Flop
The Flop node flops the image left and right. Unlike the Flip node, this does not buffer
the image into memory. 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 Flop node.
MatchMove
For information on the MatchMove node, see “ MatchMove ” on page 740.
Move2D
The Move2D node combines many of the other transform nodes, including Pan, Scale,
Shear, and Rotate. The xCenter and yCenter parameters apply to both scaling and
rotation centers. If you need different centers, you can append a second node (Move2D,
Rotate, or Scale) and switch scaling or rotation to that node. This does not cost you any
process time, because Shake concatenates neighboring transforms into one big
transform. Therefore, you lose neither quality nor calculation time.
Also, Shake’s Infinite Workspace comes into play when you have two transforms
together. (For example, one transform rotates the image, and the second transform
rotates the image back, without clipping the corners.) However, in terms of workflow,
when you pan around small elements that are later composited on larger resolution
backgrounds, you do not have to crop your small elements out to create a larger space.
Parameters
This node displays the following controls in the Parameters tab:
xPan, yPan
These values let you move the image horizontally and vertically. 0, 0 represents the
center of the frame, and the xPan and yPan sliders allow adjustments up to plus or
minus the total width and height of the image frame.
angle
Lets you rotate the image around its center point. The slider allows adjustments plus or
minus 360 degrees, but you can enter any value you want into the numeric field.
aspectRatio
This parameter inherits the current value of the defaultAspect global parameter. If
you’re working on a nonsquare pixel or anamorphic image, it is important that this
value is set correctly to avoid unwanted distortion in the image.
xScale, yScale
These parameters let you change the horizontal and vertical scale of the image. By
default, the yScale parameter is locked to the xScale parameter. The sliders let you
adjust the scale of the image from 0 to 4 times the current size, but you can enter any
value into the numeric field.
