我一直在努力找到将文档转换为doc,docx,ppt,pptx到pdf的有效方法.到目前为止,我已经试过docsplit和oowriter,但都采取> 10秒完成任务的pptx文件有大小1.7MB.任何人都可以建议我改进方法的更好方法或建议吗？
我尝试过的:
from subprocess import Popen, PIPE
import time
def convert(src, dst):
d = {'src': src, 'dst': dst}
commands = [
'/usr/bin/docsplit pdf --output %(dst)s %(src)s' % d,
'oowriter --headless -convert-to pdf:writer_pdf_Export %(dst)s %(src)s' % d,
]
for i in range(len(commands)):
command = commands[i]
st = time.time()
process = Popen(command, stdout=PIPE, stderr=PIPE, shell=True) # I am aware of consequences of using `shell=True`
out, err = process.communicate()
errcode = process.returncode
if errcode != 0: …我正在尝试让docsplit使用我的rails应用程序.现在我只想让它在本地运行.我安装了gem和所有依赖项.所有基本示例都在命令行中工作,我能够得到
Docsplit.extract_pdf('example.doc')
在我的rails应用程序中工作.但是当我尝试使用extract_images时,即
Docsplit.extract_images('example.doc', :size => '1000x', :format => [:png, :jpg])
我收到以下错误:
Docsplit::ExtractionFailed (sh: pdfinfo: command not found):

我仔细检查并安装了所有依赖项.我猜我错过了rails中的配置.
谢谢.
有谁知道如何使用Paperclip上传多页pdf并将每个页面转换为Jpeg？
到目前为止,每次上传PDF时,它只允许我将PDF的第一页看作JPEG.但我希望能够将PDF中的每个页面上传并转换为JPEG.
是否有任何宝石或插件可以帮助我上传10-pg PDF并在数据库中转换/存储为10个JPEG文件？
我看过docsplit-images gem,但我不确定这是解决方案的最佳解决方案还是它的工作原理.
Post.rb
class Post < ActiveRecord::Base

has_attached_file :pdf,

validates_attachment_content_type :pdf,
:content_type => [ 'application/pdf' ],
:message => "only pdf files are allowed"
end
_form.html.erb
<%= form_for ([@post]), :html => { :multipart => true } do |f| %>
<%= f.file_field :pdf %>

我正在尝试使用docsplit将PDF文件拆分为图像.但似乎我的ruby安装有问题.我每次都会收到以下错误:
/usr/lib/ruby/1.8/fileutils.rb:694:in `remove_entry_secure': parent directory is world writable
这是完整的命令行输出:
$ docsplit images pdf-test.pdf
