CalcKDForm


Unit:SDL_sline
Class:TSLine
Declaration:procedure CalcKDForm (var k, d: double);

Straight lines may be represented either by the three-parameter model (as it is used natively by this unit)

Ax + By + C = 0,

or, by a two-parameter model specifying slope k and intercept d:

y = kx + d

The method CalcKDForm calculates the parameters k and d of the two-parameter form.

Hint: Please note that ParB must not be zero, otherwise an exception is raised.
