I work in EPSG:27582

759770 meters entred become 759769.60
2053000 meters entred become 2052994.20

I think the problem come from the methode used to stock Y coordonnate in the world file. For my xxxxx-modified.tfw Y coordonnate of cornor of map is 2.05301e+06. It seems that type is not able to stock with enough precision. I think it possible to modify Y coordonate "with the hand" but if it's possible why not modify the program of qgis which do that

I think the probleme come also fom the storage of mapY in xxxx.tif.points.
but more generaly french lambert II extend nead that Y coordonate was stocked on 7 numbers and perhaps 2 decimals because of false northing = 2 200 000 meters.

I see now that problem because next I've use referenced points already write on paper map and these had luke to be ten round.

If georeferenced points are loaded in meter georeferencer unable good work with EPSG 27582 and certainly others.
