Poppler is a library for rendering PDF files used by GTK+ and Qt applications. There is a widget for PyQt4 and PyGTK. To compile those widgets you need poppler-bindings package with Qt4 and/or GTK support. Snapshot of pypoppler-qt4 is available on pyqt4-extrawidgets. To compile the widget execute python configure.py, make, make install.
In the package you will find test-poppler.py, which will open a PDF file given as the argument for the file. You can use up/down arrows to change pages.
import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import QtPoppler
from pictureflow import *
app = QApplication(sys.argv)
w = PictureFlow()
d = QtPoppler.Poppler.Document.load('file.pdf')
d.setRenderHint(QtPoppler.Poppler.Document.Antialiasing and QtPoppler.Poppler.Document.TextAntialiasing)
page = 0
pages = d.numPages() - 1
while page < pages:
page += 1
print page
w.addSlide(d.page(page).renderToImage())
w.show()
sys.exit(app.exec_())
