for those of you who want to follow the discussion about improvements
to the Levels and Curves tools, here's a list of relevant bug reports
with some comments. I'm adding the user list to the Cc: since feedback
from users would be very helpful at this.
Improve color pickers in Levels tool
I would very much appreciate some feedback on this. The bug report is
suggesting that the current behaviour of the gray point picker is
incorrect. I tend to agree with this argument but I would like to
hear other people's opinions on this.
I don't understand what this report is talking about but perhaps one
of you can enlighten us?
Linear histogram in Levels tool
This one has been addressed in the meantime.
Improve Histogram with Luminance Channel
A luminance channel (is that the correct term at all?) would indeed
be a useful addition. Adding it to the Histogram means adding it to
the Levels and Curves tools as well. This could be a rather trivial
change but it might also turn out to be a lot more complicated then
it seems. I am not entirely sure how much code depends on details of
the GimpHistogramChannel enum.
