Reuse ground-control points / Command-line usage #153

Closed moermann closed 6 years ago

Hi Tim,

thanks for your great app. I have successfully rectified a map of North Sea oil & gas fields. Now I would like to use the ground-control points for warping again the same map, but stripped off all content except the gas fields.

But this map contains no references anymore, so it's impossible to locate ground-control points. So is it possible to import the ground-control points from another rectification?

If it's not possible online, can I do it offline with your ruby scripts?

You can download the control points from one map and upload to another one. Look for the "Control points" and click to open
