### 概要
HBuilderX2.2.5（alpha）开始nvue页面支持Canvas。

Canvas插件基于[GCanvas](https://github.com/alibaba/GCanvas)实现了微信小程序[CanvasContext API](https://developers.weixin.qq.com/miniprogram/dev/api/canvas/CanvasContext.html),  W3C [WebGL API](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API),
此工程为uni-app项目中nvue页面使用Canvas的演示demo

### 使用
1. 将gcanvas目录复制到HBX uniapp 工程下
2. 在页面中引入canvas js
```javascript
import {
	enable,
	WeexBridge
} from '[自己的路径]/gcanvas/index.js';
```
3. 获取Canvas context
```javascript
 /*通过元素引用获取canvas对象*/
 var ganvas = this.$refs["gcanvess"];
 var canvasObj = enable(ganvas, {bridge: WeexBridge});
 /*获取绘图所需的上下文*/
 var context = canvasObj.getContext('2d');
 var gl = canvasObj.getContext("webgl");
 /*调用具体API*/
```
## API支持情况
* Canvas API

### 云端打包
Canvas是作为独立的模块，打包时需要选择使用Canvas模块才能正常使用相关的功能。
需要在manifest.json的代码视图中配置如下（暂时还不支持可视化界面操作）：
```javascript
    "app-plus" : {
        /* 模块配置 */
        "modules" : {
            "Canvas" : "nvue canvas"    //使用Canvas模块
        },
	//...
    },
    //...
```
保存好提交云端打包。

### 离线打包
#### Android
复制weex_gcanvas-release.aar到libs目录下，然后在build.gradle中添加依赖即可。（weex_gcanvas-release.aar位于SDK/libs目录下）

#### iOS
导入 对应版本离线SDK目录下 SDK/Libs/libDCUniCanvas.a 库。
