Cairo is a native PHP extension to create and modify graphics using the Cairo
|
|
Graphics Library.

|
The Cairo Graphics Library is a 2D library written in C with support for
|
|
multiple output devices. Currently supported output targets include the X
|
|
Window System, Quartz, Win32, image buffers, PostScript, PDF, and SVG file
|
|
output. Experimental backends include OpenGL (through glitz), XCB, BeOS,
|
|
OS/2, and DirectFB. The library also has support for two types of text
|
|
manipulation and layout. The "toy" API provides demo quality support, and
|
|
the glyphs API, although full-featured, works best with a helper library
|
|
such as pango. Font backend support includes FreeType, Quartz, Win32, and
|
|
User fonts.

There are two types of computer graphics, vector and raster. Raster graphics
|
|
are the representation of images as an array of pixels. Vector graphics use
|
|
geometrical primitives such as points, lines, curves or polygons to represent
|
|
images. The primitives are created using mathematical equations. The Cairo
|
|
Graphics Library takes a vector approach to graphics, allowing smaller size,
|
|
infinite zooming, and moving, scaling and rotating without degrading image
|
|
quality.

Operations in the cairo graphics library 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, and others) This is very
|
|
similar to drawing operations for PostScript and PDF drawing.
|
|
</para>

|
|
The Cairo PHP Extension aims to provide support for all officially supported
|
|
font backends and surface backends, as well as expose all available
|
|
functionality in cairo to PHP users.
