Using intent i captured an image into imageview, but on set it rotates either 90 or 270 . how to restrict this rotation?
Intent i=new Intent(MediaStore.ACTION_IMAGE_CAPTURE); i.putExtra(MediaStore.EXTRA_OUTPUT,Uri.parse("file:///"+mProfile_Image));
startActivityForResult(i, 1);
// Set to imageview
mProfileImage.setImageURI(Uri.parse("file:///"+mProfile_Image));
// here imageview is the path
You don't need to restrict the rotation.
Try the following
Uri imageUri = Uri.parse(path);
String imagePath = path;
int rotate = 0;
// initializing
int dpWidth = 100;
int dpHeight = 100;
try {
getContentResolver().notifyChange(imageUri, null);
File imageFile = new File(imagePath);
ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath());
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
} catch (Exception e) {
e.printStackTrace();
}
dpWidth = (int) ((outMetrics.widthPixels / density) * .75);
dpHeight = (int) ((outMetrics.heightPixels / density) * .75);
Matrix matrix = new Matrix();
matrix.postRotate(rotate);
This will help you show the correct image
Edit
This code is not used to rotate the image permanently. So whenever you want to show image in inmageView just rotate and add.
Edit 1
Use this to set image in imageview
Bitmap bm = BitmapFactory.decodeFile(path);
Bitmap bm = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(),
matrix, true);
imageView.setImageBitmap(bm);
Set orientation of your activity to portrait and give it a try.
<activity
android:name="YourActivityName"
android:screenOrientation="portrait">
</activity>

Why images are rotated 90 degree in imageView?? and how to fix it??
All images in gallery are not rotated 90 degree in imageView.
I don't know why some images are rotated 90 degree in imageView.

In some devices, when the camera is launched the orientation would change. In one of my apps, I also faced this issue. To handle this we need to find the orientation and rotate the picture accordingly.
// capture image orientation
public int getCameraPhotoOrientation(Context context, Uri imageUri,
String imagePath) {
int rotate = 0;
try {
context.getContentResolver().notifyChange(imageUri, null);
File imageFile = new File(imagePath);
ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath());
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
Log.i("RotateImage", "Exif orientation: " + orientation);
Log.i("RotateImage", "Rotate value: " + rotate);
} catch (Exception e) {
e.printStackTrace();
}
return rotate;
}
We need to use this integer returned to set the angle for Imageview.
int rotateImage = getCameraPhotoOrientation(this, uriLargeImage,
mediaFile.getAbsolutePath());
articleview.setRotation(rotateImage); // articleview is ImageView
So basically, please find the orientation of the photo as and when it is taken. This is in ExifInterface. Use this information to rotate.
Hope this helps. All the best.
You must set the rotation in the imageview with which the photo was taken:
imageView.setRotation(getCameraPhotoOrientation(filepath));
imageView.setImageURI( Uri.fromFile(filepath));
public static int getCameraPhotoOrientation(String imagePath) {
int rotate = 0;
try {
ExifInterface exif = null;
try {
exif = new ExifInterface(imagePath);
} catch (IOException e1) {
e1.printStackTrace();
}
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION, 0);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 90;
break;
default:
rotate = 0;
}
} catch (Exception e) {
e.printStackTrace();
}
return rotate;
}
As mentioned before it does it automatically. The way I fixed this, was by using this ImageCropper, which counter-rotates it automatically, which is amazing.

So not only do you get to crop and rotate your image, but it fixes the problem too!!

Kotlin answer
use:
implementation 'androidx.exifinterface:exifinterface:VERSION'
Get newest release here: https://developer.android.com/jetpack/androidx/releases/exifinterface
Function:
private fun adjustRotation(file: File): Bitmap{
lateinit var rotatedBitmap: Bitmap
val bitmap = BitmapFactory.decodeFile(file.absolutePath)
val exifInterface = ExifInterface(file)
val orientation: Int = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED)
fun rotateBitmap(source: Bitmap, angle: Int): Bitmap{
val matrix = Matrix()
matrix.postRotate(angle.toFloat())
return Bitmap.createBitmap(source, 0, 0, source.width, source.height, matrix, true)
}
when (orientation){
ExifInterface.ORIENTATION_ROTATE_90 ->
rotatedBitmap = rotateBitmap(bitmap, 90)
ExifInterface.ORIENTATION_ROTATE_180 ->
rotatedBitmap = rotateBitmap(bitmap, 180)
ExifInterface.ORIENTATION_ROTATE_270 ->
rotatedBitmap = rotateBitmap(bitmap, 270)
ExifInterface.ORIENTATION_NORMAL ->
rotatedBitmap = bitmap
else -> rotatedBitmap = bitmap
}
return rotatedBitmap
}
I'm using Exif interface to get the desired orientation of the image but the bitmap I get is just a part of the original picture zoomed out to fit the imageView.How do I get the whole picture(Image Resolution - 2048 x 1152)?
bitmap1 = BitmapFactory.decodeFile(selectedImagePath);
int rotate = 0;
try {
ExifInterface exif = new ExifInterface(selectedImagePath);
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
} catch (Exception e) {
e.printStackTrace();
}
Matrix matrix = new Matrix();
matrix.postRotate(rotate);
bitmap1 = Bitmap.createBitmap(bitmap1, 0, 0, bitmap1.getWidth(),bitmap1.getHeight(), matrix, true);
In my app, the image is captured from the camera and then it displays in a ImageView I've done this approach successfully, but when my image is displayed in Imageview, Image display after rotate. I want to rotate Image and then Display in ImageView. When I click image from front camera then image is display proper with the help of bellow code
Matrix matrix = new Matrix();
matrix.postRotate(90);
Bitmap rotate = Bitmap.createBitmap(scale,0,0,scale.getWidth(),scale.getHeight(),matrix,true);
displayImage.setImageBitmap(rotate);
But when I click from back camera Image will display opposite to front camera.
One more thing when I click image from camera from different angle then image will display in ImageView in different angle.
I use following code in my application.
It works for me...!!!
File mediaFile = new File(mediaPath);
Bitmap bitmap;
if (mediaFile.exists()) {
if (isImage(mediaPath)) {
Bitmap myBitmap = BitmapFactory.decodeFile(mediaFile.getAbsolutePath());
int height = (myBitmap.getHeight() * 512 / myBitmap.getWidth());
Bitmap scale = Bitmap.createScaledBitmap(myBitmap, 512, height, true);
int rotate = 0;
try {
exif = new ExifInterface(mediaFile.getAbsolutePath());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_UNDEFINED);
switch (orientation) {
case ExifInterface.ORIENTATION_NORMAL:
rotate = 0;
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
Matrix matrix = new Matrix();
matrix.postRotate(rotate);
Bitmap rotateBitmap = Bitmap.createBitmap(scale, 0, 0, scale.getWidth(),
scale.getHeight(), matrix, true);
displayImage.setImageBitmap(rotateBitmap);
}
}
public static boolean isImage(String str) {
boolean temp = false;
String[] arr = { ".jpeg", ".jpg", ".png", ".bmp", ".gif" };
for (int i = 0; i < arr.length; i++) {
temp = str.endsWith(arr[i]);
if (temp) {
break;
}
}
return temp;
}
I was facing a problem image capture from camera it was showing image in landscape even though i capture that image in portrait then i found code online. But i think there is some problem with this code it sometimes didn't work (show image in landscape). So what's wrong there
private void adjustImageOrientation()
{
ExifInterface exif;
int rotate = 0;
try
{
exif = new ExifInterface(filepath);
int exifOrientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (exifOrientation)
{
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
}
if (rotate != 0)
{
int w = bitmap.getWidth();
int h = bitmap.getHeight();
// Setting pre rotate
Matrix mtx = new Matrix();
mtx.preRotate(rotate);
// Rotating Bitmap & convert to ARGB_8888, required by tess
try
{
bitmap = Bitmap.createBitmap(bitmap, 0, 0, w, h, mtx, false);
}
catch(OutOfMemoryError e)
{
e.printStackTrace();
//image = Bitmap.createBitmap(image, 0, 0, w/2, h/2, mtx, false);
}
}
}
catch(Exception ex)
{
ex.printStackTrace();
}
// return image.copy(Bitmap.Config.ARGB_8888, true);
}
Capture by My Camera App and Open image by Galerry:
My code open:
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
File file = new File(dt.FileName);
intent.setDataAndType(Uri.fromFile(file), "image/*");
startActivity(intent);
Capture by Standard Camera and Open image by Galerry:
I check Original Image is the same.
How rotate image when open image by Gallery the same Standard Camera?
Use this code to change the image orientation
ExifInterface exif = new ExifInterface(filepath);
int exifOrientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
int rotate = 0;
switch (exifOrientation)
{
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
}
if (rotate != 0)
{
int w = bitmap.getWidth();
int h = bitmap.getHeight();
Matrix mtx = new Matrix();
mtx.preRotate(rotate);
bitmap = Bitmap.createBitmap(bitmap, 0, 0, w, h, mtx, false);
bitmap = bitmap.copy(Bitmap.Config.ARGB_8888, true);
}
