enum Cairo::Content

Overview

Content 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 content values distinct from Format values so that the implementation can detect the error if users confuse the two types.

Defined in:

cairo/content.cr
