<!-- ================================ DESCRIPTION -->
<refsect1 id="description"><title>Description</title>
<para>
<function>write_imagef</function> can only be used with image objects created with
<varname>image_channel_data_type</varname> set to one of the pre-defined packed formats
or set to <constant>CL_SNORM_INT8</constant>, <constant>CL_UNORM_INT8</constant>,
<constant>CL_SNORM_INT16</constant>, <constant>CL_UNORM_INT16</constant>,
<constant>CL_HALF_FLOAT</constant>, or <constant>CL_FLOAT</constant>. Appropriate data
format conversion will be done to convert channel data from a floating-point value to
actual data format in which the channels are stored.
</para>
<para>
<function>write_imagei</function> functions can only be used with image objects
created with <varname>image_channel_data_type</varname> set to one of the following
values: <constant>CL_SIGNED_INT8</constant>, <constant>CL_SIGNED_INT16</constant>,
or <constant>CL_SIGNED_INT32</constant>.

<function>write_imageui</function> functions can only be used with image objects
created with <varname>image_channel_data_type</varname> set to one of the following
values: <constant>CL_UNSIGNED_INT8</constant>, <constant>CL_UNSIGNED_INT16</constant>,

<para>
The <function>write_imageh</function> functions are enabled when the half type is
supported and can only be used with image objects created with
<varname>image_channel_data_type</varname> set to one of the pre-defined packed formats
or set to <constant>CL_SNORM_INT8</constant>, <constant>CL_UNORM_INT8</constant>,
<constant>CL_SNORM_INT16</constant>, <constant>CL_UNORM_INT16</constant> or

to convert channel data from a floating-point value to actual data format in which
the channels are stored.

<bridgehead>Functions that take image1d_t or image1d_buffer_t</bridgehead>
<para>
The functions that take image1d_t or image1d_buffer_t write the <varname>color</varname>
value to the location specified by <varname>coord</varname> in the 1D image or 1D image buffer
object specified by <varname>image</varname>. Appropriate data format conversion to the
specified image format is done before writing the color value. <varname>coord</varname> is
considered to be unnormalized coordinates and must be in the range 0... image width - 1.
</para>
<para>
for functions taking image1d_t or image1d_buffer_t, the behavior of
<function>write_imagef</function>, <function>write_imagei</function>,
<function>write_imageui</function>, and <function>write_imageh</function> for image
objects created with <varname>image_channel_data_type</varname> values not specified in
the description above or with coordinate values that are not in the range (0... image
width - 1), is undefined.
</para>
<bridgehead>Functions that take image1d_array_t</bridgehead>
<para>
The functions that take image1d_array_t write the <varname>color</varname> value to the location specified by
<emphasis>coord.x</emphasis> in the 1D image identified by <emphasis>coord.y</emphasis>
in the 1D image array specified by <varname>image</varname>. Appropriate data format
conversion to the specified image format is done before writing the color value.
<emphasis>coord.x</emphasis> and <emphasis>coord.y</emphasis> are considered to be
unnormalized coordinates and must be in the range 0 &hellip; image width - 1 and 0 &hellip;
image number of layers - 1.
</para>
<para>
For functions taking image1d_array_t, the behavior of <function>write_imagef</function>,
<function>write_imagei</function> and <function>write_imageui</function> for image
objects created with <varname>image_channel_data_type</varname> values not specified
