NAME

       ossim-img2rr - ossim-img2rr

SYNOPSIS

       ossim-img2rr [options] <input file>

DESCRIPTION

       MPI running with 1 processors...

       Description: ossim-img2rr Creates overviews and optionally a histogram for the passed in image.

OPTIONS

       --compression-quality
              Compression quality varies from 0 to 100, where 100 is best.  Currently only for JPEG compression

       --compression-type
              Compression type can be: NONE, JPEG, PACKBITS, or DEFLATE

       --create-histogram
              Computes full histogram alongside overview.

       --create-histogram-fast
              Computes a histogram in fast mode which samples partial tiles.

       --create-mask
              Computes and writes out an alpha mask to a separate .mask file.

       --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  argument  are  case
              insensitive.  Default is all are enabled.

       --disable-plugin
              Will disable the plugin loader

       --histogram-bins
              Number  of histogram bins.   This will override the default for scalar type.  Also this will force
              a separate pass.

       --histogram-max
              Maximum histogram value to use.  This will override the default for scalar type.  Also  this  will
              force a separate pass.

       --histogram-min
              Minimum  histogram  value to use.  This will override the default for scalar type.  Also this will
              force a separate pass.

       --histogram-r0
              Forces create-histogram code to compute a histogram using r0 instead of  the  starting  resolution
              for the overview. Requires a separate pass of R0 layer.

       --list-entries
              Lists the entries within the image

       --mask-mode <mode>
              Specifies  how to treat multi-band imagery when determining whether pixel will be masked according
              to the  defined  target  value  or  range.  Possible  modes  are:  "mask_full_and_partial_targets"
              (default) | "mask_only_full_targets".

       --mask-range <min> <max>
              Specifies the range of pixels to target for masking out.

       --mask-value <target>
              Specifies the unique pixel value to target for masking out.

       --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.

       --scanForMinMax
              Turns on min, max scanning when reading tiles.  This option assumes the null is known.

       --scanForMinMaxNull
              Turns on min, max, null scanning when reading tiles.  This option tries to find a null value which
              is useful for float data.

       --set-property
              key:value NOTE: separate key value by a colon.  Deprecated, use --writer-prop instead.

       --tile-size
              Defines the tile size for the supported overview handler.

       --version
              Outputs version information.

       --writer-prop
              Adds a property to send to the writer. format is name=value

       -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

       -a or --include-fullres
              Wants to include full res dataset as well as reduced res sets.

       -d     Write overview to directory specified.

       -e or --entry
              Give the entry(zero based) to build an overview for.

       -h or --help
              Shows help

       -o     Write overview to file specified.  If used on a multi-entry file,  given  "foo.ovr"  you  willget:
              "foo_e0.ovr"

       -r or --rebuild
              Rebuild overviews even if they are already present.

       -s     Stop  dimension for overviews.  This controls how many layers will be built. If set to 64 then the
              builder will stop when height and width for current level are less than or equal to  64.   Note  a
              default can be set in the ossim preferences file, setting the keyword "overview_stop_dimension".

       -t or --type
              see list at bottom for valid types. (default = ossim_tiff_box)

       Valid overview types: ossim_tiff_box ossim_tiff_nearest

       Example command building j2k overviews with a histogram removing/overwriting any existing overviews:

       ossim-img2rr -r -t ossim_kakadu_nitf_j2k --create-histogram image.tif
