Woolz Image Processing  Version 1.7.0
Name
WlzRGBCombine - Combines domain objects to make a single RGBA domain object.
Synopsis
WlzRGBCombine [-a] [-h] [-i] [-o<out file>] [-n] [-m <match object>]
              [<red object>] [<green object>] [<blue object>] [<alpha object>]
Options
-a Include an alpha channel object.
-h Help, prints usage message.
-i Invert grey values.
-o Output file name.
-n Normalise the grey value range of the objects prior to combining them instead of the default which is to clamp them.
-m Match the histograms of the input objects to that of the given object.
Description
Combines the input domain objects with values to form an RGBA object in which the red, green, blue and alpha (optional) components are the input objects. Histogram matching and grey value normalisation may be used to allow better visual comparison between the components. By default the input grey values are clamped to the range 0 - 255, but they will be normalised to this range if the normalise flag is set. The optional object for histogram matching may either be a domain object with values or a histogram. By default the objects are read from the standard input (in the order given) and written to the standard output. Null objects may be specified using the word null inplace of a object filename.
Example
WlzRGBCombine -m hist.wlz -o rgb.wlz red.wlz null blue.wlz
Creates a new object rgb.wlz in which the red and blue channels are created from the grey value objects read from red.wlz and blue.wlz. The green channel is left empty because null is given on the command line. The read and blue channels have their values matched to the histogram of hist.wlz.
