16.24 - Turn 90

Quick Reference to Scripting Command
a=TURN90(MODE[0-3])
Items in CAPS are 0/1 or ranges with more options than just 0/1.
Ranges other than 0/1 are indicated by brackets, such as [0-2].

 Tip:

This operator may be applied directly to a Warp Layer, resulting in a geometric effect that may be removed from the underlying sublayer composite by simply zeroing out the warp or disabling that layer. In addition, the effect may be moved over the underlying sublayer composite without limit.

A visual reminder that this operator is warp-compatible is the small green dot at the upper right of its ICON in the toolbar.


Operation Example

The Turn 90 operation is used to flip an image region or the entire image in 90 degree increments. This tool can be used to rotate any area selection, but it primary strength lies in rotating an entire image. If you need to rotate an area or the entire image by an amount other than these 90 degree increments, you should use the Rotate operation.


Turn 90 Operation Dialog

16.24.1 - Turn 90 Controls

16.24.1.1 - Trends

Operator dialog controls that have a Trend button next to them offer animation functionality. Trend allows you to set that variable over a set of frames. Each frame of the animation can be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Variables that have multiple states can be set to any of a number of values in the trend. Variables that are either on or off can only have an on or off value in the trend. You will notice that the trend graphs have equidistantly spaced vertical lines. Each of these lines represents a frame in the animation. The number of frames can be altered using Sequence controls... in the TimeLine pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames.

16.24.1.2 - 90 Degree Rotation

Each of these radio buttons represents a 90 degree rotation factor. Selecting the 0 degrees button will result in no effect on the selected area. Selecting 90 degrees will rotate the area by 90 degrees. The remaining two settings will rotate the area selection by 180 degrees or 270 degrees. This tool can be used to rotate any area selection, but it primary strength lies in rotating an entire image. If you need to rotate an area or the entire image by an amount other than these 90 degree increments, you should use the Rotate operation.
