## Features
This component can work in four different modes depending on the selected tool:
- With the tool **pan** the user can move the image and drag it around within the viewer, but can't interact with SVG child elements.
- With the tool **zoom** the user can scale the image either with a point click or selecting a region to zoom the specified area, but can't interact with SVG child elements.
- With the tool **none** the user can interact with SVG child elements and trigger events.
- With the tool **auto** the user can interact with SVG child elements, perform *pan* (dragging the image), *zoom in* (double click), *zoom out* (double click + shift).
