Hi All, users often ask me how they can mask parts of their map that are not inside their area of interest. As a quick an fast answer, we developped Mask plugin available on repository. It take selected objects of a polygon layer, and creates a new memory layer, populated with a great rectangle with holes in place of selected objects. We have that way a layer that can be drawn on top of others, masking features.
*We miss two main features: - draw labels only for objects parts inside mask* - *have the ability to generate a mask on the fly when using Atlas tool in Master.* That means, each time Map in composer in Atlas is zoomed on, we would like to generate a map of coverage object. We would also like to be able to generate a mask with buffer options to allow to show beiond strict boundary of mask. *Do others need this?* *Dear dev's, does that sound possible, and not too a CPU killer task? *I guess intersecting all objects on screen with some complex polygons could be hard. What about invalid polygons? Should we suggest simplifying mask polygons on the fly? Please tell me about this, I would be happy to fund this If everybody agrees with that need and implementation. -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Let-s-discuss-on-a-Mask-feature-tp5021391.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
