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).

Usage examples

• Basic - This project show how to use the component in a scenario when is not required a full control on the internal state. This is the easist React SVG Pan Zoom usage.
• Controlled state - This advanced project show a scenario in which the parent component has a full control of the svg viewer. The state is owned by the parent and injected on the viewer throught props. Any state change request is performed by two callbacks onChangeValue(value) and onChangeTool(tool). This demo apply the same pattern of an <input> tag (React Controlled Components).
• Redux - This advanced project show a scenario in which a redux store handle the state. Each component can dispatch a Redux action and edit the current view of the viewer.
