Quoted from the docs:<p>	``The following options are supported by the encoder:	<table>	<tr>		<td>imgareatlx=x</td>		<td> Set the x-coordinate of the top-left corner			of the image area to x.</td>	</tr>	<tr>		<td>imgareatly=y</td>		<td>Set the y-coordinate of the top-left corner			of the image area to y.</td>	</tr>	<tr>		<td>tilegrdtlx=x</td>		<td>Set the x-coordinate of the top-left corner			of the tiling grid to x.</td>	</tr>	<tr>		<td>tilegrdtly=y</td>		<td>Set the y-coordinate of the top-left corner			of the tiling grid to y.</td>	</tr>	<tr>		<td>tilewidth=w</td>		<td>Set the nominal tile width to w.</td>	</tr>	<tr>		<td>tileheight=h</td>		<td>Set the nominal tile height to h.</td>	</tr>	<tr>		<td>prcwidth=w</td>		<td>Set the precinct width to w. The argument w must be an			integer power of two. The default value is 32768.</td>	</tr>	<tr>		<td>prcheight=h</td>		<td>Set the precinct height to h. The argument h must be an			integer power of two. The default value is 32768.</td>	</tr>	<tr>		<td>cblkwidth=w</td>		<td>Set the nominal code block width to w. The argument			w must be an integer power of two.			The default value is 64.</td>	</tr>	<tr>		<td>cblkheight=h</td>		<td>Set the nominal code block height to h. The argument			h must be an integer power of two.			The default value is 64.</td>	</tr>	<tr>		<td>mode=m</td>		<td>Set the coding mode to m. The argument m must have			one of the following values:			<center><table border>			<tr>				<th>Value</th>	<th>Description</th>			</tr>			<tr>				<td>int</td>	<td>integer mode</td>			</tr>			<tr>				<td>real</td>	<td>real mode</td>			</tr>			</table></center>		If lossless coding is desired, the integer mode must		be used. By default, the integer mode is employed. The		choice of mode also determines which multicomponent		and wavelet transforms (if any) are employed.</td>	</tr>	<tr>		<td>rate=r</td>		<td>Specify the target rate. The argument r is a positive			real number. Since a rate of one corresponds			to no compression, one should never need			to explicitly specify a rate greater than one.			By default, the target rate is considered			to be infinite.</td>	</tr>	<tr>		<td>ilyrrates=[, ,. . . ,      ]</td>				<td>Specify the rates for any intermediate layers.			The argument to this option is a comma separated			list of N rates. Each rate is a positive real number.			The rates must increase monotonically. The last	rate			in the list should be less than or equal to the			overall rate (as specified with the rate option).</td>	</tr>		<tr>		<td>prg=p</td>		<td>Set the progression order to p. The argument			p must have one of the following values:			<center><table border>			<tr>				<th>Value</th>	<th>Description</th>			</tr>			<tr>				<td>lrcp</td>				<td>layer-resolution-component-position	(LRCP)				progressive (i.e., rate scalable)</td>			</tr>			<tr>				<td>rlcp</td>				<td>resolution-layer-component-position	(RLCP)				progressive (i.e., resolution scalable)</td>			</tr>			<tr>				<td>rpcl</td>				<td>resolution-position-component-layer (RPCL)					progressive</td>			</tr>			<tr>				<td>pcrl</td>				<td>position-component-resolution-layer (PCRL)					progressive</td>			</tr>			<tr>				<td>cprl</td>				<td>component-position-resolution-layer (CPRL)					progressive</td>			</tr>			</table></center>		By default, LRCP progressive ordering is employed.		Note that the RPCL and PCRL progressions are not valid		for all possible image geometries.		(See standard for more details.)</td>	</tr>		<tr>		<td>nomct</td>		<td>Disallow the use of any multicomponent transform.</td>	</tr>	<tr>		<td>numrlvls=n</td>		<td>Set the number of resolution levels to n. The argument			n must be an integer that is greater than or equal			to one. The default value is 6.</td>	</tr>	<tr>		<td>sop</td>		<td>Generate SOP marker segments.</td>	</tr>	<tr>		<td>eph</td>		<td>Generate EPH marker segments.</td>	</tr>	<tr>		<td>lazy</td>		<td>Enable lazy coding mode (a.k.a. arithmetic coding			bypass).</td>	</tr>	<tr>		<td>termall</td>		<td>Terminate all coding passes.</td>	</tr>	<tr>		<td>segsym</td>		<td>Use segmentation symbols.</td>	</tr>	<tr>		<td>vcausal</td>		<td>Use vertically stripe causal contexts.</td>	</tr>	<tr>		<td>pterm</td>		<td>Use predictable termination.</td>	</tr>	<tr>		<td>resetprob</td>		<td>Reset the probability models after each coding pass.<td>	</tr>		<tr>		<td>numgbits=n</td>		<td>Set the number of guard bits to n.''</td>	</tr>	</table></ul><h2>See Also:</h2><ul><li> Implemented as <tt>gdal/frmts/jpeg2000/jpeg2000dataset.cpp</tt>.<p><li> You need modified JasPer library to build this driver with GeoJP2 supportenabled.
