Image is getting skewed after resizing android


Hello i am resizing the image after capturing from native camera.. image resizing is working fine but i have only one problem and that is the image is getting skewed after resizing.

here is the code that i am using to resize the image.

 File f = new File(Environment.getExternalStorageDirectory() + File.separator + "Bavel/" + imageName);
 FileOutputStream fos = null;
 try {
    fos = new FileOutputStream(f);
    if (orientation == ExifInterface.ORIENTATION_UNDEFINED) {
        saveByteArray(fos, getBytesFromBitmap(loadedImage));
    } else {
        saveByteArrayWithOrientation(fos, getBytesFromBitmap(loadedImage), orientation);
    }

} catch (FileNotFoundException e) {
    Log.e("Error", "File not found: " + e.getMessage());
} catch (IOException e) {
    Log.e("Error", "File write failure: " + e.getMessage());
}


private void saveByteArray(FileOutputStream fos, byte[] data) throws IOException {
        long time = System.currentTimeMillis();
        fos.write(data);
        Log.e("saveByteArray: %1dms", "" + (System.currentTimeMillis() - time));
    }

private void saveByteArrayWithOrientation(FileOutputStream fos, byte[] data, int orientation) {

        long totalTime = System.currentTimeMillis();
        long time = System.currentTimeMillis();

        Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
        Log.e("decodeByteArray: %1dms", "" + (System.currentTimeMillis() - time));

        time = System.currentTimeMillis();
        if (orientation != 0 && bitmap.getWidth() > bitmap.getHeight()) {
            Matrix matrix = new Matrix();
            matrix.postRotate(orientation);

            int newWidth;
            int newHeight;

            if (bitmap.getWidth() > bitmap.getHeight()) {
                newHeight = Helper.BITMAP_HEIGHT;
                newWidth = Helper.BITMAP_HEIGHT * bitmap.getWidth() / bitmap.getHeight();
            } else {
                newWidth = Helper.BITMAP_HEIGHT;
                newHeight = Helper.BITMAP_HEIGHT * bitmap.getHeight() / bitmap.getWidth();
            }

            bitmap = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, false);
            bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
        }
        time = System.currentTimeMillis();
        bitmap.compress(Bitmap.CompressFormat.JPEG, Helper.COMPRESS_QUALITY, fos);
        Log.d("compress: %1dms", "" + (System.currentTimeMillis() - time));
        Log.d("bitmap height ", "" + bitmap.getHeight());
        Log.d("bitmap witdh ", "" + bitmap.getWidth());

        bitmap.recycle();

        Log.d("saveByte: %1dms", "" + (System.currentTimeMillis() - totalTime));
    }

public byte[] getBytesFromBitmap(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, Helper.COMPRESS_QUALITY, stream);
        return stream.toByteArray();
    }

Here is the output after resizing the image

But i want the out put like this

Please help and thank for help in advance.


Solution

  • I have solved this by using below code. i am adding the answer so it might be helpful to someone else.

    ExifInterface exif = new ExifInterface(imagePath);
    final int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
    File root = new File(Environment.getExternalStorageDirectory(), "/Bavel/");
    if (!root.exists()) {
        root.mkdirs();
    }
    File f = new File(Environment.getExternalStorageDirectory()
            + File.separator + "Bavel/" + imageName);
    resizeNewImage(loadedImage, f, orientation);
    
    
    
    private void resizeNewImage(Bitmap bm, File file, int orientation) {
        try {
            if (bm.getWidth() > bm.getHeight()) {
                int newWidth;
                int newHeight;
    
                if (bm.getWidth() > bm.getHeight()) {
                    newHeight = Helper.BITMAP_HEIGHT;
                    newWidth = Helper.BITMAP_HEIGHT * bm.getWidth() / bm.getHeight();
                } else {
                    newWidth = Helper.BITMAP_HEIGHT;
                    newHeight = Helper.BITMAP_HEIGHT * bm.getHeight() / bm.getWidth();
                }
    
                Matrix matrix = new Matrix();
                switch (orientation) {
                    case ExifInterface.ORIENTATION_NORMAL:
                        matrix.postRotate(90);
                    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);

                        matrix.setRotate(-90);
                        break;
                    default:
                        matrix.postRotate(90);
                }
                bm = Bitmap.createScaledBitmap(bm, newWidth, newHeight, true);
                bm = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true);
    //                file.createNewFile();
                FileOutputStream ostream = new FileOutputStream(file);
                bm.compress(Bitmap.CompressFormat.JPEG, Helper.COMPRESS_QUALITY, ostream);
    
                ostream.close();
            }
    
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
