[mapserver-users] Masking labels

[Lime, Steve D (DNR)]

This isn't a built-in feature...

If the masking layer has no labels associated with it then you can try setting a parameter called POSTLABELCACHE to TRUE. That will draw the layer in question after the labels have been placed. However that will result in partially obscured labels. Your best bet would be to somehow identify polygons that can be labeled ahead of time, perhaps be intersecting their centroids and your mask. It would be an interesting hack to define a label mask layer or something along those lines to filter labels against before rendering.

Subject: [mapserver-users] Masking labels


Hello,

I have made a mapserver image (see the example). This image consists of 2
layers. The top layers works as a mask over the bottom layer so I only see
the bottom layer where I want it to see.
Unfortunately, the labels of the bottom layer aren't masked. Can somebody
tell me how to do that in one image? When possible, I don't want to see half
labels.
Thanks
