2.9.1 SGTNZU/SGTNZV/SGTNZR

1.

Function

Fills in an area inside a closed polygon in the U/V/R- coordinates. Specifies the tone pattern index at the same time.

2.

Call

CALL SGTNZU(N,UPX,UPY,ITPAT)
CALL SGTNZV(N,VPX,VPY,ITPAT)
CALL SGTNZR(N,RPX,RPY,ITPAT)

3.

Explanation of Parameters

N (I) The length of the array UPX, UPY.

UPX, UPY (R) An array of length N. Gives the (X, Y) coordinates of the points defining a polygon in the UC.

VPX, VPY (R) An array of length N. Gives the (X, Y) coordinates of the points defining a polygon in the VC.

RPX, RPY (R) An array of length N. Gives the (X, Y) coordinates of the points defining a polygon in the RC.

ITPAT (I) Tone pattern index. See SGSTNP.

4.

Notes

(a): N must be larger than 3.
(b): The parameter ITPAT specified here does not change the ITPAT inquired by SGTNU, SGTNV, SGTNR.

`N`	`(I)`	The length of the array `UPX`, `UPY`.
`UPX`, `UPY`	`(R)`	An array of length `N`. Gives the (X, Y) coordinates of the points defining a polygon in the UC.
`VPX`, `VPY`	`(R)`	An array of length `N`. Gives the (X, Y) coordinates of the points defining a polygon in the VC.
`RPX`, `RPY`	`(R)`	An array of length `N`. Gives the (X, Y) coordinates of the points defining a polygon in the RC.
`ITPAT`	`(I)`	Tone pattern index. See `SGSTNP`.
