Field Detail

b

public byte[] b

The brightness of each voxel as a byte (0-225). This brightness derives from the HSB color model.

index

public byte[] index

The index value for each voxel, if any.

sliceArray

public java.lang.Object[] sliceArray

The slices for this volume with the actual RGB data.

Constructor Detail

VolumeRGB

public VolumeRGB(int width,
                 int height,
                 int depth,
                 double aspectx,
                 double aspecty,
                 double aspectz)

Creates an RGB volume of defined size and aspect ratio.

Parameters:

Method Detail

get

public java.lang.Object get(int x,
                            int y,
                            int z)

Get the brightness of the voxel at x,y,z as an integer between 0-255. The brightness is derived from the HSB color model.

Overrides:

get in class Volume

Parameters:

x - the x position of the voxel

y - the y position of the voxel

z - the z position of the voxel

Returns:

an Integer with the brightness converted to a value between 0 (0.0) and 255 (1.0)

set

public void set(java.lang.Object value,
                int x,
                int y,
                int z)

Set the brightness of the voxel at x,y,z as an integer between 0-255. The brightness is derived from the HSB color model.

Overrides:

set in class Volume

Parameters:

value - a Number with the brightness between 0 (0.0) and 255 (1.0)

x - the x position of the voxel

y - the y position of the voxel

z - the z position of the voxel

load

protected void load(java.lang.Object[] sliceArray,
                    int start)

Fill the brightness volume b with the int[] slices, starting at slice start.

Parameters:

sliceArray - an array of Objects, which are byte [] with the index value for each voxel.

start - the first slice to be loaded (starting with slice 1).

getImageStack

public ij.ImageStack getImageStack()

Make an ImageJ imagestack from the brightness info. For debugging purposes only.

intToHSB

public static float[] intToHSB(float[] hsb,
