cairo_pattern_create_rgba.RdCreates a new #cairo_pattern_t corresponding to a translucent color. The color components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped.

[cairo_pattern_t *]
Return value: the newly created #cairo_pattern_t if successful, or an error pattern in case of no memory. The caller owns the returned object and should call cairo_pattern_destroy() when finished with it.
This function will always return a valid pointer, but if an error occurred the pattern status will be set to an error. To inspect the status of a pattern use cairo_pattern_status().
