Some parameters from the parent class are interpreted strictly in this class. <i>Required parameters during a read:</i> <ul> <li>An open and connected <CODE>SeConnection</CODE> used to suck out data from ArcSDE for this image read operation.(setConnection())</li> <li>A <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/util/HashMap.html" title="class or interface in java.util"><CODE>HashMap</CODE></A> with <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Integer.html" title="class or interface in java.lang"><CODE>Integer</CODE></A> keys equal to the SeObjectId.longValue() of each <CODE>SeRasterBand</CODE> which is to be read. Values for each key should be the integer value of the band in the output image to which the given SeRasterBand should be copied.<br/><br/>For example, if your ArcSDE Raster contains four bands with SeRasterBand.getId().longValue()s of 234,235,236 and 237, and you wish to map those bands to the R,G,B and A bands in your ARGB image, you should create a map as follows:<br/> Map m = new HashMap();<br/> m.put(new Integer(234), new Integer(1));<br/> m.put(new Integer(234), new Integer(2));<br/> m.put(new Integer(234), new Integer(3));<br/> m.put(new Integer(234), new Integer(0));<br/> <br/> Note that the band indexes you choose will depend on the type of BufferedImage you're writing to. A BufferedImage of type BufferedImage.TYPE_INT_ARGB has its bands in the order "Alpha (0), Red (1), Green (2), Blue (3)". A BufferedImage of type BufferedImage.TYPE_3BYTE_BGR has its bands in the order "Blue (0), Green (1), Red (2)".<br/> </li> <li>A (possibly null) <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/BufferedImage.html" title="class or interface in java.awt.image"><CODE>BufferedImage</CODE></A>, passed in via the 'setDestination()' method. Make sure your bandmapper and this image contain the same number of bands, and that you've mapped your output appropriately.<br/> <i><b>If you leave this parameter null, a BufferedImage.TYPE_INT_ARGB will be created, of exactly the size to cover your requested source region</b></i></li> <li>An int[] of requested source bands from ArcSDE, set via setSourceBands(). ArcSDE expects the int[] to have the same size as the number of bands you're requesting. The first band should be numbered '1', the second '2', etc. So, to request the second, third and fourth bands in a raster, use a setSourceBands() call like the following:<br/> param.setSourceBands(new int[] { 2, 3, 4 });<br/> <b>A source band with the value of zero won't work! start with 1!</b> </li> <li>A <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/Rectangle.html" title="class or interface in java.awt"><CODE>Rectangle</CODE></A> defining the source area of the raster level you wish to render. This is expressed as though the entire raster level was one big seamless image of size wxh, with the origin in the upper left corner. So, to request a tiny bit of the raster level, simply set your sourceRegion accordingly and only the proper bit of the raster will be loaded.</li> </ul><P><P><DL><DT><B>Author:</B></DT>
