**NAME**

GCA - Draw a cell array

**DESCRIPTION**

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.
