Details

Colord.color_get_blackbody_rgb(temp, result)

Parameters:

• temp (int) – the temperature in Kelvin
• result (Colord.ColorRGB) – the destination color

Returns:

True if temp was in range and the result accurate

Return type:

bool

Get the blackbody color for a specific temperature. If the temperature range is outside 1000K to 10000K then the result is clipped.

New in version 0.1.26.

Colord.color_get_blackbody_rgb_full(temp, result, flags)

Parameters:

• temp (float) – the temperature in Kelvin
• result (Colord.ColorRGB) – the destination color
• flags (Colord.ColorBlackbodyFlags) – some Colord.ColorBlackbodyFlags, e.g. Colord.ColorBlackbodyFlags.USE_PLANCKIAN

Returns:

True if temp was in range and the result accurate

Return type:

bool

Get the blackbody color for a specific temperature. If the temperature range is outside 1000K to 10000K then the result is clipped.

New in version 1.3.5.

Colord.color_rgb8_to_rgb(src, dest)

Parameters:

• src (Colord.ColorRGB8) – the source color
• dest (Colord.ColorRGB) – the destination color

Convert from one color format to another.

New in version 0.1.27.

Colord.color_rgb_array_interpolate(array, new_length)

Parameters:

• array ([Colord.ColorRGB]) – Input array
• new_length (int) – the target length of the return array

Returns:

An array of size new_length or None

Return type:

[Colord.ColorRGB]

Interpolate the RGB array to a different size. This uses the Akima interpolation algorithm unless the array would become non-monotonic, in which case it falls back to linear interpolation.

New in version 0.1.31.

Colord.color_rgb_array_is_monotonic(array)

Parameters:array ([Colord.ColorRGB]) – Input array Returns:True if the array is monotonic Return type:bool

Checks the array for monotonicity.

New in version 0.1.31.

Colord.color_rgb_array_new()

Returns:New array Return type:[Colord.ColorRGB]

Creates a new RGB array.

New in version 0.1.31.
