  public CellGrid(CellGrid grid)

Method Detail

• numDimensions

  public int numDimensions()

• getGridDimensions

  public long[] getGridDimensions()

• gridDimensions

  public void gridDimensions(long[] s)

• gridDimension

  public long gridDimension(int d)

• getImgDimensions

  public long[] getImgDimensions()

  Get the number of pixels in each dimension as a new long[]. Note, that this is the number of pixels in all cells combined, not the number of cells!

• imgDimensions

  public void imgDimensions(long[] dimensions)

  Write the number of pixels in each dimension into long[]. Note, that this is the number of pixels in all cells combined, not the number of cells!

  Parameters:

  dimensions -

• imgDimension

  public long imgDimension(int d)

  Get the number of pixels in a given dimension d. Note, that this is the number of pixels in all cells combined, not the number of cells!

  Parameters:

  d -

• cellDimensions

  public void cellDimensions(int[] dimensions)

  Write the number of pixels in a standard cell in each dimension into long[]. Cells on the max border of the image may be cut off and have different dimensions.

  Parameters:

  dimensions -

• cellDimension

  public int cellDimension(int d)

  Get the number of pixels in a standard cell in a given dimension d. Cells on the max border of the image may be cut off and have different dimensions.

  Parameters:

  d -

• getCellDimensions

  public void getCellDimensions(long index,
                                long[] cellMin,
                                int[] cellDims)

  From the index of a cell in the grid, compute the image position of the first pixel of the cell (the offset of the cell in image coordinates) and the dimensions of the cell. The dimensions will be the standard cellDimensions unless the cell is at the border of the image in which case it might be truncated.

  Note, that this method assumes that the cell grid has flat iteration order. It this is not the case, use getCellDimensions(long[], long[], int[]).

  Parameters:

  index - flattened grid coordinates of the cell.

  cellMin - offset of the cell in image coordinates are written here.

  cellDims - dimensions of the cell are written here.

• getCellDimensions

  public void getCellDimensions(long[] cellGridPosition,
                                long[] cellMin,
                                int[] cellDims)

  From the position of a cell in the grid, compute the image position of the first pixel of the cell (the offset of the cell in image coordinates) and the dimensions of the cell. The dimensions will be the standard cellDimensions unless the cell is at the border of the image in which case it might be truncated.

  Parameters:

  cellGridPosition - grid coordinates of the cell.

  cellMin - offset of the cell in image coordinates are written here.

  cellDims - dimensions of the cell are written here.

• getCellDimension

  public int getCellDimension(int d,
                              long cellGridPosition)

  From the position of a cell in the grid, compute the size of the cell in dimension d. The size will be the standard cellDimensions unless the cell is at the border of the image in which case it might be truncated.

  Parameters:

  d - dimension index

  cellGridPosition - grid coordinates of the cell in dimension d.

  Returns:

  size of the cell in dimension d.

• getCellMin

  public long getCellMin(int d,
                         long cellGridPosition)

  From the position of a cell in the grid, compute the image position in dimension d of the first pixel of the cell (the offset of the cell in image coordinates).

  Parameters:

  d - dimension index

  cellGridPosition - grid coordinates of the cell in dimension d.

  Returns:

  offset of the cell in dimension d (in image coordinates).

• getCellGridPositionFlat

  public void getCellGridPositionFlat(long index,
                                      long[] cellGridPosition)

  From the flattened index of a cell in the grid, compute the position of a cell in the grid.

  Parameters:

  index - flattened grid coordinates of the cell.

  cellGridPosition - grid coordinates of the cell are written here.

• getCellPosition

  public void getCellPosition(long[] position,
                              long[] cellPos)

  Get the grid position of the cell containing the element at position.

  Parameters:

  position - position of an element in the image.

  cellPos - is set to the grid position of the cell containing the element.

• getCellPosition

  public void getCellPosition(long[] position,
                              Positionable cellPos)

  Get the grid position of the cell containing the element at position.

  Parameters:

  position - position of an element in the image.

  cellPos - is set to the grid position of the cell containing the element.
