Method Detail

createCellGrid

public static CellGrid createCellGrid(long[] dimensions,
                                      int[] cellDimensions,
                                      Fraction entitiesPerPixel)

Creates a CellGrid with the given dimensions and cellDimensions. Also checks whether the given cellDimensions lead to cells that are too large to fit into one primitive array.

computeCellDimensions

public static int[] computeCellDimensions(Imaris.IDataSetPrx dataset,
                                          int[] invMapDimensions,
                                          int[] optionalCellDimensions)

Compute the cell dimensions from block size of dataset, optionally overridden by user-defined optionalCellDimensions.

Parameters:

dataset - dataset handle (to get block sizes from)

invMapDimensions - maps imglib2 dimensions to imaris dimensions. Note that the length of this array is the number of imglib dimensions

optionalCellDimensions - optionally overrides cell dimensions derived from the dataset (can be null otherwise). This is truncated or extended (by replicating the last element) to the required number of dimensions

Returns:

imglib2 cell dimensions.
