Specify the image unit into which to store data.


Specify the coordinate at which to store the data.


When present, specifies the sample within the image to store into.


Specifies the data of which to take the minimum with that stored in the image.


imageAtomicMax atomically computes a new value by finding the maximum of the value of data and the contents of the texel at coordinate P and sample in the image bound to uint image, stores that value into the image and returns the original value.
