%Docstring(signature="appended")
|
|
A polygon or line-only feature renderer used to render a set of features
|
|
merged (or dissolved) into a single geometry.
|
|
|
|
It is designed on top of another feature renderer, which is called
|
|
"embedded" Most of the methods are then only proxies to the embedded
|
|
renderer. E.g. if the embedded renderer is a categorized renderer, then
|
|
all the matching features for each categorized class will be dissolved
|
|
together. Features from different classes will NOT be dissolved
|
|
together.
