canvasContext.stroke

Defined

Draws the border of the current path. The default color color is black.

Tip : stroke() a path that beginPath() but strokeRect() see example two for details.

Example

const ctx = wx.createCanvasContext('myCanvas')
ctx.moveTo(10, 10)
ctx.lineTo(100, 10)
ctx.lineTo(100, 100)
ctx.stroke()
ctx.draw()

const ctx = wx.createCanvasContext('myCanvas')
// begin path
ctx.rect(10, 10, 100, 30)
ctx.setStrokeStyle('yellow')
ctx.stroke()

// begin another path
ctx.beginPath()
ctx.rect(10, 40, 100, 30)

// only stoke this rect, not in current path
ctx.setStrokeStyle('blue')
ctx.strokeRect(10, 70, 100, 30)

ctx.rect(10, 100, 100, 30)

// it will stroke current path
ctx.setStrokeStyle('red')
ctx.stroke()
ctx.draw()
