Rotate (G Dataflow)

Last Modified: June 25, 2019

Rotates an image.

connector_pane_image
datatype_icon

color replace value

Cluster containing the alpha, red, green, and blue channel values used for filling a color image.

The default is 0 for all channels, resulting in black.

Default: 0

datatype_icon

image src

Reference to the source image.

datatype_icon

image dst

Reference to the destination image.

datatype_icon

angle

Angle to rotate.

Default: 0 degrees

datatype_icon

replace value

Value the node uses to fill pixels in the rotated image that do not have a corresponding pixel in the image src.

Default: 0

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

use bilinear interpolation

Type of interpolation to use to compute the values of the rotated pixels.

True Bilinear interpolation is used.
False Zero-order interpolation is used.

Default: True

datatype_icon

maintain size

Boolean input that specifies whether you want the resulting image to be the same size as the source image.

True Resulting image is the same size as the source image.
False Resulting image size changes to accommodate the image date from the source image.

Default: True

datatype_icon

image dst out

Reference to the destination image.

If image dst is connected, image dst out is the same as image dst. Otherwise, image dst out refers to the image referenced by image src.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
