[英]Can someone help me with my PIL function?
def pad_image(f, width=500, height=None):
if height==None:
height = width
image = Image.new("RGB", (800, 600), (0, 0, 0, 0))
image.paste(StringIO(f), (0,0, 50, 50))
res = StringIO()
image.save(res, 'JPEG')
res.seek(0)
return res
I am trying to paste my image, f
, in a 500x500 white canvas. 我正在尝试将我的图片f
粘贴在500x500的白色画布中。 (in the middle). (在中间)。
This is my function so far, but I'm having lots of trouble. 到目前为止,这是我的职责,但是我遇到了很多麻烦。 I'm having so many problems, and I haven't even touched the height/width part. 我遇到了很多问题,甚至还没有碰过高度/宽度部分。
Traceback (most recent call last):
File "resizer.py", line 23, in <module>
thumbnail = tools.create_thumbnail(pic,300)
File "../lib/tools.py", line 84, in create_thumbnail
thumbnail_file = pad_image(thumbnail_file.read())
File "../lib/tools.py", line 92, in pad_image
image.paste(f, (0,0, 50, 50))
File "/usr/lib/python2.6/dist-packages/PIL/Image.py", line 1085, in paste
im = ImageColor.getcolor(im, self.mode)
File "/usr/lib/python2.6/dist-packages/PIL/ImageColor.py", line 101, in getcolor
color = getrgb(color)
File "/usr/lib/python2.6/dist-packages/PIL/ImageColor.py", line 97, in getrgb
raise ValueError("unknown color specifier: %r" % color)
ValueError: unknown color specifier: '\xff\xd8\xff\
the first argument to paste should be a Image
not a StringIO
so 要粘贴的第一个参数应该是Image
而不是StringIO
因此
use image.paste(Image.open(StringIO(f)), (0,0, 50, 50))
instead 使用image.paste(Image.open(StringIO(f)), (0,0, 50, 50))
代替
but you should probably check the size of f before pasting it it will only paste the upper left corner if it's bigger than 50x50 但您可能应该在粘贴前检查f的大小,如果它大于50x50,它将仅粘贴左上角
