Decoding oned code barcode with zxing from file?

Question

Java

Actually, it is interested in the possibility of decoding not with the help of a camera, but directly with a bitmap. For this I use the code

PlanarYUVLuminanceSource source = new PlanarYUVLuminanceSource(byte[] yuvData,
                                  int dataWidth,
                                  int dataHeight,
                                  int left,
                                  int top,
                                  int width,
                                  int height,
                                  boolean reverseHorizontal)
 BinaryBitmap bitmapBinary = new BinaryBitmap(new HybridBinarizer(source));
 result = reader.decode(bitmapBinary);
 ...

Problems with the parameters passed to the PlanarYUVLuminanceSource constructor, if I understand correctly,
yuvData is our bitmap in byte[], dataWidth and dataHeight are the dimensions of the bitmap, and left, top, width, height are
the Rect parameters, into which the barcode is supposed to fall in the photo (as I understand it, the class is sharpened for use with
a camera). I googled, but there are mostly examples that use either old versions of the zxing library, or
java features that are not available in android. Does anyone have a positive experience with zxing guts?
