Interpolate 1D (G Dataflow)
Resamples an array of pixels from an image using multiple interpolation functions.
Use this node to perform subpixel analysis of pixel profiles in the image.
image in
Reference to the source image.
coordinate points
Array consisting of the spatial coordinates of pixels in the image.
subpixel information
Cluster containing the following parameters for subpixel analysis:
interpolation type
Method used to perform the interpolation.
| Name | Value | Description |
|---|---|---|
| bi-linear | 0 |
Uses linear interpolation in both the x- and y-directions to compute the pixel location |
| quadratic | 1 |
Uses the quadratic formula to compute the pixel location |
| cubic spline | 2 |
Uses cubic splines to compute the pixel location |
subpixel accuracy
Method used to perform the interpolation.
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.
Default: No error
image out
Reference to the source image.
interpolated array
Array that contains the resampled pixel data.
array size
Size of the interpolated array.
error out
Error information.
The node produces this output 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.
