Detailed Description

A collection of region of interests (ROIs).

Note
This class is considered experimental and subject to substational change. We mean it.

ROIs, essentially defined by the minimum and maximum index coordinates of an axis-aligned box, are represented by the nested ROI::Element class. These index coordinates are relative to a common TimeGeometry.

All ROIs are required to have a unique ID by which they can be accessed.

ROIs can optionally have properties (PropertyList), also called default properties. In case of time-resolved ROIs, each time step can optionally have properties, too. These properties have precedence over the default properties. In other words, the default properties may contain fallback properties which are queried when a property is not defined at a certain time step. This allows for an opt-in dynamic appearance of ROIs over time, for example by changing color or opacity.

ROIs are rendered both in 3-d and 2-d views as cubes, resp. cutting slices of these cubes. They support the following ROI::Element properties:

ROIs display a customizable caption at their bottom-left corner. It is defined by the base data property caption (StringProperty). By default it is set to "{name} ({ID})". Braces are used to define placeholders which are replaced by their corresponding ROI::Element properties. {ID} is a special placeholder which will be replaced by the ID of the ROI::Element instead. The caption is allowed to include line breaks. Rendering of captions can be customized through the following data node properties:

◆ RequestedRegionIsOutsideOfTheBufferedRegion()

bool mitk::ROI::RequestedRegionIsOutsideOfTheBufferedRegion ( )
overridevirtual

Determine whether the RequestedRegion is outside of the BufferedRegion.

This method returns true if the RequestedRegion is outside the BufferedRegion (true if at least one pixel is outside). This is used by the pipeline mechanism to determine whether a filter needs to re-execute in order to satisfy the current request. If the current RequestedRegion is already inside the BufferedRegion from the previous execution (and the current filter is up to date), then a given filter does not need to re-execute

Implements mitk::BaseData.

◆ SetRequestedRegion()

void mitk::ROI::SetRequestedRegion ( const itk::DataObject *  data)
overridevirtual

Set the requested region from this data object to match the requested region of the data object passed in as a parameter.

This method is implemented in the concrete subclasses of BaseData.

Implements mitk::BaseData.

◆ SetRequestedRegionToLargestPossibleRegion()

void mitk::ROI::SetRequestedRegionToLargestPossibleRegion ( )
overridevirtual

Set the RequestedRegion to the LargestPossibleRegion.

This forces a filter to produce all of the output in one execution (i.e. not streaming) on the next call to Update().

Implements mitk::BaseData.

◆ VerifyRequestedRegion()

bool mitk::ROI::VerifyRequestedRegion ( )
overridevirtual

Verify that the RequestedRegion is within the LargestPossibleRegion.

If the RequestedRegion is not within the LargestPossibleRegion, then the filter cannot possibly satisfy the request. This method returns true if the request can be satisfied (even if it will be necessary to process the entire LargestPossibleRegion) and returns false otherwise. This method is used by PropagateRequestedRegion(). PropagateRequestedRegion() throws a InvalidRequestedRegionError exception if the requested region is not within the LargestPossibleRegion.

Implements mitk::BaseData.
