Image data to load by an image instruction.
*Size:* depends on :ref:`dmask<amdgpu_synid_dmask>`, :ref:`tfe<amdgpu_synid_tfe>` and :ref:`d16<amdgpu_synid_d16>`:
* :ref:`dmask<amdgpu_synid_dmask>` may specify from 1 to 4 data elements. Each data element occupies either 32 bits or 16 bits depending on :ref:`d16<amdgpu_synid_d16>`.
* :ref:`d16<amdgpu_synid_d16>` specifies that data elements in registers are packed; each value occupies 16 bits.
* :ref:`tfe<amdgpu_synid_tfe>` adds 1 dword if specified.
*Operands:* :ref:`v<amdgpu_synid_v>`, :ref:`a<amdgpu_synid_a>`
