NAME
       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.
