astMatchAxes

Find any corresponding axes in two Frames

Description:

This function looks for corresponding axes within two supplied Frames. An array of integers is returned that contains an element for each axis in the second supplied Frame. An element in this array will be set to zero if the associated axis within the second Frame has no corresponding axis within the first Frame. Otherwise, it will be set to the index (a non-zero positive integer) of the corresponding axis within the first supplied Frame.

Synopsis

void astMatchAxes( AstFrame frm1, AstFrame frm2, int axes )

Parameters:

frm1
Pointer to the first Frame.
frm2
Pointer to the second Frame.
axes
Pointer to an integer array in which to return the indices of the axes (within the first Frame) that correspond to each axis within the second Frame. Axis indices start at 1. A value of zero will be stored in the returned array for each axis in the second Frame that has no corresponding axis in the first Frame.

The number of elements in this array must be greater than or equal to the number of axes in the second Frame.

Applicability

Frame
This function applies to all Frames.
