[图片] 图上为开发者工具上生成的图片。 [图片] 图上为iphone6sp 生成的图片，头像变成方的了。 以下为代码，麻烦官方帮忙看下是什么问题。 canvas: function () { var that = this var context = wx.createCanvasContext('ass') var avatarurl_widths = 150; var avatarurl_heigths = 150; var avatarurl_xs = that.data.width * 0.5 - 75; var avatarurl_ys = that.data.height * 0.63; var avatarurl_width = 70; var avatarurl_heigth = 70; var avatarurl_x = that.data.width * 0.5-35; var avatarurl_y = 5; context.drawImage(that.data.downbj, 0, 0, that.data.width, that.data.height); context.setTextAlign('center') context.setFontSize(20) context.setFillStyle('#fd943f') context.fillText('用' + that.data.shopname, that.data.width * 0.5, 110) context.save(); context.beginPath(); context.arc(avatarurl_widths / 2 + avatarurl_xs, avatarurl_heigths / 2 + avatarurl_ys, avatarurl_widths / 2, 0, Math.PI * 2, false); context.clip(); context.drawImage(that.data.downimage, avatarurl_xs, avatarurl_ys, avatarurl_widths, avatarurl_heigths); context.restore(); context.arc(avatarurl_width / 2 + avatarurl_x, avatarurl_heigth / 2 + avatarurl_y, avatarurl_width / 2, 0, Math.PI * 2, false); context.clip(); context.drawImage(that.data.downpt, avatarurl_x, avatarurl_y, avatarurl_width, avatarurl_heigth); context.restore(); context.draw(); context.stroke() },
