Called repeatedly by the routine cpcica as it executes. updates a particular element of a user's cell array. the default version of cpscae may be replaced by the user with a version that does something different.
CALL CPSCAE (ICRA, ICA1, ICAM, ICAN, XCPF, YCPF, XCQF,
+ YCQF, IND1, IND2, ICAF, IAID)
The first eight arguments of CPSCAE describe the user's cell array and are taken directly from the user's call to CPCICA:
(INTEGER array, dimensioned ICA1 by "n", where "n" is greater than or equal to the value of the argument ICAN, input/output) is the user's cell array. Generally speaking, a user version of CPSCAE should only reset the value of the single element ICRA(IND1,IND2).
(INTEGER, input) is the first dimension of the FORTRAN array ICRA, which contains the user's cell array.
(INTEGER, input) is the first dimension of the user's cell array.
(INTEGER, input) is the second dimension of the user's cell array.
(REAL, input) are the coordinates, in the fractional coordinate system, of a point P. P is the point at that corner of the rectangular area into which the cell array maps that corresponds to the cell (1,1).
(REAL, input) are the coordinates, in the fractional coordinate system, of a point Q. Q is the point at that corner of the rectangular area into which the cell array maps that corresponds to the cell (ICAM,ICAN).
(INTEGER, input) are the indices of an element in the cell array that is to be reset.
(INTEGER, input) is the value of the internal parameter 'CAF', which will be a negative integer (because, when 'CAF' is greater than or equal to zero, the routine CPSCAE is not called). Different values of 'CAF' may be used in a user version of CPSCAE to select different schemes for picking color indices.
(INTEGER, input) is the value of the area identifier associated with the midpoint of the cell (IND1,IND2). The four possibilities are as described for the routine CPCICA.
CPSCAE is not called by the user. When a user calls the routine CPCICA and the internal parameter 'CAF' is negative, CPSCAE is called by CPCICA exactly once for each cell in the cell array. The default version of CPSCAE just sets the cell's color index equal to the area identifier associated with the cell, if that area identifier is greater than or equal to zero; otherwise, it does nothing. A user-supplied version of CPSCAE may do something more complicated; for example, it may take into account both the value of the area identifier associated with the cell and the current value of the color index for the cell in determining the new value of the color index for the cell.
To use CPSCAE, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
