OSSIM-IMG2RR(1) User Commands OSSIM-IMG2RR(1)

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 varies from 0 to 100, where 100 is best. Currently only for JPEG compression
Compression type can be: NONE, JPEG, PACKBITS, or DEFLATE
Computes full histogram alongside overview.
Computes a histogram in fast mode which samples partial tiles.
Computes and writes out an alpha mask to a separate .mask file.
Will disable the elevation
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.
Will disable the plugin loader
Number of histogram bins. This will override the default for scalar type. Also this will force a separate pass.
Maximum histogram value to use. This will override the default for scalar type. Also this will force a separate pass.
Minimum histogram value to use. This will override the default for scalar type. Also this will force a separate pass.
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.
Lists the entries within the image
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".
Specifies the range of pixels to target for masking out.
Specifies the unique pixel value to target for masking out.
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.
Turns on min, max scanning when reading tiles. This option assumes the null is known.
Turns on min, max, null scanning when reading tiles. This option tries to find a null value which is useful for float data.
key:value NOTE: separate key value by a colon. Deprecated, use --writer-prop instead.
Defines the tile size for the supported overview handler.
Outputs version information.
Adds a property to send to the writer. format is name=value
specify individual keywords to add to the preferences keyword list: name=value
specify a preference file to load
specify the classes to trace, ex: ossimInit|ossimImage.* will trace ossimInit and all ossimImage classes
Wants to include full res dataset as well as reduced res sets.
Write overview to directory specified.
Give the entry(zero based) to build an overview for.
Shows help
Write overview to file specified. If used on a multi-entry file, given "foo.ovr" you willget: "foo_e0.ovr"
Rebuild overviews even if they are already present.
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".
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
