PyTomUtil

A collection of helpful utilties in Python.

Similar to the tecoradors-elunico package I have but that is just for useful decorators. This is any useful utility: function or class or other

frange class works like range but allows floating point values. Requires start, stop, and step to always be specified

class frange:
    def __init__(self, start: float, stop: float, step: float) -> None:
        ...

    def __iter__(self):
        ...

    def __next__(self):
        ...

lerp is a function for linearly interpolating between two values according to a percentage between 0.0 and 1.0.

Linear Interpolation in Wikipedia

def lerp(a: float, b: float, t: float) -> float:
    return (1 - t) * a + t * b

SRGBColor is a class for managing colors in SRGB color space. Works with linear interpolation between colors and luminance values. The class accepts r, g, b and optionally an alpha channel in the range 0.0 to 1.0.

class SRGBColor:
    def __init__(self, r: float, g: float, b: float, a: float = 1.0):
        ...

    def lerp(self, other: "SRGBColor", percent: float) -> "SRGBColor":
        ...

    @property
    def luminance(self) -> float:
        """Given an sRGB color as 3 RGB values between 0 and 1, return their relative luminance"""
        ...
