# 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¶

(Real, Input) - X world coordinate of point 1.
(Real, Input) - Y world coordinate of point 1.
(Real, Input) - X world coordinate of point 2.
(Real, Input) - Y world coordinate of point 2.
(Integer, Input) - X dimension of the color index array CLRIA.
(Integer, Input) - Y dimension of the color index array CLRIA.
(Integer, Input) - The index of the starting column in index array CLRIA.
(Integer, Input) - The index of the starting row in index array CLRIA.
(Integer, Input) - Number of cell elements to draw in the X dimension.
(Integer, Input) - Number of cell elements to draw in the Y dimension.
(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.
