8 IMAGETEAM™ 4X00 Series Hardware Interface Layer SpecificationIllumOffICMediaThis function turns off the illumination LEDs.BOOL TurnLEDsOffICMedia(void)ReturnsZero on failure, non-zero on success.IllumOnICMediaThis function turns on the illumination LEDs.BOOL TurnLEDsOnICMedia(void)ReturnsZero on failure, non-zero on success.ImagerIsPoweredICMediaThis function indicates whether or not the image engine is currently in powerdown mode.BOOL ImagerIsPoweredICMedia(void)ReturnsZero if the engine is currently in powerdown mode, non-zero if it is not.ImagerPowerDownICMediaThis function puts the image engine into powerdown mode via a power enable signal.BOOL ImagerPowerDownICMedia(void)ReturnsZero if successful, non-zero otherwise.ImagerPowerOffAndSuspendICMediaThis function controls a physical switch to cycle power off the imager. This is typically implemented for Win CE suspend/resume.DWORD ImagerPowerOffAndSuspendICMedia(DWORD)Passed Arguments Description0 Normal case. Win 32 API functions are still allowed.1 Suspend/Resume. (For example, in Win CE this implies that it is not safe to call Win32or user layer functions.)
