Test Image Select via Sapera LT or GigE Vision Compliant Applications
Sapera
Genie Sapera parameters for Image Test Patterns:
TestImageSelector = {Off = 0, Grey Horizontal Ramp = 1, Grey Vertical Ramp = 2,
Grey Diagonal Ramp Moving = 3, Purity = 4}
In CamExpert, these parameters are available in the “Sensor” tab.
See "
Accessing Features with Sapera++ LT" on page 77.
XML features for Image Test Patterns:
TestImageSelector = {Off = 0, HorizontalWedge = 1, VerticalWedge = 2,
DiagonalMovingWedge = 3}
Events
Genie supports a number of events that a control application can monitor. Events provide real time notification on
various stages of the acquisition sequence and of error conditions. A Sapera application registers callbacks for those
events that need monitoring.
Sapera Callbacks
Three types of callbacks can be registered for events when using the Genie:
• Transfer events concerning host system buffers.
• Use the Sapera Transfer Module
• In the Sapera C library: see CorXferRegisterCallback
• In the Sapera++ library: see SapXferCallbackInfo class
• Acquisition events concerning the acquisition device, specifically the Genie camera.
• Use the Sapera Acquisition Module
• In the Sapera C library: see CorAcqDeviceRegisterCallbackByName or
CorAcqDeviceRegisterCallbackByName
• In the Sapera++ library: see SapAcqDeviceCallbackInfo class
• Sapera events generated for GigE Vision devices (see SapManager::RegisterServerCallback). Note that if
Genie cameras are connected through an Ethernet switch, these GigE Vision events can only be generated after
the Auto Discovery polling function of the GigE Vision driver.
• SapManager::EventServerNew — A new device such as a Genie, has been connected while the Sapera
application is running. Resources are allocated for the device.
• SapManager::EventServerNotAccessible — The device is not accessible (device is disconnected). Sapera
resources for the device do not have to be destroyed if it is expected that the device will be reconnected.
• SapManager::EventServerAccessible — The device is accessible again (device reconnected). Sapera
resources for the device if not previously destroyed, will be used again.
