在 toolbarProps 中添加三个回调，可以响应 保存、删除、和 边框设定 三个按钮被点击的事件。

toolbarProps:{ onSave, onDelete, onBorderSet, onUndo, onRedo }

详见 shape-reviewer-v1 项目中 mainView.js中的使用细节。

以下是原 README

react-svg-pan-zoom is a React component that adds pan and zoom features to the SVG images. It helps to display big SVG images in a small space.

Live Demo

available at http://chrvadala.github.io/react-svg-pan-zoom/

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).
