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. * https://at.projects.genivi.org/wiki/display/PROJ/Wayland+IVI+Extension+Design */ #ifndef _IVI_LAYOUT_EXPORT_H_ #define _IVI_LAYOUT_EXPORT_H_ #ifdef __cplusplus extern "C" { #endif /* __cplusplus */ #include #include #include "stdbool.h" #include #include #define IVI_SUCCEEDED (0) #define IVI_FAILED (-1) #define IVI_INVALID_ID UINT_MAX struct ivi_layout_layer;
