Parameters
This node displays the following controls in the Parameters tab:
x0, y0, x1, y1, x2, y2, x3, y3
Eight parameters controlling the position of each corner in the corner-pin operation.
xFilter, yFilter
A pop-up menu that lets you pick which method Shake uses to transform the image.
For more information, see “
Filters Within Transform Nodes ” on page 862.
inverseTransform
A button that inverts the transform. In this case, it puts the four corners into the four
coordinates (0, or pinning), or pulls the four coordinates to the corners (1, or
unpinning).
antialiasing
Individual antialiasing. A value of 0 brings out more clarity.
motionBlur
Motion Blur quality level. 0 is no blur, whereas 1 represents standard filtering. For more
speed, use less than 1. This value is multiplied by the global motionBlur parameter.
• shutterTiming: A subparameter of motionBlur used to specify shutter length. 0 is no
blur, whereas 1 represents a whole frame of blur. Note that standard camera blur is
180 degrees, or a value of .5. This value is multiplied by the global shutterTiming
parameter.
• shutterOffset: A subparameter of motionBlur representing the offset from the current
frame at which the blur is calculated. Default is 0; previous frames are less than 0.
useReference
This is to be used to apply motion blur to previously animated elements. See Tutorial 4,
“Working With Expressions,” in the Shake 4 Tutorials.
Crop
For information on the Crop node, see “ Crop ” on page 186.
Fit
For information on the Fit node, see “ Fit ” on page 183.
Flip
The Flip node flips an image upside down. You can also use the Scale or Move2D node
to invert the image by setting the yScale value to -1. There are no parameters for the
Flip node.
Note: Flip (or a yScale of -1 ) forces the buffering of the image into memory.
