NAME¶
plmap - Plot continental outline in world coordinates.
SYNOPSIS¶
plmap(
mapform,
type,
minlong,
maxlong,
minlat,
maxlat)
DESCRIPTION¶
Plots continental outlines in world coordinates. examples/c/x19c demonstrates
how to use this function to create different projections.
Redacted form: General:
plmap(mapform, type, minlong, maxlong, minlat,
maxlat) F95, Java, Perl/PDL, Python: Not implemented?
This function is used in example 19.
ARGUMENTS¶
- mapform (void (*) (PLINT, PLFLT *, PLFLT *),
input)
- A user supplied function to transform the coordinate
longitudes and latitudes to a plot coordinate system. By using this
transform, we can change from a longitude, latitude coordinate to a polar
stereographic project, for example. Initially, x[0]..[n-1] are the
longitudes and y[0]..y[n-1] are the corresponding latitudes. After the
call to mapform(), x[] and y[] should be replaced by the corresponding
plot coordinates. If no transform is desired, mapform can be replaced by
NULL.
- type (char *, input)
- type is a character string. The value of this parameter
determines the type of background. The possible values are:
"globe" -- continental outlines "usa" -- USA and state
boundaries "cglobe" -- continental outlines and countries
"usaglobe" -- USA, state boundaries and continental outlines
- minlong (PLFLT, input)
- The value of the longitude on the left side of the plot.
The value of minlong must be less than the value of maxlong, and the
quantity maxlong-minlong must be less than or equal to 360.
- maxlong (PLFLT, input)
- The value of the longitude on the right side of the
plot.
- minlat (PLFLT, input)
- The minimum latitude to be plotted on the background. One
can always use -90.0 as the boundary outside the plot window will be
automatically eliminated. However, the program will be faster if one can
reduce the size of the background plotted.
- maxlat (PLFLT, input)
- The maximum latitudes to be plotted on the background. One
can always use 90.0 as the boundary outside the plot window will be
automatically eliminated.
