Discussed here is the cell array output primitive GCA.
Cell array has no attributes.
The cell array output primitive starts with a rectangle specified by
two diagonally opposite 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.

- XP1
- X world coordinate of point 1 (see below).
- YP1
- Y world coordinate of point 1 (see below).
- XP2
- X world coordinate of point 2 (see below).
- YP2
- Y world coordinate of point 2 (see below).
- NXCLR
- X dimension of the color index array CLRIA.
- NYCLR
- Y dimension of the color index array CLRIA.
- IXCLR
- The index of the starting column in index array CLRIA.
- IYCLR
- The index of the starting row in index array CLRIA.
- NXDO
- Number of cell elements to draw in the X dimension.
- NYDO
- Number of cell elements to draw in the Y dimension.
- CLRIA
- An array of color indices dimensioned NXCLR x NYCLR which is
used to determine the color of each cell drawn.
- Defaults:
- none
- Errors:
- 5,
84
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.
