ImageFile Module

Example: Parse an image¶

from PIL import ImageFile

fp = open("lena.pgm", "rb")

p = ImageFile.Parser()

while 1:
    s = fp.read(1024)
    if not s:
        break
    p.feed(s)

im = p.close()

im.save("copy.jpg")

Parser¶

class PIL.ImageFile.Parser[source]¶

Incremental image parser. This class implements the standard feed/close consumer interface.

In Python 2.x, this is an old-style class.

close()[source]¶

(Consumer) Close the stream.

返回:	An image object.
引发 IOError:	If the parser failed to parse the image file either because it cannot be identified or cannot be decoded.

feed(data)[source]¶

(Consumer) Feed data to the parser.

参数:	data – A string buffer.
引发 IOError:	If the parser failed to parse the image file.

reset()[source]¶

(Consumer) Reset the parser. Note that you can only call this method immediately after you’ve created a parser; parser instances cannot be reused.
