We already have a library for rendering SVG images using cairo. It's
called libsvg-cairo and is hosted at:
It depends on libsvg from the same place, as well as libxml2. The
libsvg code was written by ripping out all of the libart dependencies
from librsvg and replacing it with a callback interface for any

Quite likely. Cairo can draw directly to a chunk of memory that you
hand it. See:
Cairo supports only a small number of image formats, but it shouldn't
bee *too* hard to extend those if needed.

It has been built successfully on linux and mac OS X, (and several
little bugs exposed by OS X were recently fixed). In the past, a few
people have gotten it to work on Windows, but it was necessary to
manually rip out of some of the X11-related code. With the recent
ability to "configure --without-x" I would imagine that building on
Windows is now easier than before.

Cairo is implemented as two libraries: libcairo and libpixman. It also
depends on a "native" font system, (which in the current
implementation means it depends on fontconfig/freetype). But we will
probably want to substitute in support for other font systems on some
The only other minimal dependencies are quite standard: libc, libm,
Finally, the optional backends come with their own dependencies. For
example, the X Render backend depends on Xrender, X11, etc. And other
in-progress backends (OpenGL, PNG) will also have their own

You're quite welcome.
