Constructor Detail

ImageStack

public ImageStack()

Default constructor.

ImageStack

public ImageStack(int width,
                  int height)

Creates a new, empty image stack.

ImageStack

public ImageStack(int width,
                  int height,
                  int size)

Creates a new image stack with a capacity of 'size'.

ImageStack

public ImageStack(int width,
                  int height,
                  java.awt.image.ColorModel cm)

Creates a new, empty image stack.

Method Detail

addSlice

public void addSlice(java.lang.String sliceLabel,
                     java.lang.Object pixels)

Adds an image in the forma of a pixel array to the end of the stack.

addUnsignedShortSlice

public void addUnsignedShortSlice(java.lang.String sliceLabel,
                                  java.lang.Object pixels)

Deprecated. Short images are always unsigned.

addSlice

public void addSlice(java.lang.String sliceLabel,
                     ImageProcessor ip)

Adds the image in 'ip' to the end of the stack.

addSlice

public void addSlice(java.lang.String sliceLabel,
                     ImageProcessor ip,
                     int n)

Adds the image in 'ip' to the stack following slice 'n'. Adds the slice to the beginning of the stack if 'n' is zero.

deleteSlice

public void deleteSlice(int n)

Deletes the specified slice, were 1<=n<=nslices.

deleteLastSlice

public void deleteLastSlice()

Deletes the last slice in the stack.

getWidth

public int getWidth()

getHeight

public int getHeight()

setRoi

public void setRoi(java.awt.Rectangle roi)

getRoi

public java.awt.Rectangle getRoi()

update

public void update(ImageProcessor ip)

Updates this stack so its attributes, such as min, max, calibration table and color model, are the same as 'ip'.

getPixels

public java.lang.Object getPixels(int n)

Returns the pixel array for the specified slice, were 1<=n<=nslices.

setPixels

public void setPixels(java.lang.Object pixels,
                      int n)

Assigns a pixel array to the specified slice, were 1<=n<=nslices.

getImageArray

public java.lang.Object[] getImageArray()

Returns the stack as an array of 1D pixel arrays. Note that the size of the returned array may be greater than the number of slices currently in the stack, with unused elements set to null.

getSize

public int getSize()

Returns the number of slices in this stack.

getSliceLabels

public java.lang.String[] getSliceLabels()

Returns the slice labels as an array of Strings. Note that the size of the returned array may be greater than the number of slices currently in the stack. Returns null if the stack is empty or the label of the first slice is null.

getSliceLabel

public java.lang.String getSliceLabel(int n)

Returns the label of the specified slice, were 1<=n<=nslices. Returns null if the slice does not have a label. For DICOM and FITS stacks, labels may contain header information.

public java.lang.String getShortSliceLabel(int n)

Returns a shortened version (up to the first 60 characters or first newline and suffix removed) of the label of the specified slice. Returns null if the slice does not have a label.

setSliceLabel

public void setSliceLabel(java.lang.String label,
