- Constructors:
RGBA()
Methods
- class RGBA
-
- is_clear() bool
Checks if an
rgbavalue is transparent.That is, drawing with the value would not produce any change.
- is_opaque() bool
Checks if an
rgbavalue is opaque.That is, drawing with the value will not retain any results from previous contents.
- parse(spec: str) bool
Parses a textual representation of a color.
The string can be either one of:
A standard name (Taken from the CSS specification).
A hexadecimal value in the form “``rgb``”, “``rrggbb``”, “``rrrgggbbb``” or ”``rrrrggggbbbb``”
A hexadecimal value in the form “``rgba``”, “``rrggbbaa``”, or ”``rrrrggggbbbbaaaa``”
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)”
A HSL color in the form “hsl(hue, saturation, lightness)”
A HSLA color in the form “hsla(hue, saturation, lightness, alpha)”
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.
- Parameters:
spec – the string specifying the color
- to_string() str
Returns a textual specification of
rgbain the formrgb(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
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.
