image
Specify the image unit from which to load a texel.
P
Specify the coordinate from which to load the texel.
imageLoad
loads the texel at the coordinate P
from the image
unit image
. When image
and P
identify
a valid texel, the bits used to represent the selected texel in memory are converted to a vec4, ivec4, or uvec4
in the manner described in the OpenGL ES Specification and returned.
