.OUTPUT FILE: H_IMG041
[Enter the name for the output file.]
.ENTER DIMS NSAM, NROW: 64,64
[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.
For images of periodic arrays enter 'C' in the second position so that the padding will 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.) IMPORTANT: The option 'C' only works on 2D images.
.TOP LEFT COOS: 10,15
[Enter the coordinates of the output picture where the top
left corner of the input picture is to be put.]
