new(r : UInt8, g : UInt8, b : UInt8, a : UInt8)

Initialize the color with four 8-bit unsigned integers representing red, green, blue, and alpha.

new(packed : UInt32)

Initialize the color with a 32-bit unsigned integer representing red, green, blue, and alpha.

opaque

Initialize the color with full alpha.

raw

Pack the integers into a 32-bit unsigned integer.

to_rgba64

Convert the RGBA32 to an RGBA64 by upscaling each integer to 16 bits.

transparent

Initialize the color with zero alpha.

with_alpha(alpha : UInt8)

Initialize the color with the same red, green, and blue values, but with the specified alpha value.
