Hello,

I sent a patch to this list last year that made it possible to use
mupdf's "mudraw" instead of ghostscript's "gs" to convert pdf documents
into png files within doc-view-mode.

I've since been testing that patch and never looked back since the
switch sped up the pdf->png conversion by a factor of two and brought
anti-aliasing with it. 

In a similar fashion, I've now added support for DjVu->Tiff conversion
to doc-view-mode through djvulibre. While djvulibre's "ddjvu" has always
allowed for such conversion, I only yesterday requested[1] the necessary
feature of creating one tiff file per page, which was immediately
implemented (Mr. Bottou, if you're reading this, thanks again!).

Consequently, to have the two patches I'm attaching work as expected,
one needs the latest version of djvulibre from

  git://djvu.git.sourceforge.net/gitroot/djvu/djvulibre


Best regards,

Elias Pipping

PS: I've configured emacs with --without-imagemagick. I did not test
what happens if imagemagick is used.

PPS: If you need PDF and DjVu files to toy around with, I suggest the
ones at http://projecteuclid.org/euclid.pjm/1102986512 since they also
make a nice read.

PPPS: The first diff is against vanilla emacs 24.2.
