I'm assuming that you get the pdf from the stdout of some other program.
This isn't Python, but it works in Perl and may show you a clue for Python.

#!/usr/bin/perl
use warnings;
use strict;
use Image::Magick;

# simulate a pdf in memory, like from another program
my $rawpdf = `cat zzimage.pdf`;

my $output = Image::Magick->new();
$output->BlobToImage( $rawpdf );

$output->Write('zout.png');

#or if you want to write to stdout
#binmode STDOUT;
#$output->Write('png:-');

__END__
