The CairoPatternType class
(No version information available, might only be in Git)
简介
CairoPatternType is used to describe the type of a given pattern.
The type of a pattern is determined by the function used to create it.
The cairo_pattern_create_rgb() and cairo_pattern_create_rgba()
functions create CairoPatternType::SOLID patterns. The remaining
cairo_pattern_create_* functions map to pattern types in obvious ways.
