Hi List,
Is there any way to add a second symbol in CSS based on a condition?
So by example
[param1 = value1] {
mark: symbol(circle);
}
[param2 = value2] {
mark(2): symbol(square); /* around the circle */
}
I could define the second rule as:
[param2 = value2] {
mark: symbol(circle), symbol(square); /* around the circle */
}
But in this case I have to know what is the first symbol and it could also
depend on a condition, so the below is not working fine:
* {
mark: symbol(triangle);
}
[param1 = value1] {
mark: symbol(circle);
}
[param2 = value2] {
mark: symbol(circle), symbol(square); /* here I overload the first
symbol without knowing if it is a triangle or circle */
}
I was considering defining the two symbols in the default rule and use
:nth-mark(1) and :nth-mark(2) later but I do not see any was to change the
symbol itself this way only its style.
I know this can be done in SLD, now we are copying the two CSS generated SLD’s
FeatureTypeStyles to one by hand but this is not a nice solution.
I was also considering using the z-index property but could not figure out how
to achieve the above desired behaviour.
Thank you,
Laszlo
