Add histogram to Curves tool dialog
Last modified: 2003-12-11 23:35:59 UTC
I've seen a curves dialog in a scanner review that has a greyed histogram in the curves graph. see (http://www.imaging-resource.com/PRODS/LS4K/L40A.HTM) I think this could be a nice enhancement. Of course, the histogram should be for the individual curve selected, red, green, blue, or value.
Yes, that could be a nice enhancement for 1.3.x or later. But this is not trivial, because this would require a new curves widget (in order to be able to display the histogram in the backgroun). Also, if we want the interface to be responsive, then the histograms should probably be computer in the background (idle task) for very large images that could be partially swapped out.
I really like this idea a lot and want to see it happen in 1.3.
Doesn't look like it'll get done. Bumping to 2.0. Dave.
Excuse me, I meant Future. Dave.

Another option would be putting the histogram into a dock, perhaps to the image info. It would update live according to the state of the image. That way it would work across all tools.
The histogram is now a dockable and be used with the Curves tool. It would still be nice to have the histogram embedded in the Curves dialog but it is of lower priority now.
Fixed in CVS: 2003-12-12 Michael Natterer <mitch@gimp.org> * app/widgets/gimphistogramview.[ch]: added a hack that allows to render the histogram in a brighter color. Fixed initial range for views that are not selectable. * app/tools/gimpcurvestool.[ch]: replaced the GtkDrawingArea by a bright GimpHistogramView and render the curves tool controls on top of the histogram. Fixes bug #71633.
