GSWN(3NCARG) NCAR GRAPHICS GSWN(3NCARG)

NAME

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.
