There are two input files minimum.
File#1: This is the left or first input image given to
program TRACKER. Vectors will be grawn upon this
image with the base at the correct location.
File#2: This is the MARK file written by program TRACKER.
It is 'REAL' format with 512 byte records containing
pairs of tiepoints in the order:
left_line,left_samp,right_line,right_samp.
Files 3 to 101 are optional mark files forming a chain vector end to
end.
NOTE: all mark files must be the same size and length.
This is the output image. It is a copy of input #1 (in that format) with superimposed vectors contained in the MARK file. Vectors are drawn from left_line,left_samp to right_line,right_samp.
Exag is a real number which exaggerates the vector length. Default is exag=1.0
DN is an integer which sets the DN intensity value of the vectors. Default is n=255 If DN is negative then: 1. Vectors are drawn on an image of zero dn. 2. Vectors are written from 1 to 255 dn representing angles from 0 to 360 degrees. 3. No X is drawn at the vector base.
