Color4f

class Color4f

RGBA color value, holding four floating point components.

Color components are always in a known order, and are unpremultiplied.

Skia’s public API always uses unpremultiplied colors.

Example:

color4f = skia.Color4f(0xFFFFFFFF)            # From int format
color4f = skia.Color4f(1.0, 0.0, 0.0, 1.0)    # From elements
color4f = skia.Color4f((1.0, 0.0, 0.0, 1.0))  # From tuple
color = color4f.toColor()                     # Convert to int format
color = int(color4f)                          # Convert to int format
r, g, b, a = tuple(color4f)                   # Convert to tuple

Methods

static Color4f.FromBytes_RGBA(rgba: int) → skia.Color4f

static Color4f.FromColor(color: int) → skia.Color4f

Returns closest Color4f to Color int.

Parameters:: color (int) – Color with Alpha, red, blue, and green components (e.g., 0xFFFFFFFF)
Returns:: Color int as Color4f

Color4f.__init__(*args, **kwargs)

Overloaded function.

__init__(self: skia.Color4f, color: int) -> None

Returns closest Color4f to ARGB Color. See FromColor().
__init__(self: skia.Color4f, red: float, green: float, blue: float, alpha: float = 1.0) -> None

Returns a new Color4f instance initialized with the given values.

red:

red components

green:

green components

blue:

blue components

alpha:

alpha components
__init__(self: skia.Color4f, t: tuple) -> None

Returns a new Color4f instance given (R, G, B) or (R, G, B, A) tuple.

Color4f.fitsInBytes(self: skia.Color4f) → bool: Returns true if all channels are in [0, 1].

Color4f.isOpaque(self: skia.Color4f) → bool

Returns true if Color4f is an opaque color.

Asserts if fA is out of range and SK_DEBUG is defined.

Returns:: true if Color4f is opaque

Color4f.makeOpaque(self: skia.Color4f) → skia.Color4f

Color4f.toBytes_RGBA(self: skia.Color4f) → int

Color4f.toColor(self: skia.Color4f) → int

Returns closest Color to Color4f.

Returns:: color as Color int

Color4f.vec(self: skia.Color4f) → memoryview: Returns a memoryview to components of Color4f, for array access.
