An add-color<%> object is used to additively change the RGB values of
a color% object. An add-color<%> object only exists within a
style-delta% object.
See also get-foreground-add and get-background-add.
(send an-add-color get r g b) → void? r : (box/c (integer-in -1000 1000)) g : (box/c (integer-in -1000 1000)) b : (box/c (integer-in -1000 1000))
Gets all of the additive values.
The r box is filled with the additive value for the red component of the color. The g box is filled with the additive value for the green component of the color. The b box is filled with the additive value for the blue component of the color.
(send an-add-color get-b) → (integer-in -1000 1000)
Gets the additive value for the blue component of the color.
(send an-add-color get-g) → (integer-in -1000 1000)
Gets the additive value for the green component of the color.
(send an-add-color get-r) → (integer-in -1000 1000)
Gets the additive value for the red component of the color.
(send an-add-color set r g b) → void? r : (integer-in -1000 1000) g : (integer-in -1000 1000) b : (integer-in -1000 1000)
Sets all of the additive values.
(send an-add-color set-b v) → void? v : (integer-in -1000 1000)
Sets the additive value for the blue component of the color.
(send an-add-color set-g v) → void? v : (integer-in -1000 1000)
Sets the additive value for the green component of the color.
(send an-add-color set-r v) → void? v : (integer-in -1000 1000)
Sets the additive value for the red component of the color.
