Code review comment for lp:~tomasgroth/openlp/mupdf

Looks good!
Really expecting function for us! Keep develop it!

1Q: Does it works on OS X?
2Q: I didnt get the point with PdfViewer class. Dont you use slide's system in OpenLP? Do I correctly understand that you just convert PDF to images and then show them like images? May be it will be easier to use image plugin for showing images after conversion.

And 1 more suggestion: may be it is better to use this:

os.path.isfile(os.path.join(self.get_temp_folder(), u'mainslide001.png'))

instead of this:

os.path.isfile(self.get_temp_folder() + u'/mainslide001.png')
