WeChat small program API drawing setMiterLimit (set maximum tilt)

Drawing interfaces and methods

canvasContext.setMiterLimit

Defined

Set the maximum miter length, which refers to the distance between the inner and outer corners at the intersection of the two lines. I t setLineJoin() is miter. Beyond the maximum tilt length, the connection will be displayed as lineJoin bevel

Parameters

Example

const ctx = wx.createCanvasContext('myCanvas')
ctx.beginPath()
ctx.setLineWidth(10)
ctx.setLineJoin('miter')
ctx.setMiterLimit(1)
ctx.moveTo(10, 10)
ctx.lineTo(100, 50)
ctx.lineTo(10, 90)
ctx.stroke()

ctx.beginPath()
ctx.setLineWidth(10)
ctx.setLineJoin('miter')
ctx.setMiterLimit(2)
ctx.moveTo(50, 10)
ctx.lineTo(140, 50)
ctx.lineTo(50, 90)
ctx.stroke()

ctx.beginPath()
ctx.setLineWidth(10)
ctx.setLineJoin('miter')
ctx.setMiterLimit(3)
ctx.moveTo(90, 10)
ctx.lineTo(180, 50)
ctx.lineTo(90, 90)
ctx.stroke()

ctx.beginPath()
ctx.setLineWidth(10)
ctx.setLineJoin('miter')
ctx.setMiterLimit(4)
ctx.moveTo(130, 10)
ctx.lineTo(220, 50)
ctx.lineTo(130, 90)
ctx.stroke()

ctx.draw()
