# The CairoImageSurface class

(PECL cairo >= 0.1.0)

## Introduction

CairoImageSurface provide the ability to render to memory buffers either allocated by cairo or by the calling code. The supported image formats are those defined in CairoFormat.

## Class synopsis

CairoImageSurface extends CairoSurface {
