image+ Specify the image unit from which to load a texel. +
P+ Specify the coordinate from which to load the texel. +
sample+ When present, specifies the sample within the image to load +
+ imageLoad loads the texel at the coordinate P from the image
+ unit image. For multi-sample loads, the sample number is given by sample. When
+ image, P, sample 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
+ Specification and returned.
