The CairoContent class

(Não há informação de versão disponível, talvez apenas no SVN)

Introdução

CairoContent is used to describe the content that a surface will contain, whether color information, alpha information (translucence vs. opacity), or both.

Note: The large values here are designed to keep CairoContent values distinct from CairoContent values so that the implementation can detect the error if users confuse the two types.
