可以使用以下代码获取图片的尺寸: # 获取图片尺寸width,height=image.size 1. 2. 步骤三:计算缩放比例 接下来,我们需要根据图片的尺寸和框的尺寸计算缩放比例。假设图片的尺寸为image_width和image_height,框的尺寸为box_width和box_height,则缩放比例为: # 计算缩放比例scale=min(box_width/image_width,box_heigh...

当前流行的计算机桌面应用程序大多数为图形化用户界面(Graphic User Interface,GUI)。 即通过鼠标对菜单、按钮等图形化元素触发指令,并从标签、对话框等图型化显示容器中获取人机对话信息。Python自带了tkinter 模块,实质上是一种流行的面向对象的GUI工具包 TK 的Python编程接口,提供了快速便利地创建GUI应用程序的方法。
