osdViewer: implementation

[flavens]

• implementation of the osdViewer
• adaptation for regions (cf Meditationes branch)

[tobiasschweizer]

in the resources template, osdviewer is loaded correctly, but there is still an error message:

resource.component.html

        <!-- Check for incoming images -->
        <kui-still-image #OSDViewer
                       class="osd-viewer"
                       *ngIf="resource?.incomingStillImageRepresentations?.length > 0;"
                       (getImages)="changeOffsetForStillImageRepresentations($event)"
                       [images]="resource?.stillImageRepresentationsToDisplay"
                       [imageRangeStart]="0"
                       [imageRangeEnd]="4"
                       [imageChangeInterval]="5">
        </kui-still-image>

This is because osdviewer is not part of the switch case statement.

[tobiasschweizer]

there are two cases:

• resources as StillImageFileValues
• resource is pointed to by StillImageFileValues

In either case, it is sufficient to display resource?.stillImageRepresentationsToDisplay since this collection will contain all relevant images (collectImagesAndRegionsForResource).
