### Regions of Interest

 Title
 Description
IDLanROI Represents a region of interest used for analysis.
IDLanROI Properties
IDLanROI::AppendData Appends vertices to the region.
IDLanROI::Cleanup Performs all cleanup on the object.
IDLanROI::ComputeGeometry Computes the geometrical values for area, perimeter, and/or centroid of the region.
IDLanROI::ComputeMask Prepares a two-dimensional mask for the region.
IDLanROI::ContainsPoints Determines whether the given data coordinates are contained within the closed polygon region.
IDLanROI::GetProperty Retrieves the value of a property or group of properties for the object.
IDLanROI::Init Initializes the object.
IDLanROI::RemoveData Removes vertices from the region.
IDLanROI::ReplaceData Replaces vertices in the region with alternate values.
IDLanROI::Rotate Modifies the vertices for the region by applying a rotation.
IDLanROI::Scale Modifies the vertices for the region by applying a scale.
IDLanROI::SetProperty Sets the value of a property or group of properties for the object.
IDLanROI::Translate Modifies the vertices for the region by applying a translation.
IDLanROIGroup Analytical representation of a group of regions of interest.
IDLanROIGroup Properties
IDLanROIGroup::Add Adds a child to the object.
IDLanROIGroup::Cleanup Performs all cleanup on the object.
IDLanROIGroup::ComputeMask Prepares a two-dimensional mask for this group of regions.
IDLanROIGroup::ComputeMesh Triangulates a surface mesh with optional capping from the stack of regions contained within this group.
IDLanROIGroup::ContainsPoints Determines whether the given points (in data coordinates) are contained within this region group.
IDLanROIGroup::GetProperty Retrieves the value of a property or group of properties for the object.
IDLanROIGroup::Init Initializes the object.
IDLanROIGroup::Rotate Modifies the vertices for all regions within the group by applying a rotation.
