ok, lets resume all of this
i converted the python program in java, its more habitual to manipulate this
language for me
i combined every modes, color, grayscale and bw, all in 75ppp resolution
with 2 different size
*full plate a4+a little margin
*semi sized a5 manually resized in paintbrush scan
for the moment i really dont know how to interpret the 3 to 10 billions
bytes i receive
actual results of the program:
motor do the travel, light goes on yellow for bw and grayscale, and more
lightening blue light in color scan
it give datas, stop at the end in a4, stop at the middle in a5, and then,
return at idle position
results sent and received were compared succesfully with windows xp original
values
heres the work
