imageLoad 3G
imageLoad load a single texel from an image

## Declaration

gvec4 `imageLoad` gimage1D image int P gvec4 `imageLoad` gimage2D image ivec2 P gvec4 `imageLoad` gimage3D image ivec3 P gvec4 `imageLoad` gimage2DRect image ivec2 P gvec4 `imageLoad` gimageCube image ivec3 P gvec4 `imageLoad` gbufferImage image int P gvec4 `imageLoad` gimage1DArray image ivec2 P gvec4 `imageLoad` gimage2DArray image ivec3 P gvec4 `imageLoad` gimageCubeArray image ivec3 P gvec4 `imageLoad` gimage2DMS image ivec2 P int sample gvec4 `imageLoad` gimage2DMSArray image ivec3 P int sample

## Parameters

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

## Description

`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.
