Arguments

   REJECTABLE

      Rejects features if this keyword is specified.

      Range: N/A

   <offset> 
   
      Real Value  
      
      The offset value applied to all the features dimensions.
   
   <xOffset>   
   
      Real Value  
      
      The X offset applied to the feature.
   
   <yOffset>   
   
      Real Value  
      
      The Y offset applied to the feature.
   
   <zOffset>   
   
      Real Value  
      
      The Z offset applied to the feature.

    <radius>

      Real Value

      The distance to offset the feature.

    <angle>

      Real Value

      Angle, in degrees CCW from the positive X-axis.

    <azimuth>

      Real Value

      Angle, in degrees CW from the positive Y-axis.

    <altitude>

      Real Value

      Angle, in degrees from the XY plane. The angle between the XY plane and the positive Z-axis is 90 degrees.


Description

   This command adds the offsets to the feature's coordinates. If just one value is 
   specified, then the feature will be offset by that value in all of its dimensions. 
   (2D features will be offset in X and Y, and 3D features will be offset in X, Y and
   Z.) If two values are specified, then X and Y are offset as specified and the Z 
   component is left untouched. If three real values are specified, then X, Y, and Z 
   are offset as specified.

   If three values are specified, with the first value being POLAR, then the feature's 
   coordinates will be offset using polar coordinates, with the second and third values 
   representing radius and angle, respectively.

   If four values are specified, with the first value being SPHERICAL, then the feature's 
   coordinates will be offset using spherical coordinates, with the second, third, and 
   fourth values representing radius, azimuth, and altitude, respectively.

   If given a non-zero Z offset value, all geometries will be treated as 3D and offset from 
   a value of z=0. If any 2D geometries are encountered, a warning will be logged and it will 
   be forced to 3D with a z value of zero. Any collection geometries containing 2D components 
   will have those components forced to 3D with z=0 to ensure consistent dimensions. 

   This command also supports raster features and supports sub-selection of 
   raster bands and palettes.
