Clutter::Cogl::Color(3pm)
NAME
Clutter::Cogl::Color - COGL Color representation
DESCRIPTION
Colors in COGL are described as arrays of four values, one for each
channel of the RGBA representation.
The values can either be expressed as a byte value, going from 0 to
255, or as normalized floating point values, between 0 and 1.
METHODS
- (red, green, blue, alpha) = Clutter::Cogl::Color->premultiply ($color)
- o $color (array of R, G, B, A values)
- Converts a non-premultiplied color to a pre-multiplied color. For
example, semi-transparent red is (1.0, 0, 0, 0.5) when nonpremultiplied and (0.5, 0, 0, 0.5) when premultiplied.
