thumbnail()在Pillow(PIL)模块中使用该方法时,必须遵循以下约定,其中使用两组(嵌套)括号:
pil_image.thumbnail((128,128))
如果只使用一个集合,Python会生成以下错误:
TypeError: 'int' object is not subscriptable
最里面的括号是否有正式名称？
PS:以下也有效:
box = 128, 128 # No parentheses needed.
pil_image.thumbnail(box)
另外:Python解析器的一部分缺点是无法在这里弄清楚意图吗？
如果我使用该命令sudo pip install Pillow,它运行正常,直到清理阶段:(这是来自日志文件的完整错误消息)
clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

我正在尝试使用枕头来裁剪图像，但是它似乎不起作用。我有以下代码：
im = Image.open('the_image.jpg')
print 'ORIGINAL SIZE: ', im.size
im.crop((1087, 0, 1820, 2197))
print 'CROPPED SIZE: ', im.size
在终端上打印此：
ORIGINAL SIZE: (2908, 2197)
CROPPED SIZE: (2908, 2197)
有人知道为什么种植似乎无效吗？欢迎所有提示！
