Hmm. There seems no easy way to do this with the current code. Best I can
do is add
an optional filename to the spotread -O option, to automatically save the
spectral
information.
Beta code is here <http://www.argyllcms.com/Argyll_dev_src.zip ;
<http://www.argyllcms.com/Argyll_dev_src.zip>>
if you are in a position to compile it.
Perfect, Graeme. Fast solution there. Just tried it out, works like a charm.
And noticed some other nice fixes in the changelog for 2.02, both the FWA
fixes are relevant and the fix for the graph plot pause. Thanks.
I notice it only works with a .ti3. When trying it with a .sp I get this
/spec2cie -f M2 test.sp test.cie
argyll: Error - No device values, so can't locate white patch for FWA
compensation
Can it be made, so I can force it to believe the .sp is from a white patch,
in case I only have a set of white patch .sp recordings (from different media
whites)?
What I’m currently after is to measure and store paper white .sp with spotread
-O (default settings), then later with spec2cie make simulated variants and
storing those separately, e.g. with changes to simulated instrument
illumination and CIE XYZ illuminant. But as mentioned earlier, the -f switch to
spec2cie won’t accept a .sp input. That would be nice tweak.
And a second tweak, and/or workaround if first isn’t done. If using spotread
with -O <file.sp> for scripting, can I make that store the result of a FWA
compensated reading (as I cannot do it post normal measuring as described
above)? It would be similar to an interactive spotread ’s’ save after having
initialized with ‘A’ and done a reading with ‘a’, then a ’s’ save. Just setting
-I to spotread while using -O doesn’t do it - it stores a regular reading.
Could you make spotread -O do a FWA compensated reading to file when -I is used?
Best regards
Henrik
