2.2 Interface type
Each feature is accessible via a specific interface and has a number of attrib-
utes describing the current value / state and capabilities (e.g. value range) of a
feature. The following interfaces are defined in the GenICam standard (each
one is given with the typical widget used to map it on a graphical user inter-
face).
Interface Type Widget
IInteger maps to a slider with value, min, max, and increment
IFloat maps to a slider with value, min, and max plus a physical
unit
IString maps to an edit box showing a string
IEnumeration maps to a drop down box
ICommand maps to a command button
IBoolean maps to a check box
IRegister maps to an edit box showing a hex string
ICategory maps to an entry in a tree structuring the camera's fea-
tures
IPort maps to the camera port and is typically not shown
graphically
