well, with a quick googling, I can't seem to find any docs for the poppler python bindings. So, if you can figure out how to get poppler to render to an image buffer, we can probably tell you how to show that with wx, and least if you know a bit about what the poppler image buffer is like.

I'm not sure if what you want to do is show a PDF within wxPython, but
if so, maybe this example from last year might help:

There's an image you can see in that message, as well as the code that
produced it.

Careful about keeping the threads straight -- this could get lost.

Thanks for so fast response. I found a method in poppler:

page.render_to_pixbuf (x, y, sixex, SizeY, pixbuf)

The only problem is that pixbuf must be an object. gtk.gdk.pixbuf
Could you help me with this information??

That *may* be possible to get from wxGTK, but not from the other platforms. So it looks like you may need to go with the code Che pointed too -- which creates a Cairo context to pass to poppler.

I'm a little surprised poppler doesn't have a way to create a pixel buffer itself, but I guess it's designed to be tied to GTK. Too bad -- it sure could be useful in a GUI-free environment (web server, etc)

Not sure that helped much,

It's not poppler, but swftools has a module named 'gfx' that can
render a pdf page to a buffer you can read into a wx.Bitmap

http://wiki.swftools.org/index.php/Python_gfx_module

I think it's based on xpdf
