# PipelinePanSharp.sml
# Sample script that illustrates
# 1) the use of a custom dialog window constructed using an XML dialog specification
# 2) assembly of an Image Pipeline using options set from the dialog
# The script computes a pan-sharpened color-composite image from three low-resolution bands
# of a multispectral image (must match each other in dimensions and extents) and a higher-resolution
# panchromatic image. The low-res bands must overlap but need not match the extents of the hi-res
# image; the low-res composite image is automatically resampled to match the extents of the hi-res
# image before the multiresolution fusion stage.
# The pan-sharpened image can be saved as an RVC raster object or as a TIFF, PNG, JP2, or JPEG file.
# If the Apply Contrast option is selected for an input raster,
# the last-used contrast table is used to set up a filter to apply contrast to that
# raster before further processing. If no contrast table is found, a
# default normalized contrast table is automatically computed and used.
