Class EXTGLColorspaceSCRGBLinear
This extension provides an extended sRGB (also called scRGB) color space option for applications to choose from when creating an EGLSurface
.
This extension defines the linear display referred scRGB color space. It has the same white point and color primaries as sRGB, and thus is
backward-compatible with sRGB. Refer to the IEC 61966-2-2:2003 standard for details on scRGB color space.
This extension chooses to use floating-point formats for scRGB color space. For each color channel, the floating-point values of 0.0 and 1.0 still correspond to sRGB chromaticities and luminance levels. However, scRGB space allows for color values beyond the range of [0.0, 1.0], and can thus achieve a larger color volume than that of sRGB. As it is display referred, scRGB space makes assumptions of how the floating-point color values should map to luminance levels by the underlying display pipeline. The expected mapping is such that a color value of (1.0, 1.0, 1.0) corresponds to a luminance level of 80 nits on a standardized studio monitor. As the color value per channel goes beyond 1.0 and up to 125.0, the corresponding luminance levels also increase linearly to a maximum of 10000 nits.
