Lasem is a C/Gobject based SVG/Mathml renderer. It uses cairo and pango as it's rendering abstraction layer, and then support numerous output formats: xlib, PNG, SVG, PDF, PS, EPS...
The API tries to follow the SVG and MathML DOM.
It currently includes two simple applications:
lasem-render, which takes a filename as argument and generates either a SVG, a PDF or a PS file, depending on the output file extension. There's a debug mode option (-d) that displays the bounding boxes of elements as blue rectangles, the logical extents of text as red boxes and the ink extents of text as green boxes. It accepts either MathML, Latex maths and SVG input. For the latex input, lasemrender uses the embedded itex2mml library for the conversion to MathML.
lsm-test, which, if launched without argument, renders recursively all svg and mml files in a directory, and generate an html file which displays the browser rendering, lasem rendering, and if present the reference output. The html filename is lasemtest.xml. It's main use is the rendering of the sample files in the samples directory, by invoking "cd test && ./lsm-test data".
The latest documentation is available here.
The Lasem test suite is rendered in a single page here. The first column is the Lasem rendering, the middle one the reference rendering and the last one the rendering of your browser.
Lasem uses the meson build system ( http://mesonbuild.com/ ). After you have downloaded the latest release from https://github.com/LasemProject/lasem/releases, you can build and install Lasem like any other meson project:
meson build
cd build
ninja
ninja install
The build can be configured at any time using meson configure in the build
directory. meson configure invoked without any other argument will show the
configuration options.
On some platforms (like Ubuntu), you may have to configure the dynamic linker (ld) to let it know where the aravis libraries are installed, and run ldconfig as root in order to update ld cache.

For the runtime, the following ttf fonts should be installed: cmr10, cmmi10, cmex10 and cmsy10. They are provided by the lyx-fonts package in fedora, and the fonts-lyx package in debian/ubuntu.
