Colors
type
the abstract type of colors
val default : t
the default color is black
val rgb : float -> float -> float -> t
rgb r g b constructs the color that corresponds to the color code
RGB(r,g,b)
val rgb8 : int -> int -> int -> t
similar to rgb, but takes integers between 0 and 255 as argument
val cmyk : float -> float -> float -> float -> t
cmyk c m y k constructs the color that corresponds to the color code
CMYK(c,m,y,k)
val rgba : float -> float -> float -> float -> t
similar to rgb, but takes the factor of transparency
val rgb8a : int -> int -> int -> int -> t
similar to rgb8, but takes the factor of transparency
val cmyka : float -> float -> float -> float -> float -> t
similar to cmyk, but takes the factor of transparency
val is_opaque : t -> bool
test if the color is opaque
val opaque : t -> t
make a color opaque
val transparent : float -> t -> t
transparent f c multiplies by f the factor of transparency of c
val hsv : float -> float -> float -> t
hsv h s v convert an hsv color to an rgb.
0 <= h < 360, 0 <= s,v <= 1
color generator
val color_gen : float -> float -> unit -> t

X11-named Colors
val color : string -> t
color n returns the RGB color associated to name
n
(as defined in /etc/X11/rgb.txt). Raises
Not_found if
n does not
correspond to a color.
