我试图使用PIL打开(Illustrator).eps文件,进行一些更改并保存.我想在打开,创建或解释对象之前将文档设置为300 dpi,将颜色模式设置为cmyk .

首先,我尝试使用PythonMagick,它的工作原理如下:

import PythonMagick
# That's NOT what I want
img72 = PythonMagick.Image()
img_file = 'epstest.eps'
img.read(img_file)
img_dens = img72.density()
print 'W: %d, H: %d' % (img.size().width(), img.size().height())
# W: 403, H: 2475 <-- See here
print 'Density Width: %r' % img_dens.width() # 72
print 'Density Height: %r' % img_dens.height() # 72

# THAT is what I want
img300 = PythonMagick.Image()
img_file = 'epstest.eps'
img300.density('300')      # set density / resolution
img300.read(img_file)      # opens with …

我正在学习Ruby on Rails并试图实现Twitter Bootstrap.我知道如何使用和编辑它,就像我之前使用它一样 - 只是没有轨道.

设置已完成,如下所示:http://ruby.railstutorial.org/chapters/filling-in-the-layout？version = 3.2#sec - custom_css - 当我读到这本书时.

发生以下错误:File to import not found or unreadable: bootstrap.scss.尝试导入时@import "bootstrap".

这是我的gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.1'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3-ruby'
gem 'bootstrap-sass', '~> 2.1.1.0'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
...

我错了什么？先感谢您! …
