| <h2>Description</h2> |
| <p> |
| OpenCL supports 2D image memory objects that can be read or written by kernels. Reads |
| and writes to the same 2D image memory object are not supported in a kernel. OpenCL |
| also supports reads to 3D image memory objects in kernels. Writes to a 3D image memory |
| object are not supported unless the <code class="function">cl_khr_3d_image_writes</code> |
| extension is implemented. Reads and writes to the same 3D image memory object are |
| not allowed in a kernel. |
| </p> |
| <p> |
| An application that wants to use this extension to write to 3D image memory objects |
| will need to include the <code class="code">#pragma OPENCL EXTENSION cl_khr_3d_image_writes : |
| enable</code> directive in the OpenCL program source. |
| </p> |
| <p> |
| The <a class="citerefentry" href="write_image3d.html"><span class="citerefentry"><span class="refentrytitle">built-in 3d image |
| write functions</span></span></a> are implemented by the |
| <code class="function">cl_khr_3d_image_writes</code> extension. |
