C Specification

The XrColor4f structure is defined as:

// Provided by XR_VERSION_1_0
typedef struct XrColor4f {
    float    r;
    float    g;
    float    b;
    float    a;
} XrColor4f;


Member Descriptions
  • r is the red component of the color.

  • g is the green component of the color.

  • b is the blue component of the color.

  • a is the alpha component of the color.


Unless otherwise specified, colors are encoded as linear (not with sRGB nor other gamma compression) values with individual components being in the range of 0.0 through 1.0, and without the RGB components being premultiplied by the alpha component.

If color encoding is specified as being premultiplied by the alpha component, the RGB components are set to zero if the alpha component is zero.
