在上述示例中,首先使用os.getcwd()获取当前工作目录,然后使用os.path.join()构建文件路径,将当前工作目录、文件夹名称和文件名拼接在一起。最后,使用os.path.exists()检查文件是否存在,如果存在,则使用Image.open()方法从文件中创建图像对象,进行后续的图像处理操作。
Image模块是在PythonPIL图像处理中常见的模块,对图像进行基础操作的功能基本都包含于此模块内。如open、save、conver、show…等功能。 (1)open类 Image.open(file) ⇒ image Image.open(file, mode) ⇒ image 要从文件加载图像,使用 open() 函数, 在 Image 模块: ...
