<h2>Description</h2>

<p>

Pixels can be drawn using a function that blends

the incoming (source) RGBA values with the RGBA values

that are already in the frame buffer (the destination values).

Blending is initially disabled.

Use <a class="citerefentry" href="glEnable"><span class="citerefentry"><span class="refentrytitle">glEnable</span></span></a> and <a class="citerefentry" href="glDisable"><span class="citerefentry"><span class="refentrytitle">glDisable</span></span></a> with argument <code class="constant">GL_BLEND</code>

to enable and disable blending.

</p>

<p>

<code class="function">glBlendFuncSeparate</code> defines the operation of blending when it is enabled.

<em class="parameter"><code>srcRGB</code></em> specifies which method is used to scale the

source RGB-color components.

<em class="parameter"><code>dstRGB</code></em> specifies which method is used to scale the

destination RGB-color components.

Likewise, <em class="parameter"><code>srcAlpha</code></em> specifies which method is used to scale the source alpha

color component, and <em class="parameter"><code>dstAlpha</code></em> specifies which method is used to scale the

destination alpha component.

The possible methods are described in the following table.

Each method defines four scale factors,

one each for red, green, blue, and alpha.

</p>

In the table and in subsequent equations, source and destination

color components are referred to as

</p>

<p>

Prior to blending, unsigned normalized fixed-point color components undergo

an implied conversion to floating-point using equation 2.1. This conversion must

leave the values 0 and 1 invariant. Blending computations are treated as if carried

out in floating-point and will be performed with a precision and dynamic range no

lower than that used to represent destination components.

If the value of <code class="constant">GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING</code> for the

framebuffer attachment corresponding to the destination buffer is <code class="constant">GL_SRGB</code>,

the R, G, and B destination color values (after conversion from fixed-point

to floating-point) are considered to be encoded for the sRGB color space and

hence must be linearized prior to their use in blending. Each R, G, and B component

is converted in the same fashion described for sRGB texture components.
