[...] The other way around. I want the grid staying snapped on the center. When I start the rotation tool, the center point and one cross of the grid are at the same location. When I move the center point to some other place, the formerly centered cross of the grid does not follow the center point. When I move the center point to e.g. the lower side of the edge of a building, if the cross would stay at the center point, I could then rotate as long as the grid goes along the edge of the building. At the moment, this is not the case, and so it becomes tricky to find out, if the rotation has aligned the picture to the frame of the picture. So I need to add more and more grid lines, so that comparing is easier. But just one grid line would be enough, if the grid is centered in the center point. Even a single cross would be enough then, and a grid not necessary. (But it's good to have it, to compare with other parts of the picture). > > If this indeed what you mean, then you'll have to modify (at least) > the following files: > app/tools/gimptransformtool.c - The base class for the transformation > tools in GIMP (rotate, shear, transform, scale).
