I inserted on my App a option to take a photo and save it on a directory.
But when I check the taken photo it appears turned. The horizontal photos appears vertical, and the vertical photos appears horizontal.
how can change my code and automatically rotate the photos?
My code:
if (options[item].equals("Take Photo"))
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
}
...
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
try {
Bitmap bitmap;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(),
bitmapOptions);
int nh = (int) ( bitmap.getHeight() * (612.0 / bitmap.getWidth()) );
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 612, nh, true);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
scaled.compress(Bitmap.CompressFormat.JPEG, 90, stream);
byte [] byte_arr = stream.toByteArray();
String image_str = Base64.encodeBytes(byte_arr);
viewImage.setScaleType(ScaleType.CENTER);
viewImage.setImageBitmap(scaled);
task = new getinfo();
task.execute(image_str);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Phoenix" + File.separator + "default";
f.delete();
OutputStream outFile = null;
File file = new File(path, String.valueOf(System.currentTimeMillis()) + ".jpg");
try {
outFile = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
outFile.flush();
outFile.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
This piece helped me to do the same task
private Bitmap rotateImage(String pathToImage) {
// 1. figure out the amount of degrees
int rotation = getImageRotation();
// 2. rotate matrix by postconcatination
Matrix matrix = new Matrix();
matrix.postRotate(rotation);
// 3. create Bitmap from rotated matrix
Bitmap sourceBitmap = BitmapFactory.decodeFile(pathToImage);
return Bitmap.createBitmap(sourceBitmap, 0, 0, sourceBitmap.getWidth(), sourceBitmap.getHeight(), matrix, true);
