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
