This documentation is for version 1.0 of Transform (net.sf.openfx.TransformPlugin).
Translate / Rotate / Scale a 2D image.
This plugin concatenates transforms.

|Parameter / script name||Type||Default||Function|
||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.|
||Double||0||Rotation angle in degrees around the Center. Can also be adjusted by clicking and dragging the rotation bar in the Viewer.|
||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.|
||Boolean||Off||Use the X scale for both directions|
|Skew X /
||Double||0||Skew along the x axis. Can also be adjusted by clicking and dragging the skew bar in the Viewer.|
|Skew Y /
||Double||0||Skew along the y axis.|
|Skew Order /
The order in which skew transforms are applied: X then Y, or Y then X.
||Double||1||Amount of transform to apply. 0 means the transform is identity, 1 means to apply the full transform.|
||Double||x: 0.5 y: 0.5||Center of rotation and scale.|
|Reset Center /
||Button||Reset the position of the center to the center of the input region of definition|
|Interactive Update /
||Boolean||On||If checked, update the parameter values during interaction with the image viewer, else update the values when pen is released.|
||Boolean||Off||Should be checked when the display area is High-DPI (a.k.a Retina). Draws OpenGL overlays twice larger.|
||Boolean||Off||Invert the transform.|
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) (+).
||Boolean||Off||Clamp filter output within the original range - useful to avoid negative values in mattes|
|Black outside /
||Boolean||On||Fill the area outside the source image with black|
|Motion Blur /
||Double||0||Quality of motion blur rendering. 0 disables motion blur, 1 is a good value. Increasing this slows down rendering.|
|Directional Blur Mode /
||Boolean||Off||Motion blur is computed from the original image to the transformed image, each parameter being interpolated linearly. The motionBlur parameter must be set to a nonzero value, and the blackOutside parameter may have an important effect on the result.|
||Double||0.5||Controls how long (in frames) the shutter should remain open.|
|Shutter Offset /
Controls when the shutter should be open/closed. Ignored if there is no motion blur (i.e. shutter=0 or motionBlur=0).
Centered (centered): Centers the shutter around the frame (from t-shutter/2 to t+shutter/2)
Start (start): Open the shutter at the frame (from t to t+shutter)
End (end): Close the shutter at the frame (from t-shutter to t)
Custom (custom): Open the shutter at t+shuttercustomoffset (from t+shuttercustomoffset to t+shuttercustomoffset+shutter)
|Custom Offset /
||Double||0||When custom is selected, the shutter is open at current time plus this offset (in frames). Ignored if there is no motion blur (i.e. shutter=0 or motionBlur=0).|
