GSWN (Set window) — establishes a window, or rectangular subspace,  of world coordinates to be plotted. Calls to GSWN are  discouraged with NCAR Graphics. Instead, use the SET  subroutine because SET also supports mirror imaging and log  scaling of axes.

Synopsis

CALL GSWN (TRNUM, XMIN, XMAX, YMIN, YMAX)

C-Binding Synopsis

#include <ncarg/gks.h>

void gset_win(Gint tran_num, const Glimit *win_limits);

Description

TRNUM

(Integer, Input) - A normalization transformation  number. The number of available transformations is implementation  specific. In the case of NCAR GKS-0A, two normalization  transformations are provided:

0

Selects the identity transformation in which both the  window and viewport have the range of 0. to 1. in both  coordinate directions. This is the default normalization transformation for  GKS. It is also fixed within GKS; that is, it is illegal to call  GSWN with TRNUM = 0.

1

A normalization transformation in which the window is defined by XMIN  to XMAX and YMIN to YMAX.

XMIN

(Real, Input) - The left horizontal coordinate of the window.  XMIN < XMAX

XMAX

(Real, Input) - The right horizontal coordinate of the window.

YMIN

(Real, Input) - The bottom vertical coordinate of the window. YMIN < YMAX

YMAX

(Real, Input) - The top vertical coordinate of the window.

Access

To use GKS routines, load the NCAR GKS-0A library  ncarg_gks.
