DESCALE ( int x, int n ) : int

jcopy_sample_rows ( ComponentBuffer input_array, int source_row, ComponentBuffer output_array, int dest_row, int num_rows, int num_cols ) : void
jcopy_sample_rows ( ComponentBuffer input_array, int source_row, byte output_array, int dest_row, int num_rows, int num_cols ) : void	Copy some rows of samples from one place to another. num_rows rows are copied from input_array[source_row++] to output_array[dest_row++]; these areas may overlap for duplication. The source and destination arrays must be at least as wide as num_cols.
jcopy_sample_rows ( byte input_array, int source_row, byte output_array, int dest_row, int num_rows, int num_cols ) : void
jdiv_round_up ( long a, long b ) : long	Compute a/b rounded up to next integer, ie, ceil(a/b) Assumes a >= 0, b > 0
jround_up ( int a, int b ) : int	Compute a rounded up to next multiple of b, ie, ceil(a/b)*b Assumes a >= 0, b > 0
