Description:
This function applies a
Mapping to transform the coordinates of a
set of points in one dimension.
Synopsis
void astTran1( AstMapping
this,
int npoint, const double xin[], int forward, double xout[] )
Parameters:
this
Pointer to the Mapping to be applied.
npoint
The number of points to be
transformed.
xin
An array of "
npoint"
coordinate values for the input
(untransformed) points.
forward
A non-zero value indicates that the Mapping’
s
forward coordinate transformation is to be applied, while a zero value indicates that
the inverse transformation should be used.
xout
An array (with "
npoint"
elements)
into which the coordinates of the output (transformed) points will be written.
