Function: getViewportContentMode()
getViewportContentMode(
viewport):ViewportContentMode|undefined
Returns the content-true mode of the viewport's bound source data when the
viewport can classify it (i.e. exposes getCurrentMode), otherwise
undefined.
Unlike the capability guards above (which test method presence), this reports
what the viewport is actually showing — the question a PLANAR_NEXT viewport
cannot answer through viewportSupportsImageSlices /
viewportSupportsVolumeId alone, since it supports both regardless of
content. See ViewportContentMode.
Parameters
• viewport: unknown
Returns
ViewportContentMode | undefined
