xrg

xrg

USAGE: xrg inimg point_file [-L]

xrg calculates the area of each region in a binary image
by pixel filling using an interior point as
the starting point.

ARGUMENTS:
        inimg: input image filename (TIF)
   point_file: list of centroid coordinates
               as generated by spp (.vin)

OPTIONS:
-L: print Software License for this module

Example:

xrg coarbin.tif coarah.vin

coarbin.tif: (see threshm example)

coarah.vin: (generated from xcp)
