In Python, handling images typically requires the use of third-party libraries, with Pillow being the most popular image processing library. Pillow library offers numerous functions for opening, manipulating, and saving images.<\/p>\n

Here are some basic usage examples of the Pillow library:<\/p>\n

    \n
  1. Install the Pillow library.<\/li>\n<\/ol>\n
    pip install Pillow\r\n<\/code><\/pre>\n
      \n
    1. Open and display the image.<\/li>\n<\/ol>\n
      from<\/span> PIL import<\/span> Image\r\n\r\n# \u6253\u5f00\u56fe\u50cf\u6587\u4ef6<\/span>\r\nimage = Image.open<\/span>(\"example.jpg\"<\/span>)\r\n\r\n# \u663e\u793a\u56fe\u50cf<\/span>\r\nimage.show()\r\n<\/code><\/pre>\n
        \n
      1. Resize the image:<\/li>\n<\/ol>\n
        # \u8c03\u6574\u56fe\u50cf\u5927\u5c0f<\/span>\r\nnew_size = (200<\/span>, 200<\/span>)\r\nresized_image = image.resize(new_size)\r\n\r\n# \u4fdd\u5b58\u8c03\u6574\u540e\u7684\u56fe\u50cf<\/span>\r\nresized_image.save(\"resized_image.jpg\"<\/span>)\r\n<\/code><\/pre>\n
          \n
        1. Convert image format.<\/li>\n<\/ol>\n
          # \u8f6c\u6362\u56fe\u50cf\u683c\u5f0f<\/span>\r\nimage.save(\"converted_image.png\"<\/span>)\r\n<\/code><\/pre>\n
            \n
          1. Apply a filter effect:<\/li>\n<\/ol>\n
            from<\/span> PIL import<\/span> ImageFilter\r\n\r\n# \u6dfb\u52a0\u6a21\u7cca\u6ee4\u955c<\/span>\r\nblurred_image = image.filter<\/span>(ImageFilter.BLUR)\r\n\r\n# \u4fdd\u5b58\u5904\u7406\u540e\u7684\u56fe\u50cf<\/span>\r\nblurred_image.save(\"blurred_image.jpg\"<\/span>)\r\n<\/code><\/pre>\n
            These are simply some basic usage examples of the Pillow library, you can utilize more functionalities to process and manipulate images based on your specific needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
