Instance Method Details

#lms_array ⇒ Array<AbcDecimal>

Returns an array representation of the color's coordinates in the LMS color space.

in the LMS color space in the order [L, M, S]

Returns:

  • (Array<AbcDecimal>) —

    An array containing the coordinates of the color

# File 'lib/abachrome/color_mixins/to_lms.rb', line 99

def lms_array
  to_lms.coordinates
end

#lms_values ⇒ Array<AbcDecimal>

Returns the LMS color space coordinates for this color.

Returns:

  • (Array<AbcDecimal>) —

    An array of LMS coordinates [L, M, S] representing the color in LMS color space

def lms_values
  to_lms.coordinates
end

#long ⇒ AbcDecimal

Returns the L component (long wavelength) from the LMS color space.

The L component represents the response of long-wavelength sensitive cone cells in the human eye, which are most sensitive to red light.

Returns:

  • (AbcDecimal) —

    The L (long wavelength) value from the LMS color space

end

#medium ⇒ AbcDecimal

Returns the M component (medium wavelength) from the LMS color space.

The M component represents the response of medium-wavelength sensitive cone cells in the human eye, which are most sensitive to green light.

Returns:

  • (AbcDecimal) —

    The M (medium wavelength) value from the LMS color space

def medium
  to_lms.coordinates[1]
end

#short ⇒ AbcDecimal

Returns the S component (short wavelength) from the LMS color space.

The S component represents the response of short-wavelength sensitive cone cells in the human eye, which are most sensitive to blue light.

Returns:

  • (AbcDecimal) —

    The S (short wavelength) value from the LMS color space

end

#to_lms ⇒ Abachrome::Color

Converts the current color to the LMS color space.

If the color is already in LMS, it returns the color unchanged. Otherwise, it uses the Converter to transform the color to LMS.

Returns:

def to_lms
  return self if color_space.name == :lms

  Converter.convert(self, :lms)
end

#to_lms! ⇒ Abachrome::Color

Converts the color to the LMS color space in place. This method transforms the current color into LMS space, modifying the original object by updating its color space and coordinates if not already in LMS.

color = Abachrome::Color.from_hex("#ff5500") color.to_lms! # Color now uses LMS color space

Returns:
