Hello,
Following an advice of Thomas, I tried to render Arles on my 64 bits
machine (4 Gb) of RAM. Ocitysmap fails immediately at Cairo PNG
surface creation with following backtrace:
[...]
DEBUG:ocitysmap:rendering to bbox

Error while rendering png:

MemoryError
Any idea how to allow create big PNG with Cairo?
Regards,
d.
