ImageFile Module

The ImageFile module provides support functions for the image openand save functions.

In addition, it provides a Parser class which can be used to decodean image piece by piece (e.g. while receiving it over a network connection).This class implements the same consumer interface as the standard sgmlliband xmllib modules.

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[源代码]
• Incremental image parser. This class implements the standardfeed/close consumer interface.

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

• close()[源代码]
• (Consumer) Close the stream.

返回:An image object.引发:IOError – If the parser failed to parse the image file eitherbecause it cannot be identified or cannot bedecoded.

• feed(data)[源代码]
• (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()[源代码]
• (Consumer) Reset the parser. Note that you can only call thismethod immediately after you’ve created a parser; parserinstances cannot be reused.
