| It is currently a requirement that the <code class="varname">src_image</code> and <code class="varname">dst_image</code> image memory objects for <code class="function">clEnqueueCopyImage</code> must have the exact same image format (i.e. the <a class="citerefentry" href="cl_image_format.html"><span class="citerefentry"><span class="refentrytitle">cl_image_format</span></span></a> descriptor specified when <code class="varname">src_image</code> and <code class="varname">dst_image</code> are created must match). |
| </p> |
| <p> |
| <code class="varname">src_image</code> and <code class="varname">dst_image</code> can be 2D or 3D image objects |
| allowing us to perform the following actions: |
