plastid.plotting.colors module¶
Utilities for manipulating colors and converting between representations as RGB hex strings, tuples of floats from 0.0 to 1.0, and tuples of ints from 0.0 to 255.
- plastid.plotting.colors.darken(data, amt=0.1, is255=False)[source]¶
Darken a vector of colors by fraction amt of current intensity.
- Parameters
- datamatplotlib colorspec or sequence of colorspecs
input color(s)
- amtfloat, optional
Percentage by which to darken r, g, and b. a remains unchanged (Default: 0.10)
- Returns
- numpy.ndarray
Lightened version of data
- plastid.plotting.colors.get_rgb255(inp)[source]¶
Fetch r, g, b values where r, g, b are integers ranging from 0 to 255
- Parameters
- inpRGB or RGBA sequence or str
Can be color hex string, like “#007ADF”, a matplotlib color letter like “r”, a matplotlib color name like “black, et c.” See
matplotlib.colors.colorConverter.to_rgb()
- Returns
numpy.ndarray
Numpy array of r, g, b tuples where r, g, b take integer values from 0 to 255
- plastid.plotting.colors.get_str_from_rgb(inp)[source]¶
Converts RGB tuples of floats from between 0.0 and 1.0 to RGB hex strings of type #RRGGBB
- Parameters
- inputtuple
Tuple of r, g, b values in range from 0.0 to 1.0
- Returns
- str
RGB hex string of form ‘#NNNNNN’
- Raises
- ValueError if values are out of range
- plastid.plotting.colors.get_str_from_rgb255(inp)[source]¶
Converts RGB tuples of ints from between 0 and 255 to RGB hex strings of type #RRGGBB
- Parameters
- inputtuple
Tuple of r, g, b values in range from 0 to 255
- Returns
- str
RGB hex string of form ‘#NNNNNN’
- Raises
- ValueError if values are out of range
- plastid.plotting.colors.lighten(data, amt=0.1, is255=False)[source]¶
Lighten a vector of colors by fraction amt of remaining possible intensity.
New colors are calculated as:
>>> new_colors = data + amt*(1.0 - data) >>> new_colors[:, -1] = 1 # keep all alpha at 1.0
- Parameters
- datamatplotlib colorspec or sequence of colorspecs
input color(s)
- amtfloat, optional
Percentage by which to lighten r, g, and b. a remains unchanged (Default: 0.10)
- is255bool, optional
If True, rgb values in data are assumed to be tween 0 and 255 rather than 0.0 and 1.0. In this case, return values will also be between 0 and 255.
- Returns
- numpy.ndarray
Lightened version of data
