Hi,
I am seeing that for labeling lines, Mapnik is not drawing labels for
placement="line" if the name to be labelled is "longer" than the line
segment. Just in case this is expected behavior, is there a way I can
override it? [For this highest zoom level, I would prefer not nice looking
names to no names].
Here is why I suspect this.
One line feature is not near any other feature. For that feature
a) If I reduce the font size, to reduce the total length of name it works.
b) Or if I remove the placement = line, it works.
c) I have tried allow_overlap min_distance, max_char_angle_Delta, but this
does not seem to help.
I am using Mapnik code that I had downloaded from svn on 2009-07-03.
I am giving below what does not work and what changes make the name appear.
Thanks,
Hemant
