Re: [Gegl-developer] Clarification about curves and channels?

[Øyvind Kolås <pippin gimp org>]

A different operation would be better, though the operation in
question exists in GIMP and not in GEGL.

This is because the curves op in GIMP is not properly
migrated/implemented to be part of GEGL, it is controlled with
properties on a "configuration object" and thus as-implemented is only
suitable for use internally in GIMP. It is probably better to create a
new component-curve-remap op that is configured with a curve property
in a similar way to curve-contrast; that can be configured similar to
the curves tool in GIMP while also making sure it works well for
values beyond the 0.0-1.0 range. The existing curves op in GIMP will
likely end up disappearing if all ways of configuring it still are
valid.

For now, please file a feature request in the GEGL issue tracker in gitlab.
