C# 클래스 ClearCanvas.ImageViewer.RoiGraphics.Roi

Represents a static region of interest for the purposes of computing statistics on the contained pixels.

Roi objects are static definitions of a region of interest on a particular image. Its shape definition and the underlying pixel values are considered fixed upon construction, and hence its various properties and statistics are non-changing.

New instances of a Roi should be constructed everytime the definition of the region of interest or the underlying image pixel data has changed. The IGraphic.GetRoi method allows client code to quickly construct a new instance of a Roi based on the current definition of the graphic and the image it currently belongs to.

Contains ( PointF point ) : bool	Tests to see if the given point is contained within the region of interest. Regions of interest have no notion of coordinate system. All coordinates are inherently given relative to the image pixel space (i.e. CoordinateSystem.Source.)
Contains ( float x, float y ) : bool	Tests to see if the given point is contained within the region of interest. Regions of interest have no notion of coordinate system. All coordinates are inherently given relative to the image pixel space (i.e. CoordinateSystem.Source.)
Contains ( int x, int y ) : bool	Tests to see if the given point is contained within the region of interest. Regions of interest have no notion of coordinate system. All coordinates are inherently given relative to the image pixel space (i.e. CoordinateSystem.Source.)
CopyTo ( IPresentationImage presentationImage ) : Roi	Creates a copy of this Roi using the same region of interest shape but using a different image as the source pixel data.
GetBoundingBoxRounded ( bool constrainToImage ) : Rectangle	Returns a bounding box that has been rounded to the nearest whole pixel(s). Uses RectangleUtilities.RoundInflate to ensure the bounding box returned will encompass every pixel that is inside the ROI.
GetPixelCoordinates ( ) : IEnumerable	Gets an enumeration of the coordinates of points contained within the region of interest. Regions of interest have no notion of coordinate system. All coordinates are inherently given relative to the image pixel space (i.e. CoordinateSystem.Source.)
GetPixelValues ( ) : IEnumerable	Gets an enumeration of the modality LUT transformed pixel values contained within the region of interest rounded to the nearest integer. If the ModalityLut is null, then this method enumerates the same values as GetRawPixelValues.
