.. _auto_curve_custom_digitizer:

*CUSTOM DIGITIZER*
==================

Resamples (digitizes) an input curve at a custom set of user-specified X coordinates, returning a new curve whose X values match the provided points. Use this worker when you need to extract curve values at arbitrary, non-uniform X locations rather than at the original sampled points.

When to use

Classification: **process**.

Inputs

     - 
     - Input curve (X/Y vector) to be digitized; if omitted the worker expects the curve to be provided via pipeline context.
   * - X-points
     - x_points
     - textarea
     - —
     - 
     - Whitespace- or comma-separated list of X coordinates at which the input curve will be evaluated (interpolated); leave blank only if the desired X points are supplied by an upstream connection.
