EXTSRGB (LWJGL 3.0.0 SNAPSHOT)

java.lang.Object
- org.lwjgl.opengles.EXTSRGB

```
public final class EXTSRGB
extends java.lang.Object
```
Native bindings to the EXT_sRGB extension.
The sRGB color space is based on typical (non-linear) response of the human eye. It has been standardized by the International Electrotechnical Commission (IEC) as IEC 61966-2-1. The transfer function of sRGB roughly corresponds to a power function with a gamma of 2.2.

FRAMEBUFFERS

OpenGL assumes framebuffer color components are stored in a linear color space. In particular, framebuffer blending is a linear operation.

This extension adds a framebuffer capability for sRGB framebuffer update and blending. When blending is disabled but the new sRGB updated mode is enabled (assume the framebuffer supports the capability), high-precision linear color component values for red, green, and blue generated by fragment coloring are encoded for sRGB prior to being written into the framebuffer. When blending is enabled along with the new sRGB update mode, red, green, and blue framebuffer color components are treated as sRGB values that are converted to linear color values, blended with the high- precision color values generated by fragment coloring, and then the blend result is encoded for sRGB just prior to being written into the framebuffer.

TEXTURES

Conventional texture formats assume a linear color space. So for a conventional internal texture format such as GL_RGB8, the 256 discrete values for each 8-bit color component map linearly and uniformly to the [0,1] range.
