%DIRECTION RFU 14018 12 STRING
%NET_TRIG_ID String received using ethernet trigger. 14019 32 STRING
%IMAGE_BW Camera image in jpeg format. 14020 IMG-DIM BUFFER

%OCRSCORE Score of the OCR regarding the number plate reading. 14022 4 INT32
All strings are null-terminated.
The values of IMG-DIM for BUFFER data are not necessarily multiples of 4 bytes, yet the occupied buffer space is
always a multiple of 4 bytes, this in order to keep structure alignment. For example: IMG-DIM is 34231 bytes. But
data buffer sent is larger (so as to keep 4 bytes-alignment) and the result is a 34232 bytes image. When using the
IMG-DIM value to skip to next datum of the message, this should not be overlooked.
