Image Icon Using Canvas Example
This example is used to create the Image on different location using Canvas
class. In this example to create the image we are using following code:
private Image image1, image2, image3;
|
image1 = Image.createImage("/cartoon.png");
image2 = Image.createImage("/girl-8-icon.png");
image3 = Image.createImage("/mancartoon.png");
|
And for draw the image we are using following code of lines:
| g.drawImage(image1, 0, 0, Graphics.TOP | Graphics.LEFT);
g.drawImage(image2, getWidth() / 2, getHeight() / 2, Graphics.HCENTER |
Graphics.VCENTER);
g.drawImage(image3, getWidth(), getHeight(), Graphics.BOTTOM | Graphics.RIGHT);
|
The application is as follows:
Source Code of ImageItemExample2.java
import java.io.IOException;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class ImageItemExample2 extends MIDlet{
private Display display;
public void startApp(){
display = Display.getDisplay(this);
display.setCurrent(new ImageCanvas());
}
public void pauseApp(){}
public void destroyApp(boolean unconditional){
notifyDestroyed();
}
}
class ImageCanvas extends Canvas{
private Image image1, image2, image3;
public ImageCanvas(){
try{
image1 = Image.createImage("/cartoon.png");
image2 = Image.createImage("/girl-8-icon.png");
image3 = Image.createImage("/mancartoon.png");
}catch (IOException e){
throw new RuntimeException("Unable to load Image: "+e);
}
}
public void paint(Graphics g){
g.setGrayScale(255);
g.fillRect(0, 0, getWidth(), getHeight());
g.drawImage(image1, 0, 0, Graphics.TOP | Graphics.LEFT);
g.drawImage(image2, getWidth() / 2, getHeight() / 2, Graphics.HCENTER
| Graphics.VCENTER);
g.drawImage(image3, getWidth(), getHeight(), Graphics.BOTTOM
