RGBA
(red=1.0, green=1.0, blue=1.0, alpha=1.0)¶ A
Gdk.RGBA
is used to represent a (possibly translucent) color, in a way that is compatible with cairo’s notion of color.-
classmethod
from_color
(color)¶ Returns a new RGBA instance given a Color instance.
-
copy
()[source]¶ Returns: A newly allocated Gdk.RGBA
, with the same contents as selfReturn type: Gdk.RGBA
Makes a copy of a
Gdk.RGBA
.The result must be freed through
Gdk.RGBA.free
().New in version 3.0.
-
equal
(p2)[source]¶ Parameters: p2 ( Gdk.RGBA
) – anotherGdk.RGBA
pointerReturns: True
if the two colors compare equalReturn type: bool
Compares two RGBA colors.
New in version 3.0.
-
free
()[source]¶ Frees a
Gdk.RGBA
created withGdk.RGBA.copy
()New in version 3.0.
-
hash
()[source]¶ Returns: The hash value for self Return type: int
A hash function suitable for using for a hash table that stores
Gdk.RGBAs
.New in version 3.0.
-
parse
(spec)[source]¶ Parameters: spec ( str
) – the string specifying the colorReturns: True
if the parsing succeededReturn type: bool
Parses a textual representation of a color, filling in the red, green, blue and alpha fields of the self
Gdk.RGBA
.The string can be either one of:
- A standard name (Taken from the X11 rgb.txt file).
- A hexadecimal value in the form “\#rgb”, “\#rrggbb”, “\#rrrgggbbb” or ”\#rrrrggggbbbb”
- A RGB color in the form “rgb(r,g,b)” (In this case the color will have full opacity)
- A RGBA color in the form “rgba(r,g,b,a)”
Where “r”, “g”, “b” and “a” are respectively the red, green, blue and alpha color values. In the last two cases, “r”, “g”, and “b” are either integers in the range 0 to 255 or percentage values in the range 0% to 100%, and a is a floating point value in the range 0 to 1.
New in version 3.0.
-
to_color
()¶ Converts this RGBA into a Color instance which excludes alpha.
-
to_string
()[source]¶ Returns: A newly allocated text string Return type: str
Returns a textual specification of self in the form
rgb(r,g,b)
orrgba(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.These string forms are string forms that are supported by the CSS3 colors module, and can be parsed by
Gdk.RGBA.parse
().Note that this string representation may lose some precision, since “r”, “g” and “b” are represented as 8-bit integers. If this is a concern, you should use a different representation.
New in version 3.0.
