Methods

__init__(red: int = 0, green: int = 0, blue: int = 0, alpha: int = 255)[πηγή]

An object representing a color.

setHex(psHexColor: char) int[πηγή]

Set the color to values specified in case-independent hexadecimal notation. hex must start with a “#” followed by three or four hex bytes, e.g. “#ffffff” or “#ffffffff”. If only three hex bytes are supplied, the alpha will be set to 255. Calling setHex(“#ffffff”) therefore assigns values of 255 to each color component, including the alpha. Returns MS_SUCCESS or MS_FAILURE

setRGB(red: int, green: int, blue: int, alpha: int = 255) int[πηγή]

Set all four RGBA components. Returns MS_SUCCESS or MS_FAILURE

toHex() char[πηγή]

Complement to setHex, returning a hexadecimal representation of the color components. If alpha is 255 then this is three hex bytes “#rrggbb”, otherwise four hex bytes “#rrggbbaa”
