When attempting to annotate on a viewport prior to all images being pre fetched an error is thrown and annotations are not possible on any viewport without a page refresh from that point. This is an edge case issue, but I am hoping to disable annotations until all data is pre fetched and then enable annotations at that point.
Here is the error:
isViewportPreScaled.ts:17 Uncaught TypeError: Cannot destructure property 'preScale' of 'viewport.getImageData(...)' as it is undefined. at isViewportPreScaled (isViewportPreScaled.ts:17:1) at RectangleROITool.renderAnnotation (RectangleROITool.ts:772:1) at handleDrawSvg (triggerAnnotationRender.ts:188:1) at Array.forEach (<anonymous>) at eval (triggerAnnotationRender.ts:202:1) at draw (draw.ts:10:1) at AnnotationRenderingEngine._triggerRender (triggerAnnotationRender.ts:184:1) at AnnotationRenderingEngine._renderFlaggedViewports (triggerAnnotationRender.ts:93:1)
