我试着从相机上拍摄一张照片，下面的代码可以工作，但我注意到两个问题，第一个问题是输出的质量与相机预览相比很差，第二个问题是位图变得旋转

public static Bitmap getSourceBitmap(byte[] data, int width, int height, boolean isFrontCamera) {
        YuvImage yuvimage = new YuvImage(data, ImageFormat.NV21, width, height, null);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        yuvimage.compressToJpeg(new Rect(0, 0, width, height), 100, baos);
        byte[] jdata = baos.toByteArray();
        BitmapFactory.Options bitmapFatoryOptions = new BitmapFactory.Options();
        bitmapFatoryOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;
        Bitmap bmp = BitmapFactory.decodeByteArray(jdata, 0, jdata.length, bitmapFatoryOptions);
        return Bitmap.createBitmap(bmp, 0, 0, mWidth, mHeight, m, true);
    }

谢谢您
