Create a WinMap
A Winmap is a linear Mapping which transforms a rectangular window in one coordinate system into a similar window in another coordinate system by scaling and shifting each axis (the window edges being parallel to the coordinate axes).
A WinMap is specified by giving the coordinates of two opposite corners (A and B) of the window in both the input and output coordinate systems.
"
ncoord"
coordinates of corner A of the window in the input
coordinate system. "
ncoord"
coordinates of corner B
of the window in the input coordinate system. "
ncoord"
coordinates of corner A of the window in the output coordinate system. "
ncoord"
coordinates of corner B of the window in the output
coordinate system. "
printf"
format specifiers identified by "
%"
symbols in the
normal way. "
options"
string contains "
%"
format specifiers,
then an optional list of additional arguments may follow it in order to supply
values to be substituted for these specifiers. The rules for supplying these are
identical to those for the astSet function (and for the C "
printf"
function).
A null Object pointer (AST__NULL) will be returned if this function is invoked with the AST error status set, or if it should fail for any reason.
