“错误:读取图像文件时数据流中断". (在OS X上为TrueType字体libjpeg和PIL) [英] "ERROR: broken data stream when reading image file" (TrueType fonts libjpeg and PIL on OS X)

问题描述

我正在运行OS X 10.6.7，Python 2.6，并编写了一个小的wxPython应用程序，该应用程序使用PIL来操纵图像并向其中添加一些文本.

I'm running OS X 10.6.7, Python 2.6, and writing a small wxPython application that uses PIL to manipulate an image and add some text to it.

尝试通过libjpeg和PIL运行PIL的大量配置问题后，我按照

After quite a bit of configuration woes with attempting to get PIL running with libjpeg and PIL, I followed the instructions at this site.

运行python setup.py build_ext -i(从Imaging-1.1.7文件夹内部)后，我得到:

Upon running python setup.py build_ext -i (from inside the Imaging-1.1.7 folder) I get:

--------------------------------------------------------------------
PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version       1.1.7
platform      darwin 2.6.1 (r261:67515, Jun 24 2010, 21:47:49)

--- TKINTER support available
--- JPEG support available
--- ZLIB (PNG/ZIP) support available
--- FREETYPE2 support available
--- LITTLECMS support available
--------------------------------------------------------------------

另外，在Imaging-1.1.7安装文件夹中运行python selftest.py，我得到:

Additionally, running python selftest.py in the Imaging-1.1.7 install folder, I get:

--------------------------------------------------------------------
PIL 1.1.7 TEST SUMMARY 
--------------------------------------------------------------------

--- ZLIB (PNG/ZIP) support ok
--- FREETYPE2 support ok
--- LITTLECMS support ok
--------------------------------------------------------------------
Running selftest:
--- 57 tests passed.

但是，当用自己的代码渲染我的第一个PIL图像时，我仍然得到:

However, when rendering my first PIL image in my own code, I still get:

File "/Library/Python/2.6/site-packages/PIL/Image.py", line 1290, in resize self.load()
File "/Library/Python/2.6/site-packages/PIL/ImageFile.py", line 215, in load raise_ioerror(e)
File "/Library/Python/2.6/site-packages/PIL/ImageFile.py", line 52, in raise_ioerror
raise IOError(message + " when reading image file")
IOError: broken data stream when reading image file

接下来的尝试让我有些茫然.有任何想法吗?导致此崩溃的代码似乎是:

I'm kind of at a loss as to what to try next. Any ideas? The code that is causing this crash seems to be:

try:
    self.img = self.img.resize((self.screenwidth, self.screenheight), 
            Image.ANTIALIAS)
    except IOError, e:
        print "Error resizing: " + str(e)
        self.img = self.img.resize((self.screenwidth, self.screenheight))
        raise 

推荐答案

您应考虑卸载PIL并按照此网站上的说明进行操作- http://jetfar.com/libjpeg-and-python -imaging-pil-on-snow-leopard/

You should consider uninstalling PIL and following the instructions on this website - http://jetfar.com/libjpeg-and-python-imaging-pil-on-snow-leopard/

尤其是您似乎想要确保libjpeg的版本为 6b ，而不是 8c (请参见下文)

In particular, it appears that you want to make sure that libjpeg is at version 6b, not 8c (see below)

我可以使用Macports在Mac OS X 10.5上重现此内容

I am able to reproduce this with Mac OS X 10.5 using macports

这与另一个问题有关: 如何解决IOError:读取图像文件时数据流中断?

This is related to a another question: How to solve IOError:broken data stream when reading image file?

那里的答案表明该错误可能与libjpeg有关

The answer there indicates that the bug might have something to do with libjpeg

据我所知，该错误似乎是由于与libjpeg v8c的向前不兼容引起的.

As far as I can tell, the error appears to be caused by a forward incompatibility with libjpeg v8c.

我无法确定到底是什么原因造成的；我所能说的是，在我使用的各种其他系统上，这些系统均未显示此行为错误(带芬克的OS X 10.5，Redhat 5.2，Ubuntu 11.10和10.10)，它们都使用libjpeg 6b.只有macports使用8c，而macports是唯一出现此错误的系统.

I cannot determine what is causing this exactly; all I can say is that on a variety of other systems I use that aren't exhibiting this behavior error (OS X 10.5 with fink, Redhat 5.2, Ubuntu 11.10 and 10.10), they all use libjpeg 6b. Only macports uses 8c, and macports is the only system where I am getting this error.
