ncl_gca (3) Linux Manual Page

GCA (Cell array) – draws a cell array starting with a rectangle specified by two corner points; this initial rectangle is subdivided into subrectangles by specifying an arbitrary number of divisions in the X and Y directions; each subrectangle (or cell) is assigned a color and drawn with that color.

Synopsis

CALL GCA (XP1, YP1, XP2, YP2, NXCLR, NYCLR, IXCLR, IYCLR, NXDO, NYDO, CLRIA)

C-Binding Synopsis

#include <ncarg/gks.h>

void gcell_array(const Grect *rect, const Gpat_rep *colr_array);

Description

XP1

(Real, Input) – X world coordinate of point 1.

YP1

(Real, Input) – Y world coordinate of point 1.

XP2

(Real, Input) – X world coordinate of point 2.

YP2

(Real, Input) – Y world coordinate of point 2.

NXCLR

(Integer, Input) – X dimension of the color index array CLRIA.

NYCLR

(Integer, Input) – Y dimension of the color index array CLRIA.

IXCLR

(Integer, Input) – The index of the starting column in index array CLRIA.

IYCLR

(Integer, Input) – The index of the starting row in index array CLRIA.

NXDO

(Integer, Input) – Number of cell elements to draw in the X dimension.

NYDO

(Integer, Input) – Number of cell elements to draw in the Y dimension.

CLRIA

(Integer array, Input) – An array of color indices dimensioned NXCLR x NYCLR which is used to determine the color of each cell drawn.

Usage

Points 1 and 2 must be diagonally opposite corner points of a rectangle to be divided into NXDO cells in the X dimension and NYDO cells in the Y dimension.

Access

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