Synopsis

WlzHistogramRebin [-o<output object file>] [-a] [-h]
           [-i] [-f] [-n<bins>] [-s<start>] [-w<width>]
           [<input object file>]

Options

-a	output the histogram as ascii data not a Woolz histogram object.
-i	create integer bin values.
-f	create (double precision) floating point bin values.
-n	number of histogram bins.
-s	start value, lower limit of histogram.

-o	Output object file name.
-h	Help - print help message

By default the input histogram object is read from the standard input and the output histogram data/object is written to the standard out- put. The default number of bins, origin and bin width values are those of the input histogram object.

Description

Re-bins a Woolz histogram object as required.

Output ascii data are written as a set of records one per line, with each record composed of two fields separated by white space characters:

<grey value> <histogram bin occupancy>

Examples

# An example which uses WlzHistogramRebin and xgraph to plot a
# histogram with 256 bins, starting at 0 and with a bin width
# of 1.
