pixelflip
converts pixel values
Usage
pixelflip [options] <output_type> <input_file> <output_file> <target_value> <replacement_value>
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 argument 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
-c or --clamp-value clamp values (any pixel with value larger than input
will be clamped to input)
-h or --help Display this information
-m Replacement mode (see notes below)
-o or --create-overview Creates and overview for the output image
-w output tile width(only valid with tiled output
types). Must be a multiply of 16
Replacement Mode
-m Replacement mode option explanation. Valid modes = "all", "partial", and "full" (default=all)
- all Any pixel with dn of target will be replaced.
- partial Target will be replaced only at least one subpixel(band) does not have the target.
- full Target will be repaced only if all subpixels(bands) have the target.
Example:
target = 0 replacement = 1 Pixel at (0, 0) r=0, g=0, b=0 Pixel at (0, 1) r=0, g=30, b=21 Mode is "all": Pixel at (0, 0) becomes r=1, g=1, b=1 Pixel at (0, 1) becomes r=1, g=30, b=21 Mode is "partial": Pixel at (0, 0) remains r=0, g=0, b=0 Pixel at (0, 1) becomes r=1, g=30, b=21 Mode is "full": Pixel at (0, 0) becomes r=1, g=1, b=1 Pixel at (0, 1) remains r=0, g=30, b=21
