.SH "NAME"
clEnqueueFillImage \- Enqueues a command to fill an image object with a specified color\&.

.SH "PARAMETERS"
.PP
\fI command_queue \fR
.RS 4
Refers to the command\-queue in which the fill command will be queued\&. The OpenCL context associated with
\fIcommand_queue\fR
and image must be the same\&.
.RE
.PP
\fI image \fR
.RS 4
A valid image object\&.
.RE
.PP
\fI fill_color \fR
.RS 4
The fill color\&. The fill color is a four component RGBA floating\-point color value if the
\fIimage\fR
channel data type is not an unnormalized signed and unsigned integer type, is a four component signed integer value if the
\fIimage\fR
channel data type is an unnormalized signed integer type and is a four component unsigned integer value if the
\fIimage\fR
channel data type is an unormalized unsigned integer type\&. The fill color will be converted to the appropriate image channel format and order associated with
\fIimage\fR\&.
.RE
.PP
\fI origin \fR
.RS 4
Defines the (\fIx, y, z\fR) offset in pixels in the 1D, 2D, or 3D image, the (\fIx, y\fR) offset and the image index in the image array or the (x) offset and the image index in the 1D image array\&. If
\fIimage\fR
is a 2D image object,
\fIorigin\fR[2] must be 0\&. If
\fIimage\fR
is a 1D image or 1D image buffer object,
\fIorigin\fR[1] and
\fIorigin\fR[2] must be 0\&. If
\fIimage\fR
is a 1D image array object,
\fIorigin\fR[2] must be 0\&. If
\fIimage\fR
is a 1D image array object,
\fIorigin\fR[1] describes the image index in the 1D image array\&. If
\fIimage\fR
is a 2D image array object,
\fIorigin\fR[2] describes the image index in the 2D image array\&.
.RE
.PP
\fI region \fR
.RS 4
Defines the (\fIwidth, height, depth\fR) in pixels of the 1D, 2D or 3D rectangle, the (\fIwidth, height\fR) in pixels of the 2D rectangle and the number of images of a 2D image array or the (\fIwidth\fR) in pixels of the 1D rectangle and the number of images of a 1D image array\&. If
\fIimage\fR
is a 2D image object,
\fIregion\fR[2] must be 1\&. If
\fIimage\fR
is a 1D image or 1D image buffer object,
\fIregion\fR[1] and
\fIregion\fR[2] must be 1\&. If
\fIimage\fR
is a 1D image array object,
\fIregion\fR[2] must be 1\&.
.RE
.PP
\fI event_wait_list ,\fR \fI num_events_in_wait_list \fR
.RS 4
Specify events that need to complete before this particular command can be executed\&. If
\fIevent_wait_list\fR
is NULL, then this particular command does not wait on any event to complete\&. If
\fIevent_wait_list\fR
is NULL,
\fInum_events_in_wait_list\fR
must be 0\&. If
\fIevent_wait_list\fR
is not NULL, the list of events pointed to by
\fIevent_wait_list\fR
must be valid and
\fInum_events_in_wait_list\fR
must be greater than 0\&. The events specified in
\fIevent_wait_list\fR
act as synchronization points\&. The context associated with events in
\fIevent_wait_list\fR
and
\fIcommand_queue\fR
must be the same\&. The memory associated with
\fIevent_wait_list\fR
can be reused or freed after the function returns\&.
.RE
.PP
\fI event \fR
.RS 4
Returns an event object that identifies this particular write command and can be used to query or queue a wait for this particular command to complete\&.
\fIevent\fR
can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete\&.
\fBclEnqueueBarrierWithWaitList\fR(3clc)
can be used instead\&. If the
\fIevent_wait_list\fR
and the
\fIevent\fR
arguments are not NULL, the
\fIevent\fR
argument should not refer to an element of the
\fIevent_wait_list\fR
array\&.
.RE
.SH "NOTES"
.PP
The usage information which indicates whether the memory object can be read or written by a kernel and/or the host and is given by the
\fBcl_mem_flags\fR
argument value specified when
\fIimage\fR
is created is ignored by
\fBclEnqueueFillImage\fR\&.
.SH "ERRORS"
.PP
\fBclEnqueueFillImage\fR
return
CL_SUCCESS
