从相机旋转的照片(SAMSUNG设备)

我讨厌这家公司。他们所有的设备都有很多错误。好的问题: 我试图解决愚蠢的问题(我知道存在超过5年) 它从相机拍摄的照片 - 旋转90度。 我有两个设备:

  Nexus 5p and Samsung j2  
  Nexus - work perfect. Everything fine. 
  Samsung - photo rotated

例如:

Photo size - nexus : Portrate : width 1000, height 1900.  Landscape :
width 1900 , height 1000

让我们看看三星设备:

Photo size  - Portrate: width 1900(?????) height - 1000(????)
rotate to landscape : width 1900 height 1000

经过一些测试:如果在三星设备上以横向模式制作照片 - 比一切都好。照片未旋转

如果在PORTRATE制作照片 - 照片旋转90度。 (但是照片的大小与景观一样(可能如何)?

任何人都知道如何解决这个愚蠢的错误?也许任何人都可以告诉我如何检测相机的方向?我使用IntentActivity拍照:

String _path = Environment.getExternalStorageDirectory()
                                    + File.separator + "camera_img.jpg";
                            File file = new File(_path);
                            Uri outputFileUri = Uri.fromFile(file);
                            Intent intent = new Intent(
                                    android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                            intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
                            startActivityForResult(intent, CAMERA_REQUEST);

有任何帮助吗? 我还添加了一个检查器,如果它的三星设备比旋转。但只有在我们以portrate模式创建照片时,旋转才能正常。在景观一切都很好。所以我需要以某种方式检测出哪个方向照片被创建。有人知道吗?

UPD 29.08.2018 大家好,我发现这种方法适用于基于android 8+的三星设备。我没有三星s8(例如)并且无法理解为什么这在那里再次无效。如果有人可以测试并检查为什么这不起作用 - 让我们一起解决这个问题。

我找到了如何修复:它真的很愚蠢而且对我很难

第一步获取活动结果

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {

            String _path = Environment.getExternalStorageDirectory() + File.separator + "TakenFromCamera.jpg";
            String p1 = Environment.getExternalStorageDirectory().toString();
            String fName = "/TakenFromCamera.jpg";
            final int rotation = getImageOrientation(_path);
            File file = resaveBitmap(p1, fName, rotation);
            Bitmap mBitmap = BitmapFactory.decodeFile(_path);

主要修改它:在文件更改之前的getImageOrientation。

1)getImageOrientation(按路径)
2)重新保存文件(如果需要发送到服务器,如果您只需要预览我们可以跳过此步骤)
3)从文件中获取正确的位图

仅预览第1步和第3步,并使用此功能 - 只需旋转位图。

private Bitmap checkRotationFromCamera(Bitmap bitmap, String pathToFile, int rotate) {
        Matrix matrix = new Matrix();
        matrix.postRotate(rotate);
        Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
        return rotatedBitmap;
    }

getImageOrientation

public static int getImageOrientation(String imagePath) {
    int rotate = 0;
    try {
        ExifInterface exif = new ExifInterface(imagePath);
        int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
        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 (IOException e) {
        e.printStackTrace();
    }
    return rotate;
}

和resaveBitmap如果需要

private File resaveBitmap(String path, String filename, int rotation) { //help for fix landscape photos
        String extStorageDirectory = path;
        OutputStream outStream = null;
        File file = new File(filename);
        if (file.exists()) {
            file.delete();
            file = new File(extStorageDirectory, filename);
        }
        try {
            // make a new bitmap from your file
            Bitmap bitmap = BitmapFactory.decodeFile(path + filename);
            bitmap = checkRotationFromCamera(bitmap, path + filename, rotation);
            bitmap = Bitmap.createScaledBitmap(bitmap, (int) ((float) bitmap.getWidth() * 0.3f), (int) ((float) bitmap.getHeight() * 0.3f), false);
            bitmap = Utils.getCircleImage(bitmap);
            outStream = new FileOutputStream(path + filename);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
            outStream.flush();
            outStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return file;
    }

如果要旋转图像但只有字节数组,可以使用:

private byte[] rotationFromCamera(byte[] data) {
    int rotation = Exif.getOrientation(data);
    if(rotation == 0) return data;
    Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length, null);
    Matrix matrix = new Matrix();
    matrix.postRotate(rotation);
    Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    rotatedBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
    return stream.toByteArray();
}

这个exif util来自answer

如果图像很大,这有点慢。

找到了这个here,对我来说是三星S8。

static final String[] CONTENT_ORIENTATION = new String[] {
            MediaStore.Images.ImageColumns.ORIENTATION
    };


public static int getExifOrientation(Context context, Uri uri) {
    ContentResolver contentResolver = context.getContentResolver();
    Cursor cursor = null;
    try {
        String id = DocumentsContract.getDocumentId(uri);
        id = id.split(":")[1];
        cursor = contentResolver.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                CONTENT_ORIENTATION, MediaStore.Images.Media._ID + " = ?", new String[] { id }, null);
        if (cursor == null || !cursor.moveToFirst()) {
            return 0;
        }
        return cursor.getInt(0);
    } catch (RuntimeException ignored) {
        // If the orientation column doesn't exist, assume no rotation.
        return 0;
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
}

当我从图库Intent.ACTION_GET_CONTENT获取图像时,此方法有效。

MediaStore.ACTION_IMAGE_CAPTURE测试了它,并返回0。但是也许我做错了。

您是否自己使用相机API拍照? 如果是这样,您可以获得以下方向: Camera1 API:

let story = self.storyboard?.instantiateViewController(withIdentifier: "SecondViewController")  as! SecondViewController

    UIView.beginAnimations("", context: nil)
    UIView.setAnimationDuration(1.0)
    UIView.setAnimationCurve(UIViewAnimationCurve.easeInOut)
    UIView.setAnimationTransition(UIViewAnimationTransition.flipFromRight, for: (self.navigationController?.view)!, cache: false)
    self.navigationController?.pushViewController(story, animated: true)
    UIView.commitAnimations()

Camera2 API:

CameraInfo cameraInfo = new CameraInfo();
int sensorOrientation = cameraInfo.orientation;

使用Glide lib可以解决问题

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_PICK_PHOTO_FOR_PROFILE && resultCode == RESULT_OK && data != null && data.getData() != null) {
        try {
           Glide.with(this).load(data.getData()).into(mProfileFragment.mProfileImage);
        } catch (Exception e) {
            Utils.handleException(e);
        }
}
