Create CUSTOM MENU in Blackberry Example

Here CustomMenu is a class which we create any number of menu and according to the tag value

Blackberry - Rotate an image in any degree

This BitmapRotation works from Blackberry Version 5.0 on-wards.

Do the following steps:

1. Download the zip file from this link: BitmapRotate at down side.

2. Extract and take the ImageManipulator.java from that add to your project;

3. and use this code from this link: RotatingBitmap on Blackberry;

or

take MY code from the below LINK for rotate an image in BB:

BitmapRotate.zip

Otherwise take this code:

1. Download the zip file from this link: BitmapRotate at down side.

2. Extract and take the ImageManipulator.java from that add to your project;

and then in our code:

================== StartUp.java===================



public class StartUp extends UiApplication
{
public static void main(String[] args)
{
StartUp app = new StartUp();
app.enterEventDispatcher();
}

public StartUp()
{
RotateScreen screen = new RotateScreen();
pushScreen(screen);
}

public static void showAlertMessage(final String message)
{
UiApplication.getUiApplication().invokeLater(new Runnable()
{
public void run()
{
Dialog.alert(message);
}
});
}
}

================ RotateScreen.java=============

public class RotateScreen extends MainScreen
{
private BitmapField bitmapField = new BitmapField();
private Bitmap bitmap = Bitmap.getBitmapResource("simple.png");
private ImageManipulator imageManip = new ImageManipulator(bitmap);
private int angle=0;

private VerticalFieldManager vfm = new VerticalFieldManager(VerticalFieldManager.USE_ALL_HEIGHT | VerticalFieldManager.USE_ALL_WIDTH)
{

{
g.setBackgroundColor(Color.GREEN);
g.clear();
}
};
public RotateScreen()
{
super(MainScreen.HORIZONTAL_SCROLLBAR | MainScreen.VERTICAL_SCROLLBAR);
bitmapField.setBitmap(bitmap);
vfm.add(bitmapField);
add(vfm);
addMenuItem(new Restore());
addMenuItem(new Rotate());
addMenuItem(new Continuous());
}

private class Restore extends MenuItem
{
public Restore()
{
super("Restore", 0, 100);
}
public void run()
{
try {
angle = 0;
imageManip.resetTransform();
bitmapField.setBitmap(imageManip.transformAndPaintBitmap());
invalidate();
} catch (Exception e) {
StartUp.showAlertMessage(e.toString());
}

}
}

private class Rotate extends MenuItem {
public Rotate() {
super("Rotate", 0, 100);
}

public void run()
{
try
{
angle +=90;
imageManip.transformByAngle(angle, false, false);
bitmapField.setBitmap(imageManip.transformAndPaintBitmap());
invalidate();
}
catch (Exception e)
{
StartUp.showAlertMessage(e.toString());
}
}
}

private class Continuous extends MenuItem {
public Continuous()
{
super("Continuous", 0, 100);
}

public void run()
{
try
{
new Thread()
{
public void run()
{
for (int angle = 1; angle <= 360; angle++)
{
imageManip.transformByAngle(angle, false, false);
synchronized (UiApplication.getEventLock())
{
bitmapField.setBitmap(imageManip.transformAndPaintBitmap());
invalidate();
}
try
{
Thread.sleep(500);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
}
}
}.start();

} catch (Exception e) {
StartUp.showAlertMessage(e.toString());
}

}
}
}

QRCode Scanning for Blackberry Version 5.0

For this Take the sample code from this following link:

QRCode 5.0

In the above sample application we have QRCode implementation is in "com.alishaik.qrcode.startup";

and if you want to do the this in separately you must add the packages which are provided in the below link:

ZXIng For 5.0  and you and do by your self;

The above ZXIng For 5.0  link nothing but I downloaded this in the below link and separate the packages

http://code.google.com/p/zxing/downloads/list

For Version>5.0 no need to take all these; From 6.0 on wards we have the packages;

I think it helps you alot;

For 6.0 see this below links:
