Class Method Details

.convert(srgb_color) ⇒ Abachrome::Color

Converts a color from sRGB color space to XYZ color space.

This method first converts sRGB to linear RGB by removing gamma correction, then applies the linear RGB to XYZ transformation matrix. The XYZ color space is the CIE 1931 color space that forms the basis for most other color space definitions and serves as a device-independent reference.

the same alpha as the input color

Parameters:

  • The color in sRGB color space

Returns:

  • The resulting color in XYZ color space with

Raises:

  • If the input color is not in sRGB color space
