1Cairo is a vector graphics library with cross-device output 2support. Currently supported output targets include the X Window 3System and in-memory image buffers. PostScript and PDF file output is 4planned. Cairo is designed to produce identical output on all output 5media while taking advantage of display hardware acceleration when 6available (eg. through the X Render Extension). 7 8Cairo provides a stateful user-level API with capabilities similar to 9the PDF 1.4 imaging model. Cairo provides operations including stroking 10and filling Bezier cubic splines, transforming and compositing translucent 11images, and antialiased text rendering. 12
