Name
cairo.PatternRGB -- create RGB pattern
Synopsis
pat = cairo.PatternRGB(red, green, blue)
Function
Creates a new Cairo pattern corresponding to an opaque 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.

The color is specified in the same way as in ccontext:SetSourceRGB().

This function returns the newly created Cairo pattern if successful, or an error pattern in case of no memory. The caller owns the returned object and should call cpattern:Free() when finished with it.

This function will always return a valid handle, but if an error occurred the pattern status will be set to an error. To inspect the status of a pattern use cpattern:Status().

Inputs
red
