使用python3显示PDF文件 [英] Displaying PDF files with python3

问题描述

我想编写一个显示PDF文件的python3/PyGTK3应用程序，但是我找不到一个允许我执行此操作的python软件包.
有 pypoppler ，但它看起来已经过时(?)，而且似乎不支持python3(?)

您有什么建议吗?

请注意，我不需要花哨的功能，例如pdf表单，操作或书写.

解决方案

事实证明，新版本的poppler-glib不需要这样的绑定.它们与GObject Introspection文件一起提供，因此可以按以下方式导入和使用:

#!/usr/bin/python3

from gi.repository import Poppler

document = Poppler.Document.new_from_file("file:///home/me/some.pdf", None)
print(document.get_pdf_version_string())

那很容易，不是吗?我花了几个小时才发现...

请注意，如果还要导入GTK，则至少需要poppler-0.18.

这是带有GUI的另一个最小示例:

#!/usr/bin/python3

from gi.repository import Poppler, Gtk

def draw(widget, surface):
    page.render(surface)

document = Poppler.Document.new_from_file("file:///home/me/some.pdf", None)
page = document.get_page(0)

window = Gtk.Window(title="Hello World")
window.connect("delete-event", Gtk.main_quit)
window.connect("draw", draw)
window.set_app_paintable(True)

window.show_all()
Gtk.main()

I want to write a python3/PyGTK3 application that displays PDF files and I was not able to find a python package that allows me to do that.
There is pypoppler, but it looks outdated (?) and does not seem to support python3 (?)

Do you have any suggestions?

EDIT: Note, that I don't need fancy features, like pdf forms, manipulation or writing.

解决方案

It turns out, that newer versions of poppler-glib don't require bindings as such. They ship with GObject Introspection files and can therefore be imported and used as follows:

#!/usr/bin/python3

from gi.repository import Poppler

document = Poppler.Document.new_from_file("file:///home/me/some.pdf", None)
print(document.get_pdf_version_string())

That was easy, wasn't it? It took me hours to find that out ...

Note that one needs at least poppler-0.18, if one wants to import GTK as well.

Here is another minimal example with a GUI:

#!/usr/bin/python3

from gi.repository import Poppler, Gtk

def draw(widget, surface):
    page.render(surface)

document = Poppler.Document.new_from_file("file:///home/me/some.pdf", None)
page = document.get_page(0)

window = Gtk.Window(title="Hello World")
window.connect("delete-event", Gtk.main_quit)
window.connect("draw", draw)
window.set_app_paintable(True)

window.show_all()
Gtk.main()
