| The built-in functions defined in this section |

| specific function calls that read from and/or write to specific locations in the image. |
| </p> |
| <p> |
| Note that image writes to sRGB images are only supported if the |
| <a class="citerefentry" href="cl_khr_srgb_image_writes.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_srgb_image_writes</span></span></a> |
| extension is supported; |
| otherwise the behavior of writing to a sRGB image is undefined. |
| </p> |
| <p> |
| Image memory objects that are being read by a kernel should be declared with the <a class="citerefentry" href="accessQualifiers.html"><span class="citerefentry"><span class="refentrytitle">read_only</span></span></a> |
| qualifier. <code class="function">write_image</code> calls to image memory objects declared with the |
| <a class="citerefentry" href="accessQualifiers.html"><span class="citerefentry"><span class="refentrytitle">read_only</span></span></a> |

| qualifier. |
| </p> |

| The <code class="function">read_image</code> calls returns a four component floating-point, integer or |
| unsigned integer color value. The color values returned by <code class="function">read_image</code> |
| are identified as <code class="code">x, y, z, w</code> where <code class="code">x</code> refers to the red component, |
| <code class="code">y</code> refers to the green component, <code class="code">z</code> refers to the blue component |

| <p> |
| The samplerless read image functions behave exactly as the corresponding read |

| The built-in image read functions will perform |
| sRGB to linear RGB conversions if the image is |

| to <code class="function">write_image{f|i|ui}</code>. The unmapped components will be set |
| to <code class="constant">0.0</code> for red, green and blue channels and will be set to |
| <code class="constant">1.0</code> for the alpha channel. |

| A kernel that uses a sampler with the <code class="constant">CL_ADDRESS_CLAMP</code> addressing |
| mode with multiple images may result in additional samplers being used internally |
| by an implementation. If the same sampler is used with multiple images called via |
| <code class="function">read_image{f|i|ui}</code>, then it is possible that an implementation may |
| need to allocate an additional sampler to handle the different border color values that |
| may be needed depending on the image formats being used. These implementation allocated |
| samplers will count against the maximum sampler values supported by the device and given by |
| <code class="constant">CL_DEVICE_MAX_SAMPLERS</code>. Enqueuing a kernel that requires more samplers |
| than the implementation can support will result in a <code class="constant">CL_OUT_OF_RESOURCES</code> |
| error being returned. |
