[argyllcms] Re: Scanin Problem using -F option

In order to be able to use the -F option with the scanin command I added the 
following line to
the cht file immediately after the "BOXES 999" line:

Generating a profile using a ti3 file like the one above works flawlessly. 
However, when I use
the -F option the RGB_* and STDEV_* fields in the ti3 file are all set to 0, 
like this:
... BEGIN_DATA_FORMAT SAMPLE_ID XYZ_X XYZ_Y XYZ_Z RGB_R RGB_G RGB_B STDEV_R STDEV_G STDEV_B END_DATA_FORMAT

The symptoms are consistent with the raster being completely blank (R=G=B=0).
If the patches are scanned completely off raster, then they will end up
with nonsense values (-2). It's a puzzle that you say the diagnostic looks ok.

Without having all the files to reproduce the problem, it's hard to say much 
more.

Is there a reason you manually added the fiducial line to the .cht file ?
printarg does this automatically in V0.7 Beta 8.
