Package Exports

@icanvas/renderer/2d

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@icanvas/renderer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

canvas2D渲染器

使用基本canvas2d方法进行渲染

主渲染器

import Renderer from '@icanvas/renderer/2d';
var Render = new Renderer(width,height);

属性

Render.Context 主Canvas上下文

方法

Render.Run(Stage,Interval=1000/60,Callback) 循环渲染

Render.Update(Stage,Context,Clear) 单步渲染

扩展CanvasRenderingContext2D类

    var Context = canvas.getContext('2d');

Context.SetSize(width,height) 设置canvas大小

Context.Clear(x,y,width,height) 清空canvas^{默认全部清空}

Context.FontSet(font,fillStyle,textAlign,textBaseline) 设置上下文

Context.Stroke(strokeStyle,lineWidth) 设置上下文并描边

Context.Fill(fillStyle) 设置上下文并填充

Context.Image(key,x,y,width,height) 快速居中绘制图片^{需要图片加载器配合}

Context.Polygon(...args) 快速绘制多边形

Context.ArcRect(x,y,width,height,radius) 快速绘制圆角矩形

Context.PolygonTidy(x,y,radius,sides,rotate,radius) 快速绘制正多边形

Context.DashLine(x1,y1,x2,y2,dashLength=12,emptyLength=3) 快速绘制虚线

WebGL渲染器

WebGL渲染器还在开发中。。。
