有一个商业工具pdflib availablebla，这可能会有所帮助。它有一个免费的
评估版和python绑定。
如果它只是关于文本，也许pdf2text有帮助。

If it''s only about text, maybe pdf2text helps.

首先，
http：// groups。 google.de/groups?selm=...&output=gplain
仍然适用于此。
如果你可以处理一个pdf-lib的非常基本的实现你可能会感兴趣
http://sourceforge.net/projects/pdfplayground
在CVS（或当前快照）中，您可以找到
ppg / doc / text_extract.txt用于文本提取的示例。
First of all,
http://groups.google.de/groups?selm=...&output=gplain
still applies here.
If you can deal with a very basic implementation of a pdf-lib you
might be interested in
http://sourceforge.net/projects/pdfplayground
In the CVS (or the current snapshot) you can find in
ppg/Doc/text_extract.txt an example for text extraction.
import pdffile
导入页面
import zlib
pf = pdffile.pdffile（''.. / pdf-testset1 / a.pdf''）
pp = pag es.pages（pf）
c = zlib.decompress（pf [pp.pagelist [0] [''/ Contents'']]。stream）
op = pdftool.parse_content（c）
sop = [x [1] for op in op if x [0] in ["''"，Tj]]
for a sop：
import pdffile
import pages
import zlib
pf = pdffile.pdffile(''../pdf-testset1/a.pdf'')
pp = pages.pages(pf)
c = zlib.decompress(pf[pp.pagelist[0][''/Contents'']].stream)
op = pdftool.parse_content(c)
sop = [x[1] for x in op if x[0] in ["''", "Tj"]]
for a in sop:

谢谢大家......如果我将它转换为PS，将其打印成文件或
，该怎么办？这会更容易使用吗？
Thanks guys... what if I convert it to PS via printing it to a file or
something? Would that make it easier to work with?
