tic - Write tic marks on a cube
This program may be used to mark the position of control points of some
kind such as ground control, reseau locations, etc.  TIC will copy the
input cube to the output cube and then mosaic the tic mark array
described in the TIC file to every position listed in the CONT file
(control point file).  0 DN's in the TIC file will not be overlayed on
the output cube (they will be transparent).

ADDITIONAL NOTES:

Parm	Description
FROM	Input cube file name. If the file extension is omitted, the ".cub" will be assumed.
TO	Output cube file name. If the file extension is omitted, the ".cub" will be assumed.
TIC	The ticmark is mosaicked on to the file, such that 0 dn is transparent. The format of the ASCII tic mark file is: number of samples (ns), number of lines (nl) density(1,1),density(1,2),density(1,3)...density(1,ns) density(2,1),density(2,2),density(2,3)...density(2,ns) . . . . . . . . density(nl,1),density(nl,2),density(nl,3)...density(nl,ns) ex: 5,5 255,0,0,0,255 0,255,0,255,0 0,0,255,0,0 0,255,0,255,0 255,0,0,0,255 This example will create a 5 by 5 pixel x for a tic mark. The maximum ns,nl is 15,15 and odd numbers should be used so that an odd pixel is in the center. Note that the density numbers are integer values.
CONT	Format of tic mark location file is samp,line separated by commas with one position per line. Ex: 1, 1 5.3, 6.0 This will place the center of a tic mark at samp 1, line 1 and at samp 5, line 6. Decimal values of sample, line positions will be accepted, but a tic mark will be plotted at the nearest integer position.
