Pixelfudger v2.3

Pixelfudger suite by Xavier Bourque
(updated January 2015)

What's new (January 2015)?
- Added new features to PxF_Erode to allow shrinking and growing of the alpha including 'auto' management of unmult/premult.
- Fixed a bug in PxF_Filler where the in-filled area would get white streaks sometimes, often after using a blur on the hole mask.

What's new (November 2014)?
-Fixed a bug that crashed Nuke when paint strokes were edited upstream of PxF_Distort
-Fixed bugs in PxF_Filler and PxF_IDefocus that prevented node internals from being re-built when the user changed the number of iterations.

What's new (August 2012)?
- PxF_IDefocus for variable blur/defocus/convolves.
- Updated 'help' and 'tooltips'.
- Nodes now in fudgetastic brown.

What's new (March 2012)?
- Most nodes have a mask input that should behave like the 'side' input on Nuke nodes.
- PxF_Filler now has a directional control.
- New nodes: PxF_Grain, PxF_Line, PxF_MergeWrap
- Various bug fixes and improvements.

PxF_Bandpass 2.0.3:
Extract detail from an image by subtracting the original image from a blur of itself.
Useful to enhance an image for easier tracking.

PxF_ChromaBlur 2.0.3:
Blur chroma only (i.e. blur in YCbCr colorspace).
Useful to blur chroma artifacts in digital video.

PxF_Distort 2.0.3:
Fake refraction using an 'edge-detected' deformation map.
Useful to simulate glass-like refractions. Can also be used to grow edges on tricky chroma keys.

PxF_Erode 2.0.3:
Erode the edges of an RGBA image by blurring the alpha, applying a gamma to it and doing a 'min' with the original alpha.

PxF_Filler 3.0.2:
Gaussian in-fill with directional control and unlimited number of iterations.
Useful to remove markers and create clean plates.

PxF_Grain 1.0.2:
Standard Nuke grain with a ColorLookup to adjust the response curve by channel.

PxF_HueSat 2.1.2:
Simple hue and saturation adjustment by adding constants to pixel values in HSL colorspace.

PxF_IDefocus 1.0.2:
Variable blur/defocus/convolve based on a control channel.

PxF_KillSpill 2.5.2:
Remove red/green/blue spill.

PxF_Line 1.0:
Technically not a gizmo. Creates a RotoPaint node with a simple 2-point stroke to create an open ended line.

PxF_MergeWrap 1.1.2:
An 'over' with built-in back and front light wrap.

PxF_ScreenClean 2.0.3:
Use a clean plate to clean up blue/red/green screens.
