astNorm

Normalise a set of Frame coordinates

Description:

This function normalises a set of Frame coordinate values which might be unsuitable for display (e.g. may lie outside the expected range) into a set of acceptable values suitable for display.

Synopsis

void astNorm( AstFrame this, double value[] )

Parameters:

this
Pointer to the Frame.
value
An array of double, with one element for each Frame axis (Naxes attribute). Initially, this should contain a set of coordinate values representing a point in the space which the Frame describes. If these values lie outside the expected range for the Frame, they will be replaced with more acceptable (normalised) values. Otherwise, they will be returned unchanged.
