Package cairo wraps libcairo, a 2D graphics library with support for multiple output devices. Libcairo is is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available.

The cairo API provides operations similar to the drawing operators of PostScript and PDF. Operations in cairo including stroking and filling cubic Bézier splines, transforming and compositing translucent images, and antialiased text rendering. All drawing operations can be transformed by any affine transformation (scale, rotation, shear, etc.)

##Reference semantics Many types in this and related packages are references, that behave much like file handles, to underlying libcairo objects. These handles are values that can be copied at will, but the libcairo object referenced must be freed explicitly with Close (or Unmap, in the case of MappedImageSurface).

##Naming Conventions Cairo refers to this package and its related packages. Libcairo refers to the C library that this package is a binding to.

##Libcairo version This package requires libcairo version 1.12 or greater. Libcairo must be compiled with:

CAIRO_HAS_IMAGE_SURFACE

Related packages, such as cairo/ps, may require further options compiled in to libcairo, but they will be documented.

Libcairo can be found at http://cairographics.org .

##Xtensions Many types, functions, and methods are prefixed by Xtension. You may ignore these unless you are writing an extension. An extension is a package that integrates another portion of libcairo or binds with a library that supports libcairo integration.
