如何在android中将编辑后的画布保存为图片的原始图片大小

Bitmap originalBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.original_image);
int originalWidth = originalBitmap.getWidth();
int originalHeight = originalBitmap.getHeight();

Bitmap editedBitmap = Bitmap.createScaledBitmap(originalBitmap, originalWidth, originalHeight, true);

FileOutputStream outputStream;
try {
    outputStream = new FileOutputStream("/path/to/save/image.jpg");
    editedBitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
    outputStream.flush();
    outputStream.close();
} catch (IOException e) {
    e.printStackTrace();
}
