Hi Frederic I have checked the nodes to identify any problems with my project (Compositor redesign).
I don't see any issue Vibrance, the HCL nodes and having a separate gain node. The gain function is hidden in the color balance node. Posterize: There is just a small difference between Math round and the Posterize node. But the math round is only based on values, as this one also concerns colors. I + these nodes, but we should be aware that implementing ocio in blender will in the future change the HCL nodes. Pixelize+ToonAA: This is more a question if these should be part of a compositor. Perhaps someone else can answer this. ToonAA: I see some issues as the algorithms normally are used to upscale 2x2 or 3x3 pixels and this node is tends to be implemented as a convolution filter. What are your thoughts about the last two nodes? PS. in your comments you mention pixelprocessor, but don't use it.

I'd like to get this patch reviewed: It adds a few nodes to the compositor : Vibrance: Increases the saturation but prevents clipping and oversaturation. Video: http://frederic.vanderessen.com/videos/node-vibrance.ogv 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, and gives more natural results. Video: http://frederic.vanderessen.com/videos/node-hcl.ogv Gain: Increases or decreases the dynamic range of the picture. Pixelize: Pixelizes the picture. The size of the blocks and the method used to pick the blocks colors can be changed. Video: http://frederic.vanderessen.com/videos/node-pixelize.ogv 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. The patch is in the tracker :http://projects.blender.org/tracker/index.php?func=detail&aid=28386&group_i d=9&atid=127 You can find a Debian Testing 32bit build here :http://frederic.vanderessen.com/blender_builds/blender-nodes.tar.gz Thanks! -Fred. _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers -------------------------------------------------------------------- mail2web.com - Microsoft® Exchange solutions from a leading provider - http://link.mail2web.com/Business/Exchange _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
