[Qgis-user] Clipping tool for non-georeferenced data

[Alexia Mondot]

I have to manage products. Some are georeferenced, some aren't.
I have the same actions to do on these products.

For all others, it seems to work.
That's why I am worried about this functionality.

So there is not a way to do that in qgis ?
It does not seem to be difficult to do.
Just to add the height if the image to the y coordinates the clipper got ?

Regards,
Alexia
