WeChat applet API drawing fill (fill in the current path)


fill

Definition

Fill the content in the current path. The default fill color is black.

Tip: If the current path is not closed, the fill() method will connect the starting point and the end point and then fill them in. For details, see Example 1.

Tip: fill() The filled path is calculated starting from beginPath(), but fillRect( ) is included, see Example 2 for details.

Example

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