL url4 = ClassLoader.getSystemResource("texture4.png");

            URL url5 = ClassLoader.getSystemResource("texture5.png");

            URL url6 = ClassLoader.getSystemResource("texture6.png");

            try {

                bimage1 = ImageIO.read(url1);

                bimage2 = ImageIO.read(url2);

                bimage3 = ImageIO.read(url3);

                bimage4 = ImageIO.read(url4);

                bimage5 = ImageIO.read(url5);

            } catch (IOException ioe) {

                ioe.printStackTrace();

            }

            Rectangle rect1 = new Rectangle(0, 0,

                bimage1.getWidth(), bimage1.getHeight());

            Rectangle rect2 = new Rectangle(0, 0,

                bimage2.getWidth(), bimage2.getHeight());

            Rectangle rect3 = new Rectangle(0, 0,

                bimage3.getWidth(), bimage3.getHeight());

            Rectangle rect4 = new Rectangle(0, 0,

                bimage4.getWidth(), bimage4.getHeight());

            Rectangle rect5 = new Rectangle(0, 0,

                bimage5.getWidth(), bimage5.getHeight());

            Rectangle rect6 = new Rectangle(0, 0,

                bimage6.getWidth(), bimage6.getHeight());

            TexturePaint texture1 = new TexturePaint(bimage1, rect1);

            TexturePaint texture2 = new TexturePaint(bimage2, rect2);

            TexturePaint texture3 = new TexturePaint(bimage3, rect3);

            TexturePaint texture4 = new TexturePaint(bimage4, rect4);

            TexturePaint texture5 = new TexturePaint(bimage5, rect5);

            TexturePaint texture6 = new TexturePaint(bimage6, rect6);

            g2d.setPaint(texture1);

            g2d.fillRect(10, 15, 90, 60);

            g2d.setPaint(texture2);

            g2d.fillRect(130, 15, 90, 60);

            g2d.setPaint(texture3);

            g2d.fillRect(250, 15, 90, 60);

            g2d.setPaint(texture4);

            g2d.fillRect(10, 105, 90, 60);

            g2d.setPaint(texture5);

            g2d.fillRect(130, 105, 90, 60);

            g2d.setPaint(texture6);

            g2d.fillRect(250, 105, 90, 60);

    }

    public static void main(String[] args) {

        Textures rects = new Textures();

        JFrame frame = new JFrame("Textures");

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.add(rects);

        frame.setSize(360, 210);

        frame.setLocationRelativeTo(null);

        frame.setVisible(true);

    }

}

In our example, we will draw six rectangles filled with different textures. To work with textures, Java Swing has a TexturePaint class. 

BufferedImage bimage1 = null;

...

URL url1 = ClassLoader.getSystemResource("texture1.png");

...

bimage1 = ImageIO.read(url1);

We read an image into the memory.

Rectangle rect1 = new Rectangle(0, 0,

    bimage1.getWidth(), bimage1.getHeight());

We get the size of the texture image.

 

TexturePaint texture1 = new TexturePaint(bimage1, rect1);

Here we create a TexturePaint object. The parameters are a buffered image and a rectangle of the image. The rectangle is used to anchor and replicate the image. The images are tiled.

g2d.setPaint(texture1);

g2d.fillRect(10, 15, 90, 60);
