so the threshold can now be based on the GimpHistogramChannel enum.
Add a channel menu to the threshold dialog and a channel argument to
the PDB procedure (which is new in 2.10).
If I hadn't forgotten what the "RGB" channel is supposed to do I would
have implemented the RGB mode in GimpOperationThreshold correctly.
Right now I'm just guessing. Anyone?
They used to be 0..255, inherited from the old gimp_histogram() and
gimp_threshold() procedures. This commit deprecates these old
procedures and changes the ranges in the new gimp_drawable_histogram()
and gimp_drawable_threshold() to double with a 0.0..1.0 range.
Gamma correction refers to correcting how an image is displayed on
various devices. Gamma adjustment is a more general phrase that also
applies to adjusting gamma as a step in image enhancement in a
color-managed workflow.
because it confuses gtk-doc and breaks some links. Also change the
"Index of new symbols in GIMP 2.x" sections to be what seems to be the
modern standard (looked at the GLib and GTK+ docs), and update some
other stuff.
Which contains all the API from the "color" group, but with a
gimp_drawable namespace and with support for high bit depths. The
group is actually a copy of "color" with cruft removed and some API
ported to using float instead of integer API.
Deprecated all "color" functions that already have a ported version in
"drawable_color".
This is unfinished WIP, some functions in "drawable_color" still have
the old API.
