Remarks
The following information from the ECMA International Standard ECMA-376 can be useful when working with this class.
Specifies the formula that will be used to calculate the value for a guide. Each formula has a certain number of arguments and a specific set of operations to perform on these arguments in order to generate a value for a guide. There are a total of 17 different formulas available. These are shown below with the usage for each defined.
('*/') - Multiply Divide Formula
Arguments: 3 (fmla="*/ x y z")
Usage: "*/ x y z" = ((x * y) / z) = value of this guide
('+-') - Add Subtract Formula
Arguments: 3 (fmla="+- x y z")
Usage: "+- x y z" = ((x + y) - z) = value of this guide
('+/') - Add Divide Formula
Arguments: 3 (fmla="+/ x y z")
Usage: "+/ x y z" = ((x + y) / z) = value of this guide
('?:') - If Else Formula
Arguments: 3 (fmla="?: x y z")
Usage: "?: x y z" = if (x > 0), then y = value of this guide,
else z = value of this guide
('abs') - Absolute Value Formula
Arguments: 1 (fmla="abs x")
Usage: "abs x" = if (x < 0), then (-1) * x = value of this guide
else x = value of this guide
('at2') - ArcTan Formula
Arguments: 2 (fmla="at2 x y")
Usage: "at2 x y" = arctan(y / x) = value of this guide
('cat2') - Cosine ArcTan Formula
Arguments: 3 (fmla="cat2 x y z")
Usage: "cat2 x y z" = (x*(cos(arctan(z / y))) = value of this guide
('cos') - Cosine Formula
Arguments: 2 (fmla="cos x y")
Usage: "cos x y" = (x * cos( y )) = value of this guide
('max') - Maximum Value Formula
Arguments: 2 (fmla="max x y")
Usage: "max x y" = if (x > y), then x = value of this guide
else y = value of this guide
('min') - Minimum Value Formula
Arguments: 2 (fmla="min x y")
Usage: "min x y" = if (x < y), then x = value of this guide
else y = value of this guide
('mod') - Modulo Formula
Arguments: 3 (fmla="mod x y z")
Usage: "mod x y z" = sqrt(x^2 + b^2 + c^2) = value of this guide
('pin') - Pin To Formula
Arguments: 3 (fmla="pin x y z")
Usage: "pin x y z" = if (y < x), then x = value of this guide
else if (y > z), then z = value of this guide
else y = value of this guide
('sat2') - Sine ArcTan Formula
Arguments: 3 (fmla="sat2 x y z")
Usage: "sat2 x y z" = (x*sin(arctan(z / y))) = value of this guide
('sin') - Sine Formula
Arguments: 2 (fmla="sin x y")
Usage: "sin x y" = (x * sin( y )) = value of this guide
('sqrt') - Square Root Formula
Arguments: 1 (fmla="sqrt x")
Usage: "sqrt x" = sqrt(x) = value of this guide
('tan') - Tangent Formula
Arguments: 2 (fmla="tan x y")
Usage: "tan x y" = (x * tan( y )) = value of this guide
('val') - Literal Value Formula
Arguments: 1 (fmla="val x")
Usage: "val x" = x = value of this guide
Note Guides that have a literal value formula specified via fmla="val x" above should only be used within the avLst as an adjust value for the shape. However, this is not strictly enforced.
The possible values for this attribute are defined by the ST_GeomGuideFormula simple type.
