Description:
|
This function adjusts the start and/or end parameter values of a spline. The parameter values are passed in as pointers so that they may be set individually. A
NULL pointer indicates no change at that end.
|
|
|
Errors:
|
Knot sequences must be strictly increasing, so the new start value must be less than the second knot value, and the new end value must be greater than the penultimate knot value. If this condition is violated at either end, the function returns
FALSE and the curve is left unchanged.
