Save image in original form and without compressing

I want to save the image without compressing it and want to save it in it's original form i.e. when image is compressed the image size decreases and image become small. I am using native camera for this purpose. I am working in android studio. I am making an app in which i am using a camera to save image. But the image is compressed and is very small and very lower quality.
Below is my code for saving image
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
if(requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE)
{
if(resultCode == Activity.RESULT_OK)
{
Bitmap bmp = (Bitmap)data.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] byteArray = stream.toByteArray();
// convert byte array to Bitmap
Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
if(isStoragePermissionGranted())
{
SaveImage(bitmap);
}
}
}else {
switch (requestCode) {
case 1000:
switch (resultCode) {
case Activity.RESULT_OK:
// All required changes were successfully made
getLocation();
break;
case Activity.RESULT_CANCELED:
// The user was asked to change settings, but chose not to
Toast.makeText(this, "Location Service not Enabled", Toast.LENGTH_SHORT).show();
break;
default:
break;
}
break;
}
}
}
private void SaveImage(Bitmap finalBitmap) {
File storageDir = new File (String.valueOf(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)));
String root = storageDir + Environment.getExternalStorageDirectory().getAbsolutePath().toString();
Log.v(LOG_TAG, root);
File myDir = new File(root + "/captured_images");
if (!myDir .exists())
{
myDir .mkdirs();
}
Random generator = new Random();
int n = 1000;
n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
File file = new File(myDir,fname);
try {
file.createNewFile();
MediaScannerConnection.scanFile(getApplicationContext(), new String[] {file.getPath()} , new String[]{"image/*"}, null);
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG,100,out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
Update 1
For more understanding i am putting my onClick method
btn_camera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Check permission for camera
if(ActivityCompat.checkSelfPermission(MainActivity.this, CAMERA)
!= PackageManager.PERMISSION_GRANTED)
{
// Check Permissions Now
// Callback onRequestPermissionsResult interceptado na Activity MainActivity
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{CAMERA},
MainActivity.REQUEST_CAMERA);
}
else {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE );
}
}
});
I searched the solution and found that i can use AndroidBitmapUtil
class so i copy and pasted this class into my project i.e. i created a new class. But i don't know how to use it. Although it is described that i can save image by doing new AndroidBmpUtil().save(bmImage, file);. But again i can't match with my code :(
Any help would be highly appreciated

new AndroidBmpUtil().save(source, sdcardBmpPath);

Open Camera and save image into some specific directory.
solution number 1
private String pictureImagePath = "";
private void openBackCamera() {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = timeStamp + ".jpg";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
pictureImagePath = storageDir.getAbsolutePath() + "/" + imageFileName;
File file = new File(pictureImagePath);
Uri outputFileUri = Uri.fromFile(file);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, 1);}
Handle Image
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
File imgFile = new File(pictureImagePath);
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);
myImage.setImageBitmap(myBitmap);
}
}
solution number 2
I have used the following code and this works perfectly fine for me.
values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "New Picture");
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, PICTURE_RESULT);
and also
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PICTURE_RESULT:
if (requestCode == PICTURE_RESULT)
if (resultCode == Activity.RESULT_OK) {
try {
thumbnail = MediaStore.Images.Media.getBitmap(
getContentResolver(), imageUri);
imgView.setImageBitmap(thumbnail);
imageurl = getRealPathFromURI(imageUri);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
and
public String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

For opening camera use
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "imagename.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
and in your onActivityresult method use
if (requestCode == 1) {
File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("imagename.jpg")) {
f = temp;
break;
}
}
try {
Bitmap bitmap;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(),bitmapOptions);
yourimageview.setImageBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
}

Unable to use intent for CAMERA

In my application ,on clicking Image View i want to start Camera which will capture image and display it in another image view.My code is given below:
//On clicking Camera
iv_camera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
if (data != null) {
Log.e("Result Code", String.valueOf(resultCode));
Bitmap photo = (Bitmap) data.getExtras().get("data");
Uri selectedImageUri = data.getData();
Log.e("ImageUri", String.valueOf(selectedImageUri));
String realPath = getRealPathFromURI(selectedImageUri);
Log.e("Real Path", realPath);
imgProfilePic.setImageBitmap(photo);
}
}
}
//Get real path form Uri
public String getRealPathFromURI(Uri contentUri) {
try {
String[] proj = {MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} catch (Exception e) {
return contentUri.getPath();
}
}
My problem is that ,on some mobiles it is working fine but on some it is not. For example: If i am testing my application using on my phone Yu Yureka having Lollipop ,it is giving me data as null.Also when the orientation changes,application is crashing .Please help me to fix the issue.

In your Manifest file use these permission
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Implement from this Simple Code Example this is my working example code
public void CameraClick(View v) {
Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// creating Dir to save clicked Photo
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/cam_Intent");
myDir.mkdirs();
// save clicked pic to given dir with given name
File file = new File(Environment.getExternalStorageDirectory(),
"/cam_Intent/MyPhoto.jpg");
outPutfileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutfileUri);
startActivityForResult(intent, TAKE_PIC);
}
Bitmap bitmap = null;
#Override
protected void onActivityResult(int requestCode, int resultCode,Intent data)
{
if (requestCode == TAKE_PIC && resultCode==RESULT_OK) {
String uri = outPutfileUri.toString();
Log.e("uri-:", uri);
Toast.makeText(this, outPutfileUri.toString(),Toast.LENGTH_LONG).show();
//Bitmap myBitmap = BitmapFactory.decodeFile(uri);
// mImageView.setImageURI(Uri.parse(uri)); OR drawable make image strechable so try bleow also
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), outPutfileUri);
Drawable d = new BitmapDrawable(getResources(), bitmap);
mImageView.setImageDrawable(d);
} catch (IOException e) {
e.printStackTrace();
}
}
}

Getting path of captured image in Android using camera intent

I have been trying to get path of captured image in order to delete image. Found many answers on StackOverflow but none of them are working for me. I got the following answer:
private String getLastImagePath() {
final String[] imageColumns = { MediaStore.Images.Media._ID,
MediaStore.Images.Media.DATA };
final String imageOrderBy = MediaStore.Images.Media._ID + " DESC";
Cursor imageCursor = POS.this.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns,
null, null, imageOrderBy);
if (imageCursor.moveToFirst()) {
// int id = imageCursor.getInt(imageCursor
// .getColumnIndex(MediaStore.Images.Media._ID));
String fullPath = imageCursor.getString(imageCursor
.getColumnIndex(MediaStore.Images.Media.DATA));
return fullPath;
} else {
return "";
}
}
This code works in Samsung tab but doesn't work in Lenovo tab and i-ball tab.
So, can anyone help me find another solution to do the same?
Any help will be appreciated. Thank you.
This is my onActivityResult:
if (requestCode == CmsInter.CAMERA_REQUEST && resultCode == RESULT_OK) {
//Bitmap photo = null;
//photo = (Bitmap) data.getExtras().get("data");
String txt = "";
if (im != null) {
String result = "";
//im.setImageBitmap(photo);
im.setTag("2");
int index = im.getId();
String path = getLastImagePath();
try {
bitmap1 = BitmapFactory.decodeFile(path, options);
bitmap = Bitmap.createScaledBitmap(bitmap1, 512, 400, false);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] bytData = baos.toByteArray();
try {
baos.close();
} catch (IOException e) {
e.printStackTrace();
}
result = Base64.encode(bytData);
bytData = null;
} catch (OutOfMemoryError ooM) {
System.out.println("OutOfMemory Exception----->" + ooM);
bitmap1.recycle();
bitmap.recycle();
} finally {
bitmap1.recycle();
bitmap.recycle();
}
}
}

Try like this
Pass Camera Intent like below
Intent intent = new Intent(this);
startActivityForResult(intent, REQ_CAMERA_IMAGE);
And after capturing image Write an OnActivityResult as below
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
// CALL THIS METHOD TO GET THE URI FROM THE BITMAP
Uri tempUri = getImageUri(getApplicationContext(), photo);
// CALL THIS METHOD TO GET THE ACTUAL PATH
File finalFile = new File(getRealPathFromURI(tempUri));
System.out.println(mImageCaptureUri);
}
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
public String getRealPathFromURI(Uri uri) {
String path = "";
if (getContentResolver() != null) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
path = cursor.getString(idx);
cursor.close();
}
}
return path;
}
And check log.
Edit:
Lots of people are asking how to not get a thumbnail. You need to add this code instead for the getImageUri method:
public Uri getImageUri(Context inContext, Bitmap inImage) {
Bitmap OutImage = Bitmap.createScaledBitmap(inImage, 1000, 1000,true);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), OutImage, "Title", null);
return Uri.parse(path);
}
The other method Compresses the file. You can adjust the size by changing the number 1000,1000

There is a solution to create file (on external cache dir or anywhere else) and put this file's uri as output extra to camera intent - this will define path where taken picture will be stored.
Here is an example:
File file;
Uri fileUri;
final int RC_TAKE_PHOTO = 1;
private void takePhoto() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(getActivity().getExternalCacheDir(),
String.valueOf(System.currentTimeMillis()) + ".jpg");
fileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
getActivity().startActivityForResult(intent, RC_TAKE_PHOTO);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_TAKE_PHOTO && resultCode == RESULT_OK) {
//do whatever you need with taken photo using file or fileUri
}
}
}
Then if you don't need the file anymore, you can delete it using file.delete();
By the way, files from cache dir will be removed when user clears app's cache from apps settings.

Try this method to get path of original image captured by camera.
public String getOriginalImagePath() {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getActivity().managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, null, null, null);
int column_index_data = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToLast();
return cursor.getString(column_index_data);
}
This method will return path of the last image captured by camera. So this path would be of original image not of thumbnail bitmap.

Here I updated the sample code in Kotlin. Please note on Nougat and above version Uri.fromFile(file) is not working and it crashes the app for that need to implement FileProvider which is safest way to send files from intent. For implementing this refer this answer or this article
private fun takePhotoFromCamera() {
val isDeviceSupportCamera: Boolean = this.packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)
if (isDeviceSupportCamera) {
val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
file = File(getExternalFilesDir(Environment.DIRECTORY_DOCUMENTS + "/attachments")!!.path,
System.currentTimeMillis().toString() + ".jpg")
// fileUri = Uri.fromFile(file)
fileUri = FileProvider.getUriForFile(this, this.applicationContext.packageName + ".provider", file!!)
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri)
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP) {
takePictureIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
}
startActivityForResult(takePictureIntent, Constants.REQUEST_CODE_IMAGE_CAPTURE)
}
} else {
Toast.makeText(this, this.getString(R.string.camera_not_supported), Toast.LENGTH_SHORT).show()
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == Activity.RESULT_OK) {
if(requestCode == Constants.REQUEST_CODE_IMAGE_CAPTURE) {
realPath = file?.path
//do what ever you want to do
}
}
}

Please refer to Google Documentation:
Camera - Photo Basics

try this
String[] projection = { MediaStore.Images.Media.DATA };
#SuppressWarnings("deprecation")
Cursor cursor = managedQuery(mCapturedImageURI, projection,
null, null, null);
int column_index_data = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
image_path = cursor.getString(column_index_data);
Log.e("path of image from CAMERA......******************.........",
image_path + "");
for capturing image:
String fileName = "temp.jpg";
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
mCapturedImageURI = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
values.clear();

Camera Intent returns no file path

I have a problem with my camera Intent. It saves the pictures to the storage, but it doesn't return the file path to my activity. When i remove the EXTRA_OUTPUT it returns the file path, but then the images have just a very small size. Is there any solution to get the pictures with original size without using EXTRA_OUTPUT?
Here is my code:
public void onClick(View arg0) {
switch (arg0.getId()) {
case R.id.btnImageCapture:
preinsertedUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, new ContentValues());
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, preinsertedUri);
startActivityForResult(intent, OPEN_CAMERA);
break;
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode){
case OPEN_CAMERA:
if (resultCode == RESULT_OK && data != null) {
Uri imageUri = null;
imageUri = data.getData();
if(imageUri == null && preinsertedUri != null){
imageUri = preinsertedUri;
}
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(imageUri, filePathColumn, null, null, null);
int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
filePath = cursor.getString(columnIndex);
try {
Bitmap photo = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File f = new File(filePath);
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
fo.close();
} catch (IOException e) {
e.printStackTrace();
}
break;
}
}
}

Try this it might help you.
When I capture the photo from camera so I implement a logic using Cursor and iterate the cursor and get the last photo path which is capture from camera.
It give the path of last capture photo from camera.
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST_CODE);
Cursor cursor = getContentResolver().query(Media.EXTERNAL_CONTENT_URI, new String[]{Media.DATA, Media.DATE_ADDED, MediaStore.Images.ImageColumns.ORIENTATION}, Media.DATE_ADDED, null, "date_added ASC");
if(cursor != null && cursor.moveToFirst())
{
do {
uri = Uri.parse(cursor.getString(cursor.getColumnIndex(Media.DATA)));
photoPath = uri.toString();
}while(cursor.moveToNext());
cursor.close();
}

Why i am not able to take image from camera but can able to get image from Gallery in android?

I am using this code to fetch Image from gallery:
fromGalleryButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
canvasPictureDialog.dismiss();
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
//startActivity(intent);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),10);
//finish();
}
});
And to take image from camera i use this code:
private static final int TAKE_PHOTO_CODE = 1;
private void takePhoto(){
final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(this)) );
startActivityForResult(intent, TAKE_PHOTO_CODE);
}
private File getTempFile(Context context){
//it will return /sdcard/image.tmp
//final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName() );
final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName());
if(!path.exists()){
path.mkdir();
}
return new File(path, "image.tmp");
}
And common code for onActivityResult is:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 10 && resultCode == Activity.RESULT_OK) {
Uri contentUri = data.getData();
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
imagePath = cursor.getString(column_index);
//Bitmap croppedImage = BitmapFactory.decodeFile(imagePath);
tempBitmap = BitmapFactory.decodeFile(imagePath);
photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
}
if(resultCode == RESULT_OK && requestCode==TAKE_PHOTO_CODE){
final File file = getTempFile(this);
try {
tempBitmap = Media.getBitmap(getContentResolver(), Uri.fromFile(file) );
photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
// do whatever you want with the bitmap (Resize, Rename, Add To Gallery, etc)
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Now with using this code i am drawing the image on canvas:
if(!(imagePath==null))
{
//tempBitmap = BitmapFactory.decodeFile(imagePath);
//photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
canvas.drawBitmap (photoBitmap,0, 0, null);
}
But with that use, I am able to get Image from gallery but not from the camera. Why ??
Whats wrong in my code ??
Thanks.

Well, I have solve this problem for my own way.
There is a logical mistake. I have taken the if condition on imagePath variable which can not works for the taking image from camera.
I have taken one boolean Variable and set it for Taking Image from Camera and it works for me.
Anyway, Thanks for the Comments and help.
Thanks.
