GSELNT (Select normalization transformation) – selects a predefined or user-defined transformation that maps world coordinates to normalized device coordinates.
Synopsis
CALL GSELNT (TRNUM)C-Binding Synopsis
#include <ncarg/gks.h> void gsel_norm_tran(Gint tran_num);
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.
- 1
- Selects a normalization transformation in which the window and viewport have been defined by calls to GSWN and GSVP.
- 0
Usage
When a normalization transformation is selected, all world coordinate arguments to GKS functions are transformed by it.Access
To use GKS routines, load the NCAR GKS-0A library ncarg_gks.See Also
