RGBA

A gdk.rgba.RGBA is used to represent a color, in a way that is compatible with cairo’s notion of color.

gdk.rgba.RGBA is a convenient way to pass colors around. It’s based on cairo’s way to deal with colors and mirrors its behavior. All values are in the range from 0.0 to 1.0 inclusive. So the color (0.0, 0.0, 0.0, 0.0) represents transparent black and (1.0, 1.0, 1.0, 1.0) is opaque white. Other values will be clamped to this range when drawing.

Constructors

this this(float red, float green, float blue, float alpha): Create a rgba.RGBA boxed type.
this this(void* ptr, Flag!"Take" take)

Members

Functions

cPtr void* cPtr(Flag!"Dup" dup)
copy gdk.rgba.RGBA copy(): Makes a copy of a gdk.rgba.RGBA.
equal bool equal(gdk.rgba.RGBA p2): Compares two gdk.rgba.RGBA colors.
hash uint hash(): A hash function suitable for using for a hash table that stores gdk.rgba.RGBAs.
isClear bool isClear(): Checks if an rgba value is transparent.
isOpaque bool isOpaque(): Checks if an rgba value is opaque.
parse bool parse(string spec): Parses a textual representation of a color.
self RGBA self(): Returns this, for use in with statements.
toString_ string toString_(): Returns a textual specification of rgba in the form rgb(r,g,b) or rgba(r,g,b,a), where “r”, “g”, “b” and “a” represent the red, green, blue and alpha values respectively. “r”, “g”, and “b” are represented as integers in the range 0 to 255, and “a” is represented as a floating point value in the range 0 to 1.

Properties

alpha float alpha [@property getter]: Get field alpha.
