Detailed Description

A base class to describe an arbitrary digital camera signal(Device specific interface layout only) (deprecated.

Deprecated
Beginning with the release of 3.0.0 of Impact Acquire everything specifically related to frame grabber boards will be considered as deprecated and might be removed without further notice!

This class provides access to all settings specific for digital video signals.

Note
This class will only be available if mvIMPACT.acquire.Device.interfaceLayout is set to mvIMPACT.acquire.dilDeviceSpecific before the device is opened.

Constructor & Destructor Documentation

◆ __init__()

__init__ ( self,
* args,
** kwargs )

Member Function Documentation

◆ copyDescription()

copyDescription ( self,
newName )
inherited

Creates a new camera description list as a copy of the current one.

This function can be used to create a new camera description list. It will create a deep copy of the properties referenced by this camera description and will append the new description to the list of camera descriptions.

Note
This will NOT store the new description permanently. After the driver has been closed, this data will be lost. To store the new list in a way that it will be available the next time the driver/device is opened again, mvIMPACT.acquire.CameraDescriptionBase.exportDescription must be called with the handle of the newly created description after this function.
See also
mvIMPACT.acquire.CameraDescriptionBase.exportDescription,
mvIMPACT.acquire.CameraDescriptionBase.importDescription
Returns
Parameters
newName[in] The name for the newly created camera description. This name MUST NOT match a description already existing.

◆ exportDescription()

exportDescription ( self)
inherited

Stores the current camera description on disk.

This function can be used to store the current settings of a camera description permanently so that the next time the driver is initialized these settings are restored.

When exporting a camera description a file in XML format will be written to disk.

  • On Windows® camera descriptions will be stored under PUBLIC%/Documents/Balluff/ImpactAcquire/CameraFiles (or MVIMPACT_ACQUIRE_DATA_DIR%/CameraFiles, which will point to the same folder)
  • On Unix based systems this directory will be /opt/ImpactAcquire/data/camerafiles
  • On other platforms these files will end up in the current working directory.

This behaviour can be modified by writing the property mvIMPACT.acquire.Device.customDataDirectory before initialising the device.

mvIMPACT.acquire.CameraDescriptionBase.copyDescription,
mvIMPACT.acquire.CameraDescriptionBase.importDescription
Returns

◆ getClassName()

getClassName ( self)
inherited

Returns the class this description is belonging to.

Returns
The class this description is belonging to.

◆ hObj()

hObj ( self)
inherited

Returns a unique identifier for the component collection referenced by this object.

This handle will always reference an object of type mvIMPACT.acquire.ComponentList.

Returns
A unique identifier for the component referenced by this object.

◆ importDescription()

importDescription ( self)
inherited

Updates a camera description with the data stored in a previous session or with the original default data.

When importing a camera description the device driver will try to retrieve the parameters needed from a XML file.

  • On Windows® camera descriptions MUST be stored under PUBLIC%/Documents/Balluff/ImpactAcquire/CameraFiles (or MVIMPACT_ACQUIRE_DATA_DIR%/CameraFiles, which will point to the same folder)
  • n Unix based systems this directory will be /opt/ImpactAcquire/data/camerafiles
  • On other platforms these files MUST be located in the current working directory.

This behaviour can be modified by writing the property mvIMPACT.acquire.Device.customDataDirectory before initialising the device. To get access to an XML description file within the application, these file must be copied to this directory BEFORE the device is initialized. During the initialisation process the device driver will process every file located under this location and will add them to the internal list of descriptions. Every camera located during this process and also descriptions created later on during the program operation can be selected via the property mvIMPACT.acquire.CameraSettingsFrameGrabber.type.

Note
In order not to bloat the device driver with redundant data it's wise only to store the descriptions needed for the application to run under this location.
Only camera descriptions supported by the capture device will be added to the device drivers internal list and will therefore be accessible via the mvIMPACT.acquire.CameraDescriptionManager.

To restore the default values valid during the driver was initialized the function mvIMPACT.acquire.ComponentCollection.restoreDefault can be used as well.

See also
mvIMPACT.acquire.CameraDescriptionBase.exportDescription,
mvIMPACT.acquire.CameraDescriptionBase.copyDescription
Returns

◆ restoreDefault()

restoreDefault ( self)
inherited

Restores the default for every component of this collection.

Calling this function will restore the default value for every component belonging to this collection.

Note
The caller must have the right to modify the component. Otherwise an exception will be thrown.
Returns
A const reference to the component.
