ncl_gca - Man Page
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
