VC12FndXPnt
V = Variables
C = Calculation functions
* = Replaces the function VC11FndXPnt
The VC12FndXPnt function calculates the x-coordinate of a point to a line with 2 points of the straight line (X1-Y1 and X2-Y2) and the y-coordinate of the point (YP).
IMPLEMENTATION
VC12FndXPnt (pointX1, pointY1, pointX2, pointY2, pointXP, pointYP)
Parameters:
| IN/OUT | VARIABLE TYPE | EXAMPLE NAME | DIM | |
|---|---|---|---|---|
| IN | SYSTEM or GLOBAL | pointX1 | L/S | Point X1 of the straight line (Abscissa X1) |
| IN | SYSTEM or GLOBAL | pointY1 | L/S | Point Y1 of the straight line (Ordinate Y1) |
| IN | SYSTEM or GLOBAL | pointX2 | L/S | Point X2 of the straight line (Abscissa X2) |
| IN | SYSTEM or GLOBAL | pointY2 | L/S | Point Y2 of the straight line (Ordinate Y2) |
| OUT | SYSTEM or GLOBAL | pointXP | L/S | Point X of the straight line calculated by the function (Unknown abscissa) |
| IN | SYSTEM or GLOBAL | pointYP | L/S | Point Y of the straight line for which you want to calculate the abscissa (X) |
N.B.: pointX1, pointY1, pointY1, pointY2 between them must be the same size (DIM). All parameters must belong to the same type (SYSTEM or GLOBAL).
Example
Execute the calculation when the “gfCalc” flag is set to 1.
IF gfCalc
gfCalc = 0
pointX1 = 100 ;Sets the point values of the straight line
pointY1 = 600
pointX2 = 200
pointY2 = 1200
pointYP = 1000
VC12FndXPnt (pointX1, pointY1, pointX2, pointY2, pointXP, pointYP)
gsAscissaCal = pointXP
ENDIF
DIFFERENCES FROM THE OLD RELEASE
-
(from 10 to 11) Added the possibility to declare parameters “pointXP” and “pointYP” with Long dimension (L)
-
(from 11 to 12) Introduced the possibility to use GLOBAL type parameters
