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#

'Declaration
 
Public Overridable Function SpacingInViewer( _
   ByVal Area As System.Drawing.Rectangle, _
   ByVal Viewer As DicomViewer _
) As System.Drawing.SizeF

public virtual System.Drawing.SizeF SpacingInViewer( 
   System.Drawing.Rectangle 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(Rectangle), 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: .NET CLR 4.8 or higher
