.OUTPUT FILE: IMG041
[Enter the name for the output file.]
.ENTER DIMENSIONS (NSAM,NROW,NSLICE): 40,40,40
[Enter the dimensions of the output file. Each dimension
has to be equal to or larger than the corresponding
input file dimension.]
.AVERAGE?(Y/N), (B)ORDER, (M)INIMUM, (C)IRCULAR: YC
[Enter 'Y' if you want the background value of the output
picture to be equal to the input file's average.
Enter 'B' if you want the background value to be equal to
the average density value of the perimeter pixels in
the input file.
Enter 'M' if you want the background to be equal to the
minimum density value in the input file.
Enter a 'C' in second character of answer if you have an image of periodic arrays and want the padding to be circularly continuous as required in Fourier filtering of lattices; i.e., the parts of the small image that extend beyond the border of the large image will be wrapped around. Without the 'C' option these parts would just be left out. The option 'C' only works on 2D images.]
