Class: WSIViewport
A viewport which shows a microscopy view using the dicom-microscopy-viewer library. This viewport accepts standard CS3D annotations, and responds similar to how the other types of viewports do for things like zoom/pan.
This viewport required the dicom-microscopy-viewer import to be available
from the peerImport function in the CS3D init configuration. See the
example initDemo.js for one possible implementation, but the actual
implementation of this will depend on your platform.

getViewPresentation()
getViewPresentation(
viewPresSel):ViewPresentation
Gets a view presentation information specifying HOW a viewport displays something, but not what is being displayed. See getViewReference to get information on WHAT is being displayed.
This is intended to have information on how an image is presented to the user, without specifying what image s displayed. All of this information is available externally, but this method combines the parts of this that are appropriate for remember or applying to other views, without necessarily needing to know what all the attributes are. That differs from methods like getCamera which fetch exact view details that are not likely to be identical between viewports as they change sizes or apply to different images.
Note that the results of this can be used on different viewports, for example, the pan values can be applied to a volume viewport showing a CT, and a stack viewport showing an ultrasound.
The selector allows choosing which view presentation attributes to return.
Some default values are available from Viewport.CameraViewPresentation and
Viewport.TransferViewPresentation
Parameters
• viewPresSel: ViewPresentationSelector = ...
select which attributes to display.

hasImageURI()
hasImageURI(
imageURI):boolean
Checks to see if the imageURI is currently being displayed. The imageURI may contain frame numbers according to the DICOM standard format, which will be stripped to compare the base image URI, and then the values used to check if that frame is currently being displayed.
The DICOM standard allows for comma separated values as well, however, this is not supported here, with only a single range or single value being tested.
For a single value, the time range +/- 5 frames is permitted to allow the detection to actually succeed when nearby without requiring an exact time frame to be matched.
Parameters
• imageURI: string
containing frame number or range.
Returns
boolean

setDisplayAreaFit()
protectedsetDisplayAreaFit(displayArea):void
This applies a display area with a fit of the provided area to the available area. The zoom level is controlled by the imageArea parameter, which is a pair of percentage width in the horizontal and vertical dimension is scaled to fit the displayable area. Both values are taken into account, and the scaling is set so that both fractions of the image area are visible.
The panning is controlled by the imageCanvasPoint, which has two values, teh imagePoint and the canvasPoint. They are fractional values of the image and canvas respectively, with the panning set to display the image pixel at the given fraction on top of the canvas at the given percentage. The default points are 0.5.
For example, if the zoom level is [2,1], then the image is displayed such that at least twice the width is visible, and the height is visible. That will result in the image width being black, divided up on the left and right according to the imageCanvasPoint
Then, if the imagePoint is [1,0] and the canvas point is [1,0], then the right most edge of the image, at the top of the image, will be displayed at the right most edge of the canvas, at the top.

Parameters
• displayArea: DisplayArea

getDicomMicroscopyViewer()
staticgetDicomMicroscopyViewer():Promise<any>
Encapsulate the dicom microscopy fetch so that it can be replaced with the browser import function.

Returns
Promise<any>
