问题描述
我在纵向模式下相机应用程序，它来自前端和后端cameras.The问题拍摄照片像拍摄的图像以错误的方式旋转......
I have a camera app in portrait mode which takes pictures from both front and back end cameras.The issue is like the captured images are rotated in a wrong way...
有关preVIEW我用下面的code ....
For preview i have used the following code....
Camera.Parameters parameters = camera.getParameters();
android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo();
android.hardware.Camera.getCameraInfo(defaultCameraId, info);
int rotation = this.getWindowManager().getDefaultDisplay()
.getRotation();
if (Integer.parseInt(Build.VERSION.SDK) >= 8) {
int degrees = 0;
switch (rotation) {
case Surface.ROTATION_0:
degrees = 0;
break;
case Surface.ROTATION_90:
degrees = 90;
break;
case Surface.ROTATION_180:
degrees = 180;
break;
case Surface.ROTATION_270:
degrees = 270;
break;
}
int result;
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
result = (info.orientation + degrees) % 360;
result = (360 - result) % 360; // compensate the mirror
} else { // back-facing
result = (info.orientation - degrees + 360) % 360;
}
camera.setDisplayOrientation(result);
} else {
parameters.set("orientation", "portrait");
}
camera.setParameters(parameters);
不过，拍摄的图像在一个错误的way.i旋转也试图用旋转拍摄的图像 matrix.postRotate（位图）。那太不工作像nexus..I一些设备试图EXIF also.But在这里我有网址，而不是filepath.That不能正常工作。谁能帮助我？
But the captured images are rotated in a wrong way.i have also tried to rotate the captured image using matrix.postRotate(bitmap).That too doesn't work in some devices like nexus..I tried EXIF also.But here i have url instead of filepath.That doesn't work as well. can anyone help me ?
推荐答案
您可以参考以下code。
You can refer below code.
ExifInterface exif = new ExifInterface(SourceFileName); //Since API Level 5
String exifOrientation = exif.getAttribute(ExifInterface.TAG_ORIENTATION);
和同时参考这个链接 http://stackoverflow.com/a/6124375/1441666
