= cmm =

Command line application used to compute min/max pixel values for an image. Outputs an ".omd" file. An omd file can help radiometric processing of images greater than 8 bits per pixel.

Note that omd files are also generated by [wiki:img2rr ossim-img2rr].

== Usage ==
{{{
ossim-cmm [options] <image_file>
}}}

== Options ==
{{{
  --disable-elev        Will disable the elevation
  --disable-notify      Takes an argument. Arguments are ALL, WARN, 
			NOTICE, INFO, FATAL, DEBUG.  If you want multiple 
			disables then just do multiple --disable-notify on the 
			command line. 
                        	All arguments are case insensitive.  Default is all are
                        	enabled.
  --ossim-logfile       takes a logfile as an argument.  All output messages are
                        redirected to the specified log file.  By default there
                        is no log file and all messages are enabled.
  -K                    specify individual keywords to add to the preferences
                        keyword list: name=value
  -P                    specify a preference file to load
  -T                    specify the classes to trace, ex: ossimInit|ossimImage.*
                        
will trace ossimInit and all ossimImage classes-
  -e or --entry         Give the entry(zero based) to compute min / max for.
                        NOTE: Option only valid with a single file.
  -h or --help          Display this information
  -l or --list-entries  Lists the entries within the image and returns without
                        doing anything else.
  -p                    print values to standard output

}}}

== NOTES ==

 - Default output is to a ".omd" file so if the image was "foo.tif" you will get a "foo.omd".
 - If the .omd file exists already this will open it and add or, overwrite the min, max keywords only.
 - If the -p option is used no .omd file will be written.
