%%%This patch adds a few compositing nodes :

Vibrance:
Increases the saturation but prevents clipping and oversaturation.

Hue Chroma Luminance:
Adds a Hue Chroma Luminance control,separation,combination nodes.
The HCL Colorspace is similar in spirit to the HSV, but is based on the Lab Colorspace, giving more natural results.

Pixelize:
Pixelizes the picture. The size of the blocks and the method used to pick the
blocks colors can be changed.

Posterize:
Reduces the number of colors in the picture. Similar to Gimp's posterize filter.

ToonAA:
Anti-Aliasing filter for pictures with a small number of colors. Based on the EPX pixel art upscaling algorithm.

%%%Hi, had a look over you're videos and some comets (note that Im not a compositor!)

  • Vibrance: seems generally useful though while looking at this I was thinking perhaps a saturation curve could be used for the same purpose and give more control?

  • Hue Chroma Luminance: +1, looks very useful, perhaps could be made an option for HSV, not sure about that though.

  • Pixelize: Don't have a strong opinion on this, Could be useful - why not have it :)

  • Posterize: Math -> Round can be used for this, but I didnt compare with you're implementation.

I think it'd be good if you mailed the BF-committers mailing list about the patches you've been working on, sure many people there would be interested.

There are some useful nodes indeed. But the thing is -- they're for old compositor :)

Will port them to new compositor and then commit tho.

Hi, thanks for your patch.

We are undergoing a Tracker Curfew where we are automatically closing old patches.

If you think the patch is still relevant please update and re-submit it. For new features make sure there is a clear design from the user level perspective.
