INP
The input image, which is a standard VICAR raster image. In the image, pixel
values not equal to the BACKground value are considered lines, and are
converted into vectors.
OUT
Output Graphics I file.
SIZE
The size parameter determines the boundaries in the input
file from which the copy is to take place. It is specified
as (SL,SS,NL,NS), where
SL is the starting line
SS is the starting sample
NL is the number of lines to be copied
NS is the number of samples (pixels) in each line
SL
Starting line, the first image line to be examined for output vectors.
SS
Starting sample, the leftmost image pixel to be examined for output vectors.
NL
Number of lines to be examined for output vectors.
NS
Number of pixels per line to be examined for output vectors.
DIM
DIM specifies the number of dimensions of the output graphics file, either
2 or 3. If DIM=3, the third dimension is used to store the DN of the line.
BACK
BACK specifies the DN of background pixels. All pixels that are not of this
DN are included as part of an output vector.
