mult-color<%> : interface?

A mult-color<%> object is used to scale the RGB values of a color% object. A mult-color<%> object exist only within a style-delta% object.

See also get-foreground-mult and get-background-mult.

( send a-mult-color get r g b) → void?
r : ( box/c real? )
g : ( box/c real? )
b : ( box/c real? )

Gets all of the scaling values.

The r box is filled with the scaling value for the red component of the color. The g box is filled with the scaling value for the green component of the color. The b box is filled with the scaling value for the blue component of the color.

( send a-mult-color get-b ) → real?

Gets the multiplicative scaling value for the blue component of the color.

( send a-mult-color get-g ) → real?

Gets the multiplicative scaling value for the green component of the color.

( send a-mult-color get-r ) → real?

Gets the multiplicative scaling value for the red component of the color.

( send a-mult-color set r g b) → void?
r : real?
g : real?
b : real?

Sets all of the scaling values.

( send a-mult-color set-b v) → void?
v : real?

Sets the multiplicative scaling value for the blue component of the color.

( send a-mult-color set-g v) → void?
v : real?

Sets the multiplicative scaling value for the green component of the color.

( send a-mult-color set-r v) → void?
v : real?

Sets the additive value for the red component of the color.
