Ho un metodo per ruotare le immagini, ma ho sempre ricevuto un OutMemoryError, ma le mie immagini nella galleria iare preso dalla macchina fotografica e la larghezza taglia è 5000 ~ dal telefonoAndroid immagine ridimensionare memoria errori
ho ridimensionato foto alla larghezza 1280 e l'altezza 960
mio primo metodo per l'esposizione e l'immagine ridimensionare è
public static Boolean ShowImagesCapture(Context context, Uri PATH_IMAGE, ImageCropView view,int width, int height){
int orientation=0;
Boolean success = true;
try {
Bitmap bitmap =null;
if (Build.VERSION.SDK_INT < 19) {
String selectedImagePath = getPath(PATH_IMAGE,context);
bitmap = BitmapFactory.decodeFile(selectedImagePath);
orientation=GetPhotoOrientation(context,getRealPathFromURI(context,PATH_IMAGE));
}
else {
ParcelFileDescriptor parcelFileDescriptor;
try {
parcelFileDescriptor = context.getContentResolver().openFileDescriptor(PATH_IMAGE, "r");
FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
bitmap = BitmapFactory.decodeFileDescriptor(fileDescriptor);
parcelFileDescriptor.close();
orientation=GetPhotoOrientation(context,getRealPathFromURI(context,PATH_IMAGE));
} catch (Exception e) {
e.printStackTrace();
}
}
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_180:
bitmap=rotateBitmap(bitmap,3,width,height);
view.setImageBitmap(bitmap);
break;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
bitmap=rotateBitmap(bitmap,8,width,height);
view.setImageBitmap(bitmap);
break;
case ExifInterface.ORIENTATION_TRANSVERSE:
break;
case ExifInterface.ORIENTATION_ROTATE_270:
bitmap=rotateBitmap(bitmap,6,width,height);
view.setImageBitmap(bitmap);
break;
default:
view.setImageBitmap(bitmap);
}
bitmap = null;
}
catch (Exception e) {
e.printStackTrace();
success= false;
}
System.gc();
return success;
}
e il mio metodo per la rotazione dell'immagine è
public static Bitmap rotateBitmap(Bitmap bitmap, int orientation,int width,int height) {
try {
Matrix matrix = new Matrix();
switch (orientation) {
case ExifInterface.ORIENTATION_NORMAL:
return bitmap;
case ExifInterface.ORIENTATION_FLIP_HORIZONTAL:
// matrix.setScale(-1, 1);
break;
case ExifInterface.ORIENTATION_ROTATE_180:
matrix.setRotate(180);
break;
case ExifInterface.ORIENTATION_FLIP_VERTICAL:
matrix.setRotate(180);
// matrix.postScale(-1, 1);
break;
case ExifInterface.ORIENTATION_TRANSPOSE:
matrix.setRotate(90);
// matrix.postScale(-1, 1);
break;
case ExifInterface.ORIENTATION_ROTATE_90:
matrix.setRotate(90);
break;
case ExifInterface.ORIENTATION_TRANSVERSE:
matrix.setRotate(-90);
// matrix.postScale(-1, 1);
break;
case ExifInterface.ORIENTATION_ROTATE_270:
matrix.setRotate(-270);
break;
default:
return bitmap;
}
Bitmap bmRotated = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, false);
bitmap.recycle();
return bmRotated;
}
catch (OutOfMemoryError e) {
Log.e(TAG,"Out memory Error");
return null;
}catch (Exception e){
e.printStackTrace();
return null;
}
}
dov'è il mio errore?

metodo yes and .. ruota l'immagine per prima ridimensionare l'immagine per la larghezza e l'altezza dell'immagine bassa e dopo aver ruotato l'immagine grazie! – pedroooo
aggiorno alla soluzione per il codice !! saluti – pedroooo
@pedroooo Nessun problema, felice di averti aiutato =). – josemgu91
