matplotlib.colors.to_rgba#

matplotlib.colors.to_rgba(c, alpha=None)[source]#

Convert c to an RGBA color.

Parameters:
cMatplotlib color or np.ma.masked
alphafloat, optional

If alpha is given, force the alpha value of the returned RGBA tuple to alpha.

If None, the alpha value from c is used. If c does not have an alpha channel, then alpha defaults to 1.

alpha is ignored for the color value "none" (case-insensitive), which always maps to (0, 0, 0, 0).

Returns:
tuple

Tuple of floats (r, g, b, a), where each channel (red, green, blue, alpha) can assume values between 0 and 1.
