.. _auto_curve_invert:

*INVERT THE CURVE BY BY MULTIPLYING THE X BY -1 AND Y BY -1*
============================================================

Inverts a curve by multiplying the X and/or Y values by -1. Use this worker to mirror a curve about the origin, the Y-axis, or the X-axis depending on the selected inversion axis.

   * - Curve 1
     - curve1
     - vector
     - —
     - 
     - Input curve (vector of X/Y pairs) to be inverted; the transformation is applied to the axis selected by `inverttype`.
   * - inverttype
     - inverttype
     - string
     - x
     - 
     - Axis to invert: 'X' multiplies all X values by -1, 'Y' multiplies all Y values by -1, and 'XY' multiplies both axes by -1; defaults to 'X'.

Outputs

   * - curve_invert_output_1
     - curve_invert_output_1
     - vector
     - Resulting curve after the selected axis (X, Y, or both) has been negated; same format and length as the input curve.
