[mapserver-users] Label wrapping question

[Dejan Gambin]

Here is my situtation - I can fit max 20 chars in my layout. For me, it seems logical to define maxlength of 20 and not worry any more because this is indeed my maximum, and anything above this must be cut. Since it cuts on the word boundary (by setting wrap character to space), it must should cut before.

Anyway, here are some screen captures. In "before" situation, I had to adjust maxlength (from 20 to 15 to 13) to get good enough result. In "after" situation, I just put maxlength to 20 and it seems ok.

Btw, this is just the proof of concept. I didn't make change for label->encoding part, and also, it currently crashes in certain situation if I have a word in label text longer than maxlength. It should all be revised and modified.

regards, dejan
