Yes, but since the comparison works on pixel images, you can't see the non-integer part of the shift. > Also, the rasterization that gets performed, is it anti aliased? Usually it is; we could turn it off and possibly make the images larger, but IIRC that slows things down. > It would seem that though shifts and changes in the lengths of the staves are > "common", small and relatively benign problems, rotations and scales > (magnifications) should be considered major disasters, right? Rotations do not generally happen. Virtually all the positioning is rectilinear, and scaling is also not common. What happens that objects end up in different locations, and sometimes variable objects (slurs, beams) have different sizes. -- Han-Wen Nienhuys - hanw...@gmail.com - http://www.xs4all.nl/~hanwen
