Converting cairo code between languages is very easy.
C to Python
the following C code:
cairo_new_path (cr);
cairo_move_to (cr, x + radius_x, y);
to Python:
cr.new_path()
cr.move_to (x + radius_x, y)
- replace "
cairo_" with "cr." - remove "
cr" as first argument
Note that in some instances the python bindings will try to simplify, and then a direct translation is not possible. In such a case refer to the source code of pycairo, it is relatively easy to read.
Haskell
to Haskell:
newPath
moveTo (x + radius_x) y
