How do I get multiline labels if the text is too large to fit in the length of one line (street).
I know "wrap on character", but I need an automatic way to do it.
Analysing the problem again.
Maybe using a variable?
Perhaps here in Rule Properties > "Filter", using some kind of filter?
or in another place...
Lets think, the fluxogram should be something like:
Measure the lenght of line.
Measure the lenght of the text string (not by charaters, but by mm)
Compares the lenght of the text string with lenght of the line (road).
If the lenght of "line" is equal or less than the lenght of "text" label it with "normal" BUT If the lenght of "line" is greater than the lenght of "text" label it with "multiple lines".
Is conditional or variable. But how?
