### TransformType

```typescript
{
  x: number;
  y: number;
  rotate: number;
  scale: number;
  flipX: boolean;
  flipY: boolean;
}
```

### TransformAction

```typescript
type TransformAction =
  | 'flipY'
  | 'flipX'
  | 'rotateLeft'
  | 'rotateRight'

  | 'zoomOut'
  | 'close'
  | 'prev'
  | 'next'
  | 'wheel'
  | 'doubleClick'
  | 'move'
  | 'dragRebound';
```

### ToolbarRenderInfoType
