Interpolates each point in the first band of the input image into the piecewise-linear function specified by the x and y arrays. The x values must be strictly increasing. If an input point is less than the first or greater than the last x value, then the output is specified by the "behavior" argument: "extrapolate" specifies the output value is extrapolated from the two nearest points, "clamp" specifies the output value is taken from the nearest point, "input" specifies the output value is copied from the input, and "mask" specifies the output value is masked.
Usage
Returns
Image.interpolate(x, y, behavior)
Image
Argument
Type
Details
this: image
Image
The image to which the interpolation is applied.
x
List
The x axis (input) values in the piecewise function.
y
List
The y axis (output) values in the piecewise function.
behavior
String, default: "extrapolate"
The behavior for points that are outside of the range of the supplied function. Options are: 'extrapolate', 'clamp', 'mask', or 'input'.
