public ShearWarpColor(ModelImage kImage,
                      int iFinalBound,
                      int[] aiFinal)
```
    Create a color renderer. The input color channel type is 'byte', a signed 8-bit quantity, but the data represents unsigned 8-bit values.
    
    Parameters:
    
    kImage - the 3D image
    
    iFinalBound - the dimension of the square 2D renderer image
    
    aiFinal - The 2D rendered image. The image is 24-bit RGB color, each pixel stored as a 32-bit integer. The 8 most significant bits are ignored. The blue channel is stored in the 8 least significant bits. The green channel is in the next 8 bits adjacent to the blue bits. The red channel is in the next 8 bits adjacent to the green channel.

  - hasInputData
```
public boolean hasInputData()
```
    Return indication as to whether or not the input image data has been specified yet.
    
    Specified by:
    
    hasInputData in interface RendererInterfaceColor
    
    Specified by:
    
    hasInputData in class Renderer
    
    Returns:
    
    boolean True if the input image data has been specified.

    Return indication as to whether or not a map has been defined for mapping input colors to intensity.
    
    Specified by:
    
    hasInputMap in interface RendererInterfaceColor
    
    Returns:
    
    boolean True if such a map has been defined.

                     byte[] acImageB,
                     byte[] acImageA)
```
    Specify the input volume to use for rendering. The image data stored in order of slice indices, each slice stored in row-major order. That is, slice z=0 is stored first, slice z=1 is stored next, and so on. In slice z=0, the y=0 row is stored first, the y=1 row is stored next, and so on.
    
    Specified by:
    
    setInput in interface RendererInterfaceColor
    
    Parameters:
    
    acImageR - byte[] Array of byte red values for volume.
    
    acImageG - byte[] Array of byte green values for volume.
    
    acImageB - byte[] Array of byte blue values for volume.
    
    acImageA - byte[] Array of byte alpha values for volume.
  - setInputMap
```
public void setInputMap(RendererMapColor kMap)
```
    Specify the lookup table to use for mapping input RGB colors to intensity.
    
    Specified by:
    
    setInputMap in interface RendererInterfaceColor
    
    Parameters:
    
    kMap - Look up table for mapping the color values to intensity.
  - finalize

protected void finalize()
                 throws java.lang.Throwable
```
    Calls dispose.
    
    Overrides:
    
    finalize in class ShearWarpRenderer
    
    Throws:
    
    java.lang.Throwable - DOCUMENT ME!
  - mapIntermediateToFinal

protected void mapIntermediateToFinal()
```
    Map the intermediate images to the final color image.
    
    Specified by:
    
    mapIntermediateToFinal in class ShearWarpRenderer
  - resampleAll
```
protected void resampleAll(int iDS)
```
    Resample all the slices for the current permuted volume data.
    
    Overrides:
    
    resampleAll in class ShearWarpRenderer
    
    Parameters:
    
    iDS - The number of slices to increment during the resampling phase. The value should be one or larger. If one, all slices of the volume data are resampled. If two, only every other slice is resampled. An input larger than one is used to allow fast rendering during rotation of the volume data. Once the rotation terminates, a composite with input of one should be called.
