PWRZI - A character-plotting routine for plotting characters in
three-space when using Isosurface. For a large class of possible positions,
the hidden character problem is solved.
SUBROUTINE PWRZI (X,Y,Z,ID,N,ISIZE,LINE,ITOP,ICNT)
#include <ncarg/ncargC.h>
void c_pwrzi (float x, float y, float z, char *id, int n,
int isize, int line, int itop, int icnt)
- X,Y,Z
- (input expressions of type REAL) are positioning coordinates for the
characters to be drawn. These are floating point numbers in the same
three-space coordinate system as that used in Isosurface.
- ID
- (an input expression of type CHARACTER) is the character string to be
drawn.
- N
- (an input expression of type INTEGER) is the number of characters in
ID.
- ISIZE
- (an input expression of type INTEGER) specifies the size of the characters
to be used:
- If between 0 and 3, ISIZE is 1., 1.5, 2., or 3. times a standard width
equal to 1/128th of the screen width.
- If greater than 3, ISIZE is the character width in plotter address units
(by default, 1/1024th of the screen width).
- LINE
- (an input expression of type INTEGER) specifies the direction in which the
characters are to be written.
+1 = +X
-1 = -X
+2 = +Y
-2 = -Y
+3 = +Z
-3 = -Z
- ITOP
- (an input expression of type INTEGER) specifies the direction from the
center of the first character to the top of the first character (the
potential values for ITOP are the same as those for LINE as given above).
Note that LINE cannot equal ITOP even in absolute value.
- ICNT
- (an input expression of type INTEGER) is the centering option:
- -1
- (X,Y,Z) is the center of the left edge of the first character.
- +0
- (X,Y,Z) is the center of the entire string.
- +1
- (X,Y,Z) is the center of the right edge of the last character.
The C-binding argument descriptions are the same as the FORTRAN
argument descriptions.
Call PWRZI after calling ISOSRF and before calling FRAME.
Use the ncargex command to see the following relevant examples:
tpwrzi, fsrpwrzs.
To use PWRZI or c_pwrzi, load the NCAR Graphics libraries ncarg,
ncarg_gks, and ncarg_c, preferably in that order.
