Hi Nicolas
It's really kind of you to follow this up.
I've put an example data set (raw output from the detector) here:
https://docs.google.com/open?id=0B_tFwWNVPR8jOGJlNTIwZDYtNjdlYS00N2E2LTlmZjMtZTQ1MWU0YmM1OWFl
which I hope you can open. The file has a header containing various
parameters - some to do with data organisation, others experimental...
It starts with:
headSize, ByteOrder, DataType, NbCols, NbRows, epoch, sec, mon, I2,
I1, intens, photo (this is a photdiode count not a photograph :-)),
p1M, p300k, frleon, voltage, current, bpmy, bpmz, byfwhm, bzfwhm,
bintens, T_euro
This is followed by the counts in the channels.
These data are from a silver behenate sample that gives circular rings
around the direct beam (high intensity) position. The part of the
detector in the highest intensity area is protected by a rectangular
beam stop. There are a couple of wires visible leading away from this
area. In these data the direct beam position is off-set from the
centre of the detector.
It ought to look pretty....
thanks again !
best wishes

Dear Halina:
Could you please post an example image somewhere?
For example, it would not suprise me if VIPS/NIP2
http://www.vips.ecs.soton.ac.uk/index.php?title=VIPS or ImageMagick
http://www.imagemagick.org/ could read it right out of the box.
