References SetActive().
Checks whether the OSD can display the given set of sub-areas.
The return value indicates whether a call to SetAreas() with this set of areas will succeed. CanHandleAreas() may be called with an OSD that is already in use with other areas and will not interfere with the current operation of the OSD. A derived class must first call the base class CanHandleAreas() to check the basic conditions, like not overlapping etc.

Actually commits all data to the OSD hardware.
Flush() should return as soon as possible. For a true color OSD using the default implementation with in memory pixmaps, the Flush() function should basically do something like this:
LOCK_PIXMAPS; while (cPixmapMemory *pm = dynamic_cast<cPixmapMemory *>(RenderPixmaps())) { int w = pm->ViewPort().Width(); int h = pm->ViewPort().Height(); int d = w * sizeof(tColor); MyOsdDrawPixmap(Left() + pm->ViewPort().X(), Top() + pm->ViewPort().Y(), pm->Data(), w, h, h * d); DestroyPixmap(pm); }
If a plugin uses a derived cPixmap implementation, it needs to use that type instead of cPixmapMemory.

Sets this OSD to be the active one.
A derived class must call cOsd::SetActive(On).

Sets the sub-areas to the given areas.
The return value indicates whether the operation was successful. If an error is reported, nothing will have changed and the previous OSD (if any) will still be displayed as before. If the OSD has been divided into several sub-areas, all areas that are part of the rectangle that surrounds a given drawing operation will be drawn into, with the proper offsets. A new call overwrites any previous settings To set up a true color OSD, exactly one area must be requested, with its coordinates set to the full area the OSD shall cover, and the bpp value set to 32.
