我正在使用android:hardware:camera api来制作定制相机。我已经做了相机,但问题是,从相机拍照后,照片保存在旋转的形式。我使用的相机表面观。
这是在曲面上创建的相机设置功能
最佳答案
try {
File f = new File(imagePath);
ExifInterface exif = new ExifInterface(f.getPath());
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
int angle = 0;
if (orientation == ExifInterface.ORIENTATION_ROTATE_90) {
angle = 90;
} else if (orientation == ExifInterface.ORIENTATION_ROTATE_180) {
angle = 180;
} else if (orientation == ExifInterface.ORIENTATION_ROTATE_270) {
angle = 270;
}
Matrix mat = new Matrix();
mat.postRotate(angle);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2;
Bitmap bmp = BitmapFactory.decodeStream(new FileInputStream(f),
null, options);
bitmap = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),
bmp.getHeight(), mat, true);
ByteArrayOutputStream outstudentstreamOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100,
outstudentstreamOutputStream);
imageView.setImageBitmap(bitmap);
} catch (IOException e) {
Log.w("TAG", "-- Error in setting image");
} catch (OutOfMemoryError oom) {
Log.w("TAG", "-- OOM Error in setting image");
}
在从相机捕获图像并旋转后尝试此操作。
