[Lprof-users] Unable to select 22-column Pick Template

[Paul W. <pa...@wa...>]

Hi all,

I'm using lprof-1.11.4.1.  I select my IT8 target, which is a 22-column target 
from Wolf Faust.  I select "IT8.7/2 - 22 column picker" for my Pick template.  
I select OK, then Done.  When I got to select the corners on my image file, I 
only get 19 columns of green squares, not 22.

Here is another interesting data point.  If I select the 22-col pick template 
first, then point to the Target directory, the OK button is greyed out.  I 
have to select another Template, before the OK button is clickable.

I'm getting very poor results at 19 columns:

I have chosen CIE XYZ as PCS
Unknown white point (X:1e-314, Y:7e-312, Z:7e-312)
Primaries (x-y): [Red: 0.625415, 0.277302] [Green: 0, 1] [Blue: 0.0833993, 0]

Here are my profile parameters:

Resolution (CLUT points):  33
Profile verbosity: Store anything
Regression:
    Smoothness: 0.500
    Deviation: 1.00e-05
Linear Bradford 

I am hoping that getting the additional 3 columns will improve the dE, 
although I somehow doubt it...

Any help would be appreciated!

[Lprof-users] CVS build

[Kai-Uwe B. <ku...@gm...>]

Hello,

I am missing scons.py from a recent CVS checkout.

README:
$ python scons.py PREFIX=/where/to/install

Is this the way to build LProf? What is needed for a bootstrap?

kind regards
