wx.canvasToTempFilePath 返回的图片大小问题和bug - WXOPEN Club

const ctx = wx.createCanvasContext('editorCanvas')

ctx.drawImage(originalImagePath, 0, 0, imageWidthPx, imageHeightPx)

ctx.draw()

wx.canvasToTempFilePath({

canvasId: 'editorCanvas',

success: function(res) {

console.log("tempFilePath",res.tempFilePath)

wx.getImageInfo({

src: res.tempFilePath,

success: function (res) {

console.log("cut imagesize:",res.width,res.height,res)

}

})

1，canvasToTempFilePath返回的图片既不是editorCanvas大小，也不是drawImage大小

2，选择图片，第一次drawImage后wx.canvasToTempFilePath没问题；第二次选择图片后，wx.canvasToTempFilePath模拟器上出bug
