@sedghi As I left into the code comment, we would need a new icon to enable the toggle button for image overlays on the toolbar. |

Great work.
See my minor comments. The major comment is to clean up all the cachedStats, canvases, svg nodes etc. that you create on destroy. Maybe this is something we need to add at cs3d level that when a toolGroup is destroyed each tool should run their own destroy as we see here it is storing a lot of state that will later cause memory leak IMO

please follow the new eslint rule -> no same line if statement

we should cache this, as we hit this A LOT! so this.overlayCache.get(imageId) if not found grab from metadata and add it to the cache

| overlayMetadata: any[], | ||
| color: number[] = [127, 127, 127, 255] |

there is no need for default color here, as the configuration has a default

I prefer less indentation. So can we early return on the opposite condition and make indentation one less?

I think this is already implemented in either BaseAnnotationTool or AnnotationTool
- added new icon for toggle DICOM overlay - use new exported classes and functions from CS3D - allow ToolbarService to initialize toggles - setToolActive command now handles toggles - reference lines tool and DICOM overlay tool use the setToolActive command
…nder image overlay (pixel overlay) of the DICOM images (OHIF#3163) Co-authored-by: Joe Boccanfuso <[email protected]>
Context
DICOM images can have Overlay Plane and this overlay can be one of two types: "G" for graphics, and "R" for "ROI".
We want to be able to render "G" type overlays: image overlays or pixel overlays, over the DICOM image.
