貌似 setTransfrom 真机的表现和模拟器中的表现不一致。textarea输入严重问题。
onLoad() {
this.context = wx.createCanvasContext("surface");
for ( var i = 0; i < 4; ++i ) {
this.context.save();
this.context.setTransform(1, 0, 0, 1, 100 * i, 100 * i);
this.context.fillStyle = "rgba(0, 200, 0, 0.5)";
this.context.fillRect(0, 0, 100, 100);
this.context.fill();
this.context.restore();
}
this.context.draw();
}
