TDPLCH - Draw a character string at a specified position in the
plane of the reference parallelogram.
CALL TDPLCH (XPOS, YPOS, CHRS, SIZE, ANGD, CNTR)
#include <ncarg/ncargC.h>
void c_tdplch(float xpos, float ypos, char *chrs, float size,
float angd, float cntr)
The arguments of TDPLCH are as follows:
- XPOS and YPOS
- (input expressions of type REAL) - the parallelogram coordinates of a
point relative to which the character string is to be positioned.
- CHRS
- (input, of type CHARACTER) - a string suitable for input to the PLOTCHAR
routine PLCHHQ.
- SIZE
- (an input expression of type REAL) - specifies the width of the characters
to be used as a multiple of the "X" dimension of the reference
parallelogram. If the reference parallelogram is not a square, distortion
of the characters is to be expected: for example, if the reference
parallelogram is twice as wide as it is high, then the same will be true
of characters drawn by TDPLCH.
- ANGD
- (an input expression of type REAL) - specifies the angle, in degrees, at
which the character string is to be drawn relative to the reference
parallelogram (0 => in the direction of positive X, 90 => in the
direction of positive Y, 180 => in the direction of negative X, and so
on).
- CNTR
- (an input expression of type REAL) - specifies how the character string is
to be centered relative to the point (XPOS,YPOS) within the reference
parallelogram. If CNTR = -1, the leading edge of the character string will
be placed at (XPOS,YPOS); if CNTR = 0, the center of the character string
will be placed at (XPOS,YPOS); and if CNTR = +1, the trailing edge of the
character string will be placed at (XPOS,YPOS). Other values may be used,
with the logical results; for example, if CNTR = -.5, the point halfway
between the leading edge and the center of the character string will be
placed at (XPOS,YPOS).
The C-binding argument descriptions are the same as the FORTRAN
argument descriptions.
To use TDPLCH or c_tdplch, load the NCAR Graphics libraries ncarg,
ncarg_gks, and ncarg_c, preferably in that order.
