% The grid_generator function will help you create grids of markers. The
|
|
10 |
% dialog has different options allowing you to create a marker grid which is rectangular,
|
|
11 |
% circular, a line or two rectangels of a shape or contains only of two
|
|
12 |
% markers. After choosing one of the shapes you will be asked for the base
|
|
13 |
% image which is typically your first image. After opening that image you
|
|
14 |
% will be asked to click at the sites of interest and the markers will be
|
|
15 |
% plotted on top of your image. You can choose if you want to keep these
|
|
16 |
% markers or if you want to try again.
|
|
17 |
% It has to be noted that you can
|
|
18 |
% always generate your own marker positions. Therefore the marker position
|
|
19 |
% in pixel has to be saved as a text based format where the x-position is
|
|
20 |
% saved as grid_x.dat and the y-position saved as grid_y.dat.
