label engin settings

[3nids]

Hi all,

When defining the label engine settings, I wonder if the "Show all
labels" option should be a layer property rather than an engine setting.

Indeed, I'd like for some layer to force the labelling, but not for all
of them.

What do you think? Did I miss something?

Greetings,

Denis

 Hi,

 I also agree that it should be a per layer option.

 I believe I discussed this with Marco H. already and he said there are
 some technical (PAL?) issues with trying to do it per Layer only. Maybe
 he can explain it - I don't remember.

 From a user point of view I would welcome a per layer option for
 forcing to draw all labels within a layer.

Indeed it's something that PAL does not currently support. But I agree
that it is sometimes useful to label all features even though that
would produce overlaps.

We could improve PAL to place labels in two steps:
1. label features from layers where all features must be labeled,
without collision detection
2. label features from the rest of layers with usual placement
algorithm, labels from step 1 act as obstacles
