IDS Peak comfortSDK, genericSDK, IPL, and AFL developer manuals are external documents. Please contact us if you need them.
You can save camera parameters on the camera or load them from the camera. For this, you use UserSets.
genericSDK
The available UserSets can be read via the entries of the UserSetSelector.

{
for (auto const& userSetSelectorEntry : nodemapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("UserSetSelector")->Entries())

(peak::core::nodes::NodeAccessStatus::NotImplemented == userSetSelectorEntry ->AccessStatus()))
{
// This entry is not accessible because it is not implemented and/or not available at the moment
}
else
{
// The entry is accessable
std::string stringEntry = userSetSelectorEntry->SymbolicValue();
}
}
catch (const std::exception&)

comfortSDK
The possible ParameterSets are predefined (see also UserSetSelector):
PEAK_PARAMETER_SET_DEFAULT
|
Default settings for Areascan
|
read-only
|
PEAK_PARAMETER_SET_LINESCAN
|
Default settings for line scan (not available for all cameras)
|
read-only
|
PEAK_PARAMETER_SET_LONG_EXPOSURE
|
Settings for long exposure (not available for all cameras)
|
read-only
|
PEAK_PARAMETER_SET_USER_1
|
Custom settings 1
|
read-write
|
PEAK_PARAMETER_SET_USER_2
|
Custom settings 2
|
read-write
|
Use the _GetList function to query the available ParameteSets.

Loading camera settings from camera
The standard UserSet/ParameterSet is named "Default". Additionally, you can use further UserSets/ParameterSets in which you can save or reload your own parameters. Furthermore, there are special UserSets/ParameterSets for some camera models, e.g. for long time exposure.
peak_parameter_set parameterSet = PEAK_PARAMETER_SET_DEFAULT;
peak_access_status accessStatus = peak_CameraSettings_ParameterSet_GetAccessStatus(hCam, parameterSet);
if(PEAK_IS_READABLE(accessStatus))
{
// The parameter set can be applied
peak_status status = peak_CameraSettings_ParameterSet_Apply(hCam, parameterSet);
if (PEAK_ERROR(status)) { /* Error handling ... */ }
}
else
{
// ...
}

// Load the default user set
try
{
// Set selector to "Default"
nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("UserSetSelector")->SetCurrentEntry("Default");
// Load user set
nodeMapRemoteDevice->FindNode<peak::core::nodes::CommandNode>("UserSetLoad")->Execute();
// Wait until the UserSetLoad command has been finished
nodeMapRemoteDevice->FindNode<peak::core::nodes::CommandNode>("UserSetLoad")->WaitUntilDone();

Defining camera parameters at startup
The UserSetDefault/Parameter Startup Set defines which parameter set is to be loaded when the camera starts. The saved parameters are automatically restored each time the camera is opened. This UserSet/ParameterSet is also loaded if the camera has lost power for a short time and is restarted by a reconnect. Therefore, it is recommended to adjust the UserSetDefault/Parameter Startup Set to the present application to reduce the startup time.
