/**
|
|
* The ivi-layout library supports API set of controlling properties of
|
|
* surface and layer which groups surfaces. A unique ID whose type is integer is
|
|
* required to create surface and layer. With the unique ID, surface and layer
|
|
* are identified to control them. The API set consists of APIs to control
|
|
* properties of surface and layers about the following:
|
|
* - visibility.
|
|
* - opacity.
|
|
* - clipping (x,y,width,height).
|
|
* - position and size of it to be displayed.
|
|
* - orientation per 90 degree.
|
|
* - add or remove surfaces to a layer.
|
|
* - order of surfaces/layers in layer/screen to be displayed.
|
|
* - commit to apply property changes.
|
|
* - notifications of property change.
|
|
*
|
|
* Management of surfaces and layers grouping these surfaces are common
|
|
* way in In-Vehicle Infotainment system, which integrate several domains
|
|
* in one system. A layer is allocated to a domain in order to control
|
|
* application surfaces grouped to the layer all together.
|
|
*
|
|
* This API and ABI follow following specifications.
