class QgsMaskIdProvider

%Docstring(signature="appended")
 | 
						|
Allows the creation of mask ids based on the different label layers and
 | 
						|
to give a mask id from a label layer.
 | 
						|
 | 
						|
Some rendering operations may need multiple mask images. This is the
 | 
						|
case for label rendering in which we can have different mask images: one
 | 
						|
different for each labeling rule for instance. Some label layers may
 | 
						|
need to share their mask images, some other need to have distinct mask
 | 
						|
images. Label layers share the same mask image if the set of symbol
 | 
						|
layers they mask is the same.
 | 
						|
 | 
						|
A "mask id" is then associated to each label layer. They are contiguous
 | 
						|
integer numbers starting at 0.
