Detailed Description

Region of Interest (ROI) feature implementation for auto controllers.

The Roi class provides a feature interface for managing the region of interest parameter of auto controllers. This feature defines the rectangular area within the image that the automatic algorithms should analyze for exposure, focus, white balance, and other automatic adjustments.

By setting an ROI, users can focus the automatic algorithms on specific parts of the image, such as:

• A subject in portrait photography
• A specific area in industrial inspection
• The center region to avoid edge effects
• Any custom rectangular region of importance

This class inherits from IFeature<peak::common::Rectangle> and provides serialization support for configuration persistence.

Note

The ROI coordinates must be within the image boundaries and cannot have negative x or y values.

Constructor & Destructor Documentation

Roi()

Roi ( std::shared_ptr< peak::afl::Controller > controller )

inlineexplicit

Constructs a Roi feature with the specified controller.

Parameters

[in]

controller

Shared pointer to the auto controller that will be used to manage the ROI parameter. The controller must support ROI operations.

Precondition

controller must not be null

controller must support ROI functionality

Since

1.8

Member Function Documentation

Deserialize()

void Deserialize ( const peak::common::serialization::IArchive & archive )

inlineoverridevirtual

Deserializes the ROI from an archive.

Loads the region of interest rectangle from the provided archive and applies it to the controller. The ROI is expected to be stored as a sub-archive with the key "Roi" containing X, Y, Width, and Height values.

Parameters

[in]

archive

The archive to read the ROI from

Exceptions

May	throw serialization exceptions if the archive operation fails
May	throw controller exceptions if the deserialized ROI is invalid

See also

Serialize()

Since

1.8

Implements ISerializable.

Get()

peak::common::Rectangle Get ( ) const

inlineoverridevirtual

Gets the current region of interest rectangle.

Retrieves the currently configured rectangular area that the automatic algorithms are analyzing within the image.

Returns

The current ROI as a Rectangle object

Exceptions

May	throw exceptions based on the underlying controller implementation if the controller is in an invalid state.

Set()

peak::common::Rectangle

Since

1.8

Implements IFeature< peak::common::Rectangle >.

Serialize()

void Serialize ( peak::common::serialization::IArchive & archive ) const

inlineoverridevirtual

Serializes the current ROI to an archive.

Stores the current region of interest rectangle in the provided archive for configuration persistence. The ROI is stored as a sub-archive with the key "Roi" containing X, Y, Width, and Height values.

Parameters

[in,out]

archive

The archive to write the ROI to

Exceptions

May	throw serialization exceptions if the archive operation fails

Deserialize()

Since

1.8

Implements ISerializable.

Set()

void Set ( const peak::common::Rectangle & value )

inlineoverridevirtual

Sets the region of interest rectangle.

Sets the rectangular area within the image that the automatic algorithms should analyze. The ROI defines the focus area for automatic exposure, focus, white balance, and other adjustments.

Parameters

[in]

value

The rectangle defining the ROI. Must have non-negative x and y coordinates and must fit within the image boundaries.

Exceptions

peak::afl::error::InvalidParameterException	if x or y coordinates are negative
May	throw additional exceptions based on the underlying controller implementation if the ROI is outside image boundaries or invalid.
