[Qgis-user] Real Mask functionality in QGIS?

[Neumann, Andreas]

Hi Hilpers, 

Ok - so if I understand this correctly you want a on-the-fly clip, not a
mask. Right? 

A mask is only covering/hiding/selectively drawing geometry, but not
changing geometry. A clip is changing the geometry. See also
https://en.wikipedia.org/wiki/Mask_(computing) [1]vs.
http://pro.arcgis.com/en/pro-app/tool-reference/analysis/clip.htm  

A mask is typically just about drawing features not about manipulating
geometries as processing does. 

We need to use precise terms here.
