我试过谷歌搜索和查找其他人的问题.但是,我仍然找不到在mac os x 10.7.2 Lion上安装PIL(for python 2.6或2.7)的清晰/简单配方.

我想在图像中添加俄语文本.我在Windows机器上使用PIL 1.1.7和Python 2.7.由于PIL编译时没有libfreetype库,我在开发服务器上使用以下代码:

font_text = ImageFont.load('helvR24.pil')
draw.text((0, 0), '????? ?? ???????', font=font_text)

(helvR24.pil摘自http://effbot.org/media/downloads/pilfonts.zip)

在生产环境中,我执行以下操作:

font_text = ImageFont.truetype('HelveticaRegular.ttf', 24, encoding="utf-8")
draw.text((0, 0), '????? ?? ???????', font=font_text)

(试图使用unic,cp-1251而不是utf-8)

在这两种情况下,它都不显示俄语字符(而是显示"正方形"或虚拟字符).我认为它不适用于开发环境,因为大多数可能helvR24.pil不包含俄语字符(不知道如何检查它).但HelveticaRegular.ttf肯定有.我还检查过我的.py文件有геа-8编码.即使使用默认字体,它也不会显示俄语字符:

draw.text((0, 0), '????? ?? ???????', font=ImageFont.load_default())

我还应该尝试/验证什么？我通过/sf/answers/1311065871/查看 - 它没有帮助.

我正在使用Django的Python Web开发学习一个小Django .一切顺利,直到我尝试构建需要PIL(Python成像库)的照片应用程序.当我尝试通过管理界面添加图像时,我收到下面粘贴的错误消息.

我正在运行Windows 7,Python 2.7,Django 1.3b1和XAMPP 1.7.3并成功安装了wsgi模块(至少我是这么认为的,因为我的其余Django实验工作正常).

按照PIL站点的故障排除指南,我尝试在Python提示符下导入PIL模块:

>>>import _imaging
>>>import Image

两者都工作正常,没有显示错误.但是,尝试运行使用PIL的Django管理应用程序会导致:

任何帮助将不胜感激.

我有关于http://code.google.com/p/django-simple-captcha/项目的问题.我按照程序安装验证码,表格有效,但浏览器不加载图片.该怎么办？

我的模式:

from django.conf.urls.defaults import patterns, include, url
from django.conf import settings

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^$', 'main.views.main', name="main_page"),
    url(r'^registration$', 'main.views.registration', name="registration"),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),
    # Captcha
    url(r'^captcha/', include('captcha.urls')),
)

if settings.DEBUG:
    urlpatterns += patterns('',
        (r'^files/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}),
    )

使用ubuntu 13.10,python 2.7.5:

>>> draw = ImageDraw.Draw(im)
>>> font = ImageFont.truetype('arial.ttf', 14)
