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.
