The Rotate component rotates the source image around the origin point defined by the Origin X and Origin Y inputs. This is a map component, it can be located in the Transform category on the Components Bar. This component can output HDR colors.
Rotate is a non-seamless component. Its presence in a filter disables the Seamless Tiling checkbox, unless you force-enable it in the Overrides dialog or connect it to so-called “seamlessizer inputs” exclusively. For more information, see Non-Seamless Components.
Source: Map Input (HDR), Required
Provides the source image. This is a required input – in order to make Rotate work, this input must be connected. This input can accept HDR colors.
Specifies the angle of rotation. The value of 0 means no rotation, 0.25 is equivalent to 90 degrees clockwise, -0.25 is 90 degrees counter-clockwise, 0.5 is 180 degrees and 1.0 is the same as a full-circle rotation, 360 degrees. Adding integer numbers to or subtracting them from values between -1 and 1 has no addidional effect: values of -3.5, -1.5, 1.5 and 4.5 all are equivalent to 180 degrees. Since Rotation is a map input, its value can be controlled separately for different image areas by connecting a map component. This input can accept HDR colors.
Origin X and Y: Map Inputs (HDR)
These inputs define the coordinates of the origin point for rotation. The way these coordinates are interpreted is defined by the XY Anchor input. Since Origin X and Origin Y are map inputs, their values can be controlled separately for different image areas by connecting a map component. These inputs can accept HDR colors.
Percentage: Map Input
Serves as a multiplier to Rotation. When Percentage is set to 0, Rotation has no effect. Since Percentage is a map input, its value can be controlled separately for different image areas by connecting a map component to this input.
Determines how the coordinate values supplied by Origin X and Origin Y inputs are interpreted. For more information, see How XY Anchor Works.
When a map component is connected to this input, the number of the selected list item is determined separately for different image areas by the HDR brightness level of the image supplied by that component. The item number is calculated as the brightness level rounded to the nearest integer: the brightness level of 0 to 0.5 corresponds to the first item, the level of 0.5 to 1.5 to the second item, and 1.5 to 2.5 to the third item. Out-of-range values are clipped, which corresponds to the last item of the list.
