[Gimp-developer] GIMP and Gamma Correction?

2001-05-21 Thread Shlomi Fish


Why I could not find a Gamma Correction plug-in in GIMP 1.2.x? Is Gamma
Correction patented in the US?

I know there's Equalize, but I don't suppose it always work. I can
personally implement such a plugin. Gamma correction is a very simple
thing. The question is where can I find it if it's already there, and if
not why it isn't there.

Regards,

Shlomi Fish

A more experienced programmer does not make less bugs. He just realizes
what went wrong more quickly.

It's there: Image-Colors-Levels. The middle entry of the Input Values
corresponds to Gamma.


Salut, Sven

There is also the display filter subsystem which was disables for 1.2
because it was not quite finished. However it's a projection-only
thing and doesn't chahge the image.

It *should* be possible to activate it by simply defining DISPLAY_FILTERS
but haven't tried it.

We should IMHO re-enable it in HEAD to avoid bit-rot.
