高分辨率屏幕下裁剪图片的修正办法
captcha = screenshot.crop((left, top, right, bottom))
作者的屏幕应该不是高分辨率，文本缩放是100%的。我的是1920*1080，为了看着舒服就把文本缩放调到了125%。这里把crop的各个参数都乘以相应的缩放倍数就好：
captcha = screenshot.crop((left*1.25,top*1.25,right*1.25,bottom*1.25))
def get_geetest_image(self, name='captcha.png'): """ 获取验证码图片 :return: 图片对象 """ top, bottom, left, right = self.get_position() print('验证码位置', top, bottom, left, right) screenshot = self.get_screenshot() captcha = screenshot.crop((1.25 * left,1.25 * top,1.25 * right,1.25 * bottom)) #size = 323,199 #captcha.thumbnail(size) captcha.save(name) return captcha
