Graphics Function: Draws a line between each x,y point in the from-array to each corresponding x,y point in the to-array. Each line is drawn with the specified graphics color and line style.
USE IFQWIN
result = LINETOAREX (loc(fx), loc(fy), loc(tx) loc(ty), loc(C), loc(S), cnt)
fx |
(Input) INTEGER(2). From x viewport coordinate array. |
fy |
(Input) INTEGER(2). From y viewport coordinate array. |
tx |
(Input) INTEGER(2). To x viewport coordinate array. |
ty |
(Input) INTEGER(2). To y viewport coordinate array. |
C |
(Input) INTEGER(4). Color array. |
S |
(Input) INTEGER(4). Style array. |
cnt |
(Input) INTEGER(4). Length of each coordinate array; also the length of the color array and style array. All of the arrays should be the same size. |
The result type is INTEGER(2). The result is a nonzero value if successful; otherwise, zero.
The lines are drawn using the specified graphics colors and line styles, and with the current write mode. The current write mode is set with SETWRITEMODE.
If the color has the Z'80000000' bit set, the color is an RGB color; otherwise, the color is a palette color.
The styles are as follows from wingdi.h:
SOLID 0
DASH 1 /* ------- */
DOT 2 /* ....... */
DASHDOT 3 /* _._._._ */
DASHDOTDOT 4 /* _.._.._ */
NULL 5
