matplotlib.colors.to_rgba_array
- matplotlib.colors. to_rgba_array ( c, alpha=None ) [source]
-
Convert c to a (n, 4) array of RGBA colors.
- Parameters
-
- c Matplotlib color or array of colors
-
If c is a masked array, an ndarray is returned with a (0, 0, 0, 0) row for each masked value or row in c.
- alpha float or sequence of floats, 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)
.If alpha is a sequence and c is a single color, c will be repeated to match the length of alpha.
- Returns
-
- array
-
(n, 4) array of RGBA colors, where each channel (red, green, blue, alpha) can assume values between 0 and 1.
