I think the method would go something like this:
If you can get the endpoints then
for line one x1,y1 and x2,y2
for line two x3,y3 and x4,y4
The formula for a line is y=mx+c
where m is the gradient and c the point where the line crosses the y axis
i) determine the gradient for each of the two lineseg m1=(x1-x2)/(y1-y2)
ii) place the value for m in the line equation and set y to 0, solving c
iii) you should now have an equation for each line
iv) where they intersect x and y are equal, so solve
m(line1)x+c(line1)=m(line2)x+c(line2) giving an x value.
v) replace the x value in one of the line formulas giving a value for y
vi) OPTIONAL - check the x value in iv) in the other line equation which
should give the same y result.
vii) you should now have an x,y value which is the point of intersection.
