The input graphics file(s). The maximum number of files is 19.
The output graphics file(s). The maximum number of files is 19.
The dimension of the input graphics files.
Keyword for the operation to perform:
'APPEND Appends graphics files. All of the input files are assumed
to have dimension of DIM. Output file has same dimension.
'SWAP Swaps first two coordinates of each set (e.g. x-y to y-x).
'3DTO2D Converts a 3D file whose third coordinate is a file or level
number to multiple 2D files. The file number of a line string
is the integer part of the third coordinate in the first set.
Linestrings whose file number is outside the range (one to
the number of output files) are not output.
'2DTO3D Converts multiple 2D files to one 3D file with the third
coordinate containing the file number. The third coordinate
in each set (except the zero terminator) contains the file
number (i.e. 1, 2, . . .).
'REDIM Changes the dimension of the file. The dimension of the output
file is specified with the OUTDIM parameter. If the output
dimension is smaller than the input then only the beginning
coordinates are used. If the output dimension is larger then
the extra coordinates are zero.
'FILL Adds points to line strings so there is a point every INTERVAL
distance. Every point in the input file is transfered to the
output file. If points in the original file are larger than the
specified distance apart, then points are added on the joining
lines with the appropriate spacing. The distance calculations
are performed in 2-D, i.e. using the first two coordinates.
'SMOOTH Lowers the spatial resolution of a graphics file by deleting points
so that the points are greater than INTERVAL distance apart.
The first point in every line string is output. Succeeding points
are output if they are greater than the specified distance from
the previously output point. The distance calculations
are performed in 2-D, i.e. using the first two coordinates.
The dimension of the output graphics file for the REDIM option.
INTERVAL specifies the desired point spacing in the graphcis line strings for the FILL and SMOOTH options.
