The affine transform will be computed automatically from the information specified by the <A HREF="../../../../../org/geotools/referencing/operation/builder/GridToEnvelopeMapper.html#setGridRange(org.opengis.coverage.grid.GridRange)"><CODE>setGridRange</CODE></A> and <A HREF="../../../../../org/geotools/referencing/operation/builder/GridToEnvelopeMapper.html#setEnvelope(org.opengis.spatialschema.geometry.Envelope)"><CODE>setEnvelope</CODE></A> methods, which are mandatory. All other setter methods are optional hints about the affine transform to be created. This builder is convenient when the following conditions are meet: <p> <ul> <li><p>Pixels coordinates (usually (<var>x</var>,<var>y</var>) integer values inside the rectangle specified by the grid range) are expressed in some coordinate reference system known at compile time. This is often the case. For example the CRS attached to <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> has always (column, row) axis, with the origin (0,0) in the upper left corner, and row values increasing down.</p></li> <li><p>"Real world" coordinates (inside the envelope) are expressed in arbitrary <em>horizontal</em> coordinate reference system. Axis directions may be (North, West), or (East, North), <cite>etc.</cite>.</p></li> </ul> <p> In such case (and assuming that the image's CRS has the same characteristics than the <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>'s CRS described above): <p> <ul> <li><p><A HREF="../../../../../org/geotools/referencing/operation/builder/GridToEnvelopeMapper.html#setSwapXY(boolean)"><CODE>swapXY</CODE></A> shall be set to if the "real world" axis order is (North, East) instead of (East, North). This axis swapping is necessary for mapping the (column, row) axis order associated to the image CRS.</p></li> <li><p>In addition, the "real world" axis directions shall be reversed (by invoking <code><A HREF="../../../../../org/geotools/referencing/operation/builder/GridToEnvelopeMapper.html#reverseAxis(int)">reverseAxis</A>(dimension)</code>) if their direction is <CODE>WEST</CODE> (<var>x</var> axis) or <CODE>NORTH</CODE> (<var>y</var> axis), in order to get them oriented toward the <CODE>EAST</CODE> or <CODE>SOUTH</CODE> direction respectively. The later may seems unatural, but it reflects the fact that row values are increasing down in an <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/BufferedImage.html" title="class or
