Hi:
I have a batching issue that I'm hoping Lcms may be able to
resolve. I am a DBA by profession and not a heavy coder (photography
and unique large format printing methods are my avocation).
I have developed a spreadsheet for analyzing target and ramp color
data that largely references hue angle based on L*a*b* readings (not
to be LCh) from my EyeOne that are loaded into the spreadsheet
through Macbeth Key Wizard. I am coding it in OpenOffice Calc VBA in
the Windows environment, and much of the code is simple
transformations and polar/rectangular conversions, etc.
Unfortunately, I am getting into trouble because L*a*b* is not
perceptually uniform, and as I move saturation down a hue angle axis,
I'm getting the usual perceptual color shifts associated with
L*a*b*. I am a grateful visitor of Bruce Lindbloom's site, and have
read his analysis of L*a*b*'s non-perceptual uniformity
issues. Consequently, I desire to employ his Perceptually Uniform
profile in correcting my raw measured data.
I have a number of tools that are capable of returning L*a*b* data
processed through profiles, but the batch methods are for images and
the raw data methods are calculators that have to be manually fed. I
need to get columns of L*a*b* data in my spreadsheet processed
through Bruce's profile by batch methods, and reloaded into the
spreadsheet for VBA processing.
From what I have been reading, Lcms is a library of source code for
app development, which is beyond my expertise. Is there a developed
tool based on Lcms for Windows that I can use to (at the very least)
run through text list files from a command line (or maybe a GUI) and
batch process the data through a profile (Bruce's) so that I can
reload the corrected data back into the spreadsheet?
Any help would be appreciated!
Thanks, Jim
