About Cairo's documentation

Cairo is not thoroughly documented in the CPAN module. To understand Cairo's commands it is necessary to refer to the C language documentation at Cairographics.org. The links on the commands illustrated on this page go to the Cairo C manual.

The Perl interface is similar to the C interface. Function arguments usually go in the same order, although sometimes, like C, the ordering is different. The function names are also similar to the C ones, without the C prefix.
