This documentation is for version 1.0 of DirBlur (net.sf.openfx.DirBlur).
Apply directional blur to an image.
This plugin concatenates transforms upstream.

Parameter / script name | Type | Default | Function |
---|---|---|---|
Translate / translate |
Double | x: 0 y: 0 | Translation along the x and y axes in pixels. Can also be adjusted by clicking and dragging the center handle in the Viewer. |
Rotate / rotate |
Double | 0 | Rotation angle in degrees around the Center. Can also be adjusted by clicking and dragging the rotation bar in the Viewer. |
Scale / scale |
Double | x: 1 y: 1 | Scale factor along the x and y axes. Can also be adjusted by clicking and dragging the outer circle or the diameter handles in the Viewer. |
Uniform / uniform |
Boolean | Off | Use the X scale for both directions |
Skew X / skewX |
Double | 0 | Skew along the x axis. Can also be adjusted by clicking and dragging the skew bar in the Viewer. |
Skew Y / skewY |
Double | 0 | Skew along the y axis. |
Skew Order / skewOrder |
Choice | XY | The order in which skew transforms are applied: X then Y, or Y then X.
XY
YX
|
Amount / transformAmount |
Double | 1 | Amount of transform to apply. 0 means the transform is identity, 1 means to apply the full transform. |
Center / center |
Double | x: 0.5 y: 0.5 | Center of rotation and scale. |
Reset Center / resetCenter |
Button | Reset the position of the center to the center of the input region of definition | |
Interactive Update / interactive |
Boolean | On | If checked, update the parameter values during interaction with the image viewer, else update the values when pen is released. |
HiDPI / hidpi |
Boolean | Off | Should be checked when the display area is High-DPI (a.k.a Retina). Draws OpenGL overlays twice larger. |
Invert / invert |
Boolean | Off | Invert the transform. |
Filter / filter |
Choice | Cubic | Filtering algorithm - some filters may produce values outside of the initial range (*) or modify the values even if there is no movement (+).
Impulse (impulse): (nearest neighbor / box) Use original values.
Box (box): Integrate the source image over the bounding box of the back-transformed pixel.
Bilinear (bilinear): (tent / triangle) Bilinear interpolation between original values.
Cubic (cubic): (cubic spline) Some smoothing.
Keys (keys): (Catmull-Rom / Hermite spline) Some smoothing, plus minor sharpening (*).
Simon (simon): Some smoothing, plus medium sharpening (*).
Rifman (rifman): Some smoothing, plus significant sharpening (*).
Mitchell (mitchell): Some smoothing, plus blurring to hide pixelation (*)(+).
Parzen (parzen): (cubic B-spline) Greatest smoothing of all filters (+).
Notch (notch): Flat smoothing (which tends to hide moire’ patterns) (+).
|
Clamp / clamp |
Boolean | Off | Clamp filter output within the original range - useful to avoid negative values in mattes |
Black outside / black_outside |
Boolean | Off | Fill the area outside the source image with black |
Motion Blur / motionBlur |
Double | 1 | Quality of motion blur rendering. 0 disables motion blur, 1 is a good value. Increasing this slows down rendering. |
Amount / amount |
Double | 1 | Amount of blur transform to apply. A value of 1 means to apply the full transform range. A value of 0 means to apply no blur at all. Default is 1. |
Centered / centered |
Boolean | Off | When checked, apply directional blur symmetrically around the neutral position. |
Fading / fading |
Double | 0 | Controls the fading function. A value of 1 corresponds to linear fading. A value of 0 disables fading. Default is 0. |
Invert Mask / maskInvert |
Boolean | Off | When checked, the effect is fully applied where the mask is 0. |
Mix / mix |
Double | 1 | Mix factor between the original and the transformed image. |
