= icp =

Image copy. Converts images from one format to another. Can also be used to chip or crop existing images  If you wish to resample or reproject your data, use [wiki:orthoigen] instead.

The iView GUI application operates as a viewer and a way to set up parameters for icp.  icp can be called from the command line or from an application - e.g. iView.

  -a or --use-scalar-remapper  Uses scalar remapper, transforms to 8-bit
  -b or --bands                uses the specified bands: ex. "1, 2, 4" will
                               select bands 1 2 and 4 of the input image.  Note:
                               it is 1 based
  -c or --compression-type     Uses compression.  Currently valid for only tiff
                               output -c jpeg will use jpeg compression
  -e or --entry                For multi image handlers which entry do you wish
                               to extract
  -h or --help                 Display this information
  -l or --start-line           Which start line do you wish to copy from the
                               input. If none is given then 0 is used
  -o or --create-overview      Creates and overview for the output image
  -p or --end-sample           Which end sample do you wish to copy from the
                               input.  If none is given then max sample is used
  -q or --compression-quality  Uses compression.  Valid for jpeg type. default
                               is 75 where 100 is the best and 1 is the worst
  -r or --res-level            Which res level to extract from the input: ex -r
                               1 will get res level 1
  -s or --start-sample         Which start sample do you wish to copy from the
                               input.  If none is given then 0 is used
  -t or --create-thumbnail     Takes an argument which is the maximum pixel
                               dimension desired.
