SpacingInViewer Method

In This Topic

This method returns the Pixel Spacing within the region specified by Area, in a particular viewer

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Overridable Function SpacingInViewer( _
   ByVal Area As SkiaSharp.SKRectI, _
   ByVal Viewer As DicomViewer _
) As SkiaSharp.SKSize

'Usage
 
Dim instance As DicomImage
Dim Area As SkiaSharp.SKRectI
Dim Viewer As DicomViewer
Dim value As SkiaSharp.SKSize
 
value = instance.SpacingInViewer(Area, Viewer)

public virtual SkiaSharp.SKSize SpacingInViewer( 
   SkiaSharp.SKRectI Area,
   DicomViewer Viewer
)

public:
virtual SkiaSharp.SKSize SpacingInViewer( 
   SkiaSharp.SKRectI Area,
   DicomViewer^ Viewer
)

Parameters

Area: The Area for which the spacing should be calculated
Viewer: The viewer for which the spacing applies

Return Value

The pixel spacing of the requested area

Remarks

This method returns the Pixel Spacing within a Region of the DicomImage. Note, one Image may have multiple regions with different pixel spacing values, so this method may return different values for different inputs.

Note that for non-3D images, this returns exactly the same value as Spacing(SKRectI), but that 3D images have scaling dependent on the viewer size, as autoscaling is used for such images.

Example

DicomImage image = new DicomImage("yuour_dicom_image.dcm");
var imageWidth = image.Size.Width;
var imageHeight = image.Size.Height;
var spaceViewer = image.SpacingInViewer(new Rectangle(0, 0, imageWidth, imageHeight), Viewer); // Example value {Width = 0.714 Height = 0.714} mm

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
