Constructor Details

ShearWarpIntensity

public ShearWarpIntensity(ModelImage kImage,
 int iFinalBound,
 int[] aiFinal)

Create an intensity renderer.

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.

Method Details

disposeLocal

public void disposeLocal()

Clean memory.

Overrides:

disposeLocal in class ShearWarpRenderer

hasInputData

public boolean hasInputData()

Return indication as to whether or not the input image data has been specified yet.

Specified by:

hasInputData in interface RendererInterfaceIntensity

Specified by:

hasInputData in class Renderer

Returns:

boolean True if the input image data has been specified.

hasInputMap

public boolean hasInputMap()

Return indication as to whether or not a LUT to use for mapping input intensity values to colors has been specified.

Specified by:

hasInputMap in interface RendererInterfaceIntensity

Returns:

boolean True if such a LUT has been defined.

setInput

public void setInput(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 RendererInterfaceIntensity

Parameters:

acImageB - byte[] Array of byte intensity values for volume.

acImageA - byte[] Array of byte alpha values for volume.

setInputMap

public void setInputMap(RendererMapIntensity kMap)

Specify the lookup table to use for mapping input intensity values to colors.

Specified by:

setInputMap in interface RendererInterfaceIntensity

Parameters:

kMap - Look up table for mapping the intensity values to colors.

finalize

protected void finalize()
                 throws Throwable

Calls disposeLocal to clean up memory, and then call super.finalize();

Overrides:

finalize in class ShearWarpRenderer

Throws:

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.
